Proposed NASS instructions and/or definitions |
|||
Date of cycle reporting |
Add |
Not currently collected |
New variable added for prospective data entry.
The addition of the “date of cycle reporting” is necessary for the implementation of prospective data reporting. This type of reporting provides more accurate information on success rates because it reduces potential misclassification of cycles. The date is needed to ensure that initial reporting of cycle intent and selected patient information occurs within 4 days of cycle start, as outlined in the revised Federal Registry Notice.
|
Indicate the date when cycle is being reported. Always record the month first, using the two-digit equivalent (e.g., January = 01, February = 02). Record two digits for the day, and four digits for the year. |
||
NASS Patient ID |
Unchanged |
This ID is generated by the NASS system. If you are using this worksheet to enter data for a new patient in NASS, the NASS Patient ID will be generated and displayed on the screen after you have selected to add a new patient. |
No changes recommended. |

Patient Optional Identifiers
|
Modify |
Optional Identifier 1 [max 3 characters] Optional Identifier 2 [max 4 characters] |
Revised to allow expanded number of characters — current number of characters may not be sufficient for clinics.
|
Optional Identifier 1 Optional Identifier 2 [expanded number of characters allowed] |
||
Date of Birth (Patient) |
Unchanged |
Date of Birth: It is critical to enter the patient’s month, day, and year of birth. Always record the month first, using the two-digit equivalent (e.g., January = 01, February = 02). Record two digits for the day, and four digits for the year. |
No changes recommended.

||
Sex of patient seeking ART |
Add |
Not currently collected |
New variable added to determine sex of patient seeking ART services. This variable allows for differentiation between male and female patients using ART services. This will also allow for appropriate skip patterns for male patients (e.g., questions on female patient history will not be shown).
|
Indicate the sex of the patient seeking ART (male or female) |
||
Cycle start date |
Modify |
Date current cycle started: Enter the
start date of the current cycle using NASS date reporting
conventions as indicated on the screen. The cycle start date
depends on the type of cycle as described below. |
The definitions were modified to include specific information on flare-gonadotropin cycles, which was a common reporting discrepancy due to clinic misinterpretationStimulated and unstimulated cycles were further clarified in the examples provided for the different definitions. This will facilitate more accurate calculation of cycle start date.
|
Indicate the cycle start date, determined
as follows (dates should be entered as mm/dd/yyyy):
|
||
Patient US Resident |
Modify |
Primary residence in U.S.: Use the drop-down list to indicate whether the patient's main residence is in the United States or its territories (regardless of legal residency status). Primary residence refers to the place where the person usually lives. U.S. territories that should be considered include Puerto Rico, Guam, U.S. Virgin Islands, American Samoa, Northern Mariana Islands, Wake Island, and Johnston Atoll. If primary residence of the patient is unknown, select “Not ascertained by clinic” from the drop-down menu. |
Removed the “not ascertained by clinic” option to discourage non-report of residency. |
Indicate whether the patient's primary residence during the current cycle is in the United States or its territories (regardless of legal residency status). Primary residence refers to the place where the person usually lives. U.S. territories that should be considered include Puerto Rico, Guam, U.S. Virgin Islands, American Samoa, Northern Mariana Islands, Wake Island, and Johnston Atoll. If patient refuses to answer, select “refused”.
|
||
Patient Country of Residence (if not United States) |
Unchanged |
Country of primary residence: If you entered “Yes” for Primary residence in U.S., then “United States” will be automatically entered into the Country of primary residence field. If you entered “No” in the Primary residence in U.S. field, you must use the drop-down list to select the country where the patient resides. The drop down list of countries is arranged alphabetically. If unknown, leave the ---Select--- box as is. Tip: Select “United Kingdom” for patients whose primary residence is England or Great Britain. |
No changes recommended. |

Intended cycle type |
Modify |
Intended Transfer Method (Select all that apply): Check the box next to each intended transfer method for the current cycle.
|
Given the recent increases in oocyte and embryo banking and the potential for these cycles to be underreported (see justification for the next question), an option was added to indicate that the cycle was intended for oocyte or embryo banking.
Reference: Kushnir VA, Vidali A, Barad DH, Gleicher N. The status of public reporting of clinical outcomes in assisted reproductive technology. Fertil Steril. 2013;100:736-41. |
Intended Transfer Method (Select all that apply): Check the box next to each intended transfer method for the current cycle.
IVF: In vitro fertilization is a method of assisted reproduction that involves removing oocytes from a woman’s ovaries, combining them with sperm in the laboratory, and after fertilization and culture, placing the resulting embryo(s) into the woman’s uterus.
ZIFT or TET: Zygote intrafallopian transfer is a procedure in which the oocytes are collected and fertilized, and the resulting zygotes are then transferred to the fallopian tube. Tubal embryo transfer (TET) is the transfer of early stage embryos to the fallopian tube.
EMBRYO/OOCYTE BANKING: Indicate if the current cycle is intended to be an oocyte or embryo banking cycle initiated with the intent of cryopreserving all oocytes or fertilized embryos for later use. This does not apply to cycles initiated with the intent to transfer embryos, but for which all embryos were subsequently cryopreserved (regardless of the reason).
|
||
Embryo or oocyte banking type |
Modify |
Embryo or oocyte banking cycle: Click on either “Yes” or “No” to indicate if the current cycle is intended to be an embryo banking, oocyte banking, or donor oocyte banking cycle initiated with the intent of cryopreserving all oocytes or fertilized embryos for later use. This does not apply to cycles initiated with the intent to transfer embryos, but for which all embryos were subsequently cryopreserved (regardless of the reason).
|
Question was revised to include a sub-question for indicating banking type (oocyte or embryo banking) and duration of banking (if banking was indicated).
Collecting information on cycles intended for embryo/oocyte banking only allows more accurate calculation of clinic success rates by reducing misclassification of cycles intended only for banking oocytes or embryos. Oocyte banking is no longer considered experimental; thus increased use of oocyte banking is anticipated. Furthermore, long term banking (≥12 months) is indicative of fertility preservation, a practice that has become increasingly common and for which the long term health implications are not known. Short term banking often represents a preference to using frozen oocytes/embryos in the immediate future due to some evidence of better success rates with frozen embryos.

If cycle is for banking only, specify the banking type (select all that apply): embryo banking or oocyte banking.
EMBRYO BANKING: An embryo banking cycle is defined as a cycle initiated with the intent of cryopreserving all fertilized embryos for later use. This does not apply to cycles initiated with the intent to transfer embryos but for which all embryos were subsequently cryopreserved for use in future cycles.
AUTOLOGOUS OOCYTE BANKING: An oocyte banking cycle is defined as a cycle initiated with the intent of cryopreserving all un-fertilized oocytes for later use. This does not apply to cycles initiated with the intent to transfer embryos. Autologous oocyte banking refers to cycles where the patient is banking her own oocytes for later use.
DONOR OOCYTE BANKING: An oocyte banking cycle is defined as a cycle initiated with the intent of cryopreserving all un-fertilized oocytes for later use. This does not apply to cycles initiated with the intent to transfer embryos. Donor oocyte banking refers to cycles where a donor is banking oocytes for use by someone else at a later date.
|
||
Intended duration of oocyte banking |
Add |
Not currently collected |
Long term banking (≥12 months) is indicative of fertility preservation, a practice that has become increasingly common and for which the long term health implications are not known. Furthermore, increasing numbers of women are choosing to freeze their oocytes or embryos prior to undergoing surgery, radiation or other gonadotoxic medical treatments for malignancies. Although the American Clinical Oncology Society and the American Society for Reproductive medicine both recommend that providers discuss fertility preservation options with patients treated for malignancy during their reproductive years, there are currently no surveillance data regarding the use of fertility preservation among this population.
Short term banking often represents a preference for using frozen oocytes/embryos in the immediate future due to some evidence of better success rates with frozen embryos.

Intended embryo source |
Modify |
Patient: Intent to use patient’s oocytes/embryos, fertilized with partner or donor sperm
Donor: Intent to use donor oocytes/embryos, fertilized with partner or donor sperm |
|
Indicate the intended embryo source (select ALL that apply):
PATIENT EMBRYOS: Intent to use patient’s embryos, fertilized with partner or donor sperm
DONOR EMBRYOS: Intent to use donor embryos, fertilized with donor sperm
|
||
Intended Oocyte Source and state |
Modify |
Patient: Intent to use patient’s oocytes/embryos, fertilized with partner or donor sperm
Donor: Intent to use donor oocytes/embryos, fertilized with partner or donor sperm
FRESH: Intent to transfer fresh oocytes/embryos retrieved during this cycle
FRESH: Intent to transfer fresh oocytes/embryos retrieved during this cycle
FROZEN: Intend to transfer thawed embryos retrieved during a previous cycle
Note: The sperm source may be either the patient’s partner or a sperm donor selected by the patient. |
Two separate questions on oocyte/embryo source and type were combined into one question that distinguishes between patient oocytes and donor oocytes, fresh or frozen. Previous questions did not differentiate between use of patient oocyte versus use of donor oocyte (only donor embryo was collected). This change will eliminate misclassification of cycles and therefore improve methods for calculating success rates.
|
Check the box next to each intended oocyte/embryo source and state for the current cycle. (select all that apply):
PATIENT OOCYTE: Intend to use patient’s oocytes
DONOR OOCYTE: Intend to use donor’s oocytes.
NOTE: the oocyte donor can include the female same sex partner in situations where one partner is donating the oocytes and the other is carrying the pregnancy.
FRESH: intend to use fresh oocytes or embryos retrieved during this cycle
FROZEN: intend to use thawed oocytes or embryos from a previous cycle
UNKNOWN: Select only if oocyte source is not known when using donor embryos |
||
Intended Sperm Source (Partner, Donor, Mixed) |
Modify |
Source of semen used for fertilization: Use
the drop-down list to select the source of semen used for
fertilization during this patient’s ART cycle.
|
Question revised for prospective data collection to reflect intent and to change from “semen” to “sperm”. An additional category for “patient” was added for those cycles where the patient is male. The “mixed” option was eliminated since the clinic can select all sources that are applicable. |
Select the intended source of sperm for
fertilization during this patient’s ART cycle. (SELECT ALL
THAT APPLY)
PATIENT (if male): Sperm used to
fertilize the oocytes is that of the patient. |
||
Intended pregnancy carrier |
Modify |
Intended transfer method: Gestational carrier (yes/no).
Gestational carrier is a woman who gestates an embryo that did not develop from her egg with the expectation of returning the infant to its intended parents. |
Question was revised to include options for patient, gestational carrier, or none (e.g., an oocyte or embryo banking cycles). The instructions were revised to note that 2 cycles should be reported if both the patient and a gestational carrier are used. |
Indicate whether the intended carrier for this cycle is the patient, a gestational carrier (a woman who gestates an embryo that did not develop from her oocyte, with the expectation of returning the infant to its intended parent(s)), or none (in the case of cycles only intended for oocyte or embryo banking) NOTE: if the intended carrier is a patient and gestational carrier, 2 cycles should be reported. For female same sex couples, the woman who will carry the pregnancy should be identified as the patient. |
||
Cycle type |
Modify |
Intended Transfer Method (Select all that
apply): Check the box next to each intended transfer method for
the current cycle. |
Question revised slightly to remove intent
for the purpose of collecting information on the procedures that
were actually performed, which may differ from what was intended
at the cycle start due to factors such as inadequate number of
oocytes retrieved, detection of chromosomal abnormalities during
PGD, or development of ovarian hyperstimulation syndrome. By
requiring clinics to prospectively report intended cycle type
followed by the actual cycle type, we will be better able to
accurately calculate success rates and evaluate differences
between intent and actual treatment methods. Most importantly,
this will reduce inaccurate reporting of cancelled cycles. Also,
given the recent increases in oocyte/embryo banking, an option
for oocyte/embryo banking was added.
|
Indicate cycle type (select all that apply)
IVF: In vitro fertilization is a method of assisted reproduction that involves removing oocytes from a woman’s ovaries, combining them with sperm in the laboratory, and after fertilization and culture, placing the resulting embryo(s) into the woman’s uterus.
EMBRYO/OOCYTE BANKING: Indicate if the current cycle is an oocyte or embryo banking cycle initiated with the intent of cryopreserving all oocytes or fertilized embryos for later use. This does not apply to cycles initiated with the intent to transfer embryos, but for which all embryos were subsequently cryopreserved (regardless of the reason).
|
|
|
Embryo source |
Modify |
Patient: Intent to use patient’s oocytes/embryos, fertilized with partner or donor sperm
Donor: Intent to use donor oocytes/embryos, fertilized with partner or donor sperm |
|
Indicate the embryo source (select ALL that apply):
PATIENT EMBRYOS: used patient’s embryos, fertilized with partner or donor sperm
DONOR EMBRYOS: used donor embryos, fertilized with donor sperm
|
|
|
Oocyte Source and state |
Modify |
Patient: Intent to use patient’s oocytes/embryos, fertilized with partner or donor sperm
Donor: Intent to use donor oocytes/embryos, fertilized with partner or donor sperm
FRESH: Intent to transfer fresh oocytes/embryos retrieved during this cycle
FRESH: Intent to transfer fresh oocytes/embryos retrieved during this cycle
FROZEN: Intend to transfer thawed embryos retrieved during a previous cycle
Note: The sperm source may be either the patient’s partner or a sperm donor selected by the patient. |
Question revised to ask separate questions
on intent for the purpose of collecting information on actual
oocyte/embryo source and state. By requiring clinics to
prospectively report oocyte/embryo source and state followed by
the actual source and state, we will be better able to accurately
calculate success rates and evaluate differences between intent
and actual treatment methods. Two separate questions on oocyte/embryo source and type were combined into one question that distinguishes between patient oocytes/embryos and donor oocytes/embryos, fresh or frozen. Previous questions did not differentiate between patient oocyte and embryo. This change will eliminate misclassification of cycles and therefore improve methods for calculating success rates.
|
Indicate oocyte/embryo source for current cycle (select all that apply):
PATIENT OOCYTE: Used patient’s oocytes
PATIENT EMBRYO: Used patient’s embryos fertilized with patient, partner or donor sperm
DONOR OOCYTE: Used donor’s oocytes
DONOR EMBRYO: Used donor’s embryos fertilized with patient, partner or donor sperm
NOTE: the oocyte donor can include the female same sex partner in situations where one partner is donating the oocytes and the other is carrying the pregnancy.
FRESH: Used fresh oocytes or embryos retrieved during this cycle
FROZEN: Used thawed oocytes or embryos from a previous cycle
UNKNOWN: Select only if oocyte source is not known when using donor embryos

Reason for ART |
Modify |
Reason for ART: Check the box next to all
reasons that apply that make the patient (and partner) a
candidate for ART. For on-screen definitions, click on the
reasons or question marks to show/hide the definitions. |
Reason for ART has consistently high discrepancy rates since the inception of NASS. About 20% of discrepancies are due to a single wrong diagnosis reported (usually other or unexplained). This question was revised to add additional options to increase the specificity of the question and to reduce the likelihood that clinics will select other/unexplained. Type of infertility is directly related to treatment success and has been shown to differentially impact perinatal outcomes; thus accurate information is needed to properly evaluate differences in treatment outcomes.

- Azoospermia, obstructive - Azoospermia, non-obstructive - Oligospermia, severe - Oligospermia, moderate - Low motility - Low morphology
Definitions: Male infertility: Medical condition: Significant medical conditions presenting as, or contributing to, male infertility (i.e., hormonal and oxidative dysfunction such as diabetes mellitus, thyroid disease, pituitary adenoma, hypopituitarism, cancer of prostate or testes, retroperitoneal and spinal cord tumors, polycycstic kidney disease, varicocele, retrograde ejaculation, infection, inflammation and autoimmunity involving the genitourinary system, etc.)
Genetic or chromosomal abnormality: Presence of a laboratory documented genetic condition known to be associated with male infertility (Y chromosome microdeletion, Klinefelter syndrome, Cystic Fibrosis etc.) Specify abnormality type.
Abnormal sperm parameters (indicate findings from semen analysis)
History of endometriosis: This is the presence of tissue resembling endometrium in locations outside the uterus such as the ovaries, fallopian tubes, and abdominal cavity; a history of all stages of endometriosis (minimal to severe) whether treated or not, may be a reason for ART.
Tubal ligation for contraception: Sterilization of the female by constricting, severing, or crushing the fallopian tubes; constriction may be with an encircling plastic ring or other ligature.
Other
Tubal Disease: Any other tubal
disease, including, but not limited to, pelvic or peritubal
adhesive disease, prior tubal surgery, prior ectopic pregnancy,
or tubal occlusion (partial or complete without current or prior
hydrosalpinx) Ovulatory disorders: This includes one or more disorders causing reduced fecundity associated with structural, anatomic, or functional impairment of one or both ovaries;,
PGD as primary reason for ART - Any cycle in which a patient undergoes IVF for the primary purpose of conducting preimplanatation genetic screening or diagnosis. This option should only be selected if the patient is trying to prevent transmission of inherited disease.
Oocyte or embryo banking as reason for ART – cycles where oocyte or embryo banking is reason for ART
Indication for use of gestational carrier.
Recurrent pregnancy loss (a disease distinct from infertility, defined by two or more failed pregnancies). This includes cycles in which IVF with PGD is performed to exclude oocytes/embryos with chromosomal abnormalities to reduce the likelihood of recurrent pregnancy loss.
Other causes (please specify)
Unexplained Infertility: Infertility in which no etiology has been identified.

|
Female Patient Height |
Unchanged |
Report height in units as recorded in medical chart. Do not convert measurements.
(Report in Feet and/or Inches or Centimeters or Unknown)
|
No changes recommended. |
Report height of female patient in units as recorded in medical chart. Do not convert measurements.
(Report in Feet and/or Inches or Centimeters or Unknown) |

|
Female Patient Weight at the start of this cycle:
|
Unchanged |
Report weight in units as recorded in medical chart. Do not convert measurements.
(Report in Pounds or Kilograms or Unknown)
|
No changes recommended. |
Report weight of female patient in units as recorded in medical chart. Do not convert measurements.
(Report in Pounds or Kilograms or Unknown)
|
|
|
History of cigarette smoking |
Modify |
Has this patient smoked at least 100 cigarettes during entire life?
Yes No Unknown
During the 3 months before this cycle started, did the patient smoke any cigarettes?
Yes No Unknown
If patient smoked cigarettes during the 3 months before this cycle, on average, how many cigarettes per day did the patient usually smoke during those 3 months?
|__|__| Number of cigarettes smoked per day during the 3 months before this cycle.
or
Patient smoked less than 1 cigarette per day on average, during the 3 months before this cycle. (For example, patient smoked less than 7 cigarettes per week, or smoked a couple cigarettes only on weekends)
or
Unknown how many cigarettes the patient smoked per day during the 3 months before this cycle
|
The question was revised to eliminate the question on lifetime smoking and to focus on smoking during the 3 months prior to the cycle start.
Accurate collection of this variable is needed due to the association between smoking and infertility as well as increased risk for spontaneous abortion and ectopic pregnancy among smokers.
Reference: Smoking and infertility: a committee opinion. Fertil Steril. 2012 Sep 5.
|
Did the patient smoke during the 3 months before the cycle started?
Yes No Unknown |
|
|
Prior pregnancy |
Add |
Gravidity (as defined in another question): Gravidity is defined as the total number of prior pregnancies a patient has had. This includes ectopic pregnancies, and pregnancies that ended in therapeutic abortion, spontaneous abortion, stillbirth, or live birth. |
This is a “top-level” question that determines whether all subsequent questions on pregnancy history are shown (i.e., except for duration of infertility, the subsequent questions on pregnancy history are not relevant). NASS currently collects information on number of previous pregnancies, but this new, “top-level” question allows for skip patterns for those with no previous pregnancies.
|
Click on either “Yes” or “No” to indicate if the female patient had any prior pregnancies.
This includes ectopic pregnancies, biochemical pregnancies, and pregnancies that ended in therapeutic abortion, spontaneous abortion, stillbirth, or live birth. |
|
|
Months attempting pregnancy (if couple is not surgically sterile) |
Add |
Not currently collected |
New variable. Duration of infertility has been identified as a predictor of success rates. Studies have also shown that women with a long time to pregnancy have increased risk for preterm birth. Thus, collection of information on the duration of infertility can help distinguish the potential effect of underlying infertility on success rates and adverse perinatal outcomes following ART.
NOTE: question will only be shown if answered “yes” to prior pregnancy.

|
Female Patient Gravidity |
Modify |
Gravidity: Gravidity is defined as the total number of prior pregnancies a patient has had. This includes ectopic pregnancies, and pregnancies that ended in therapeutic abortion, spontaneous abortion, stillbirth, or live birth. |
Question was revised to include biochemical pregnancies in the definition for completeness. This is consistent with NCHS definition for gravidity which includes the total number of times a woman has been pregnant, regardless of regardless of whether the pregnancy resulted in a live birth.
NOTE: question will only be shown if answered “yes” to prior pregnancy.
|
If any prior pregnancies reported, enter the total number of prior pregnancies (gravidity)
Gravidity is defined as the total number of prior pregnancies a patient has had. This includes ectopic pregnancies, biochemical pregnancies, and pregnancies that ended in therapeutic abortion, spontaneous abortion, stillbirth, or live birth.
|
|
|
Prior Full-Term Births |
Unchanged |
Number of prior full term births (>=37 weeks): Enter the total number of prior live and stillbirths a patient has had that reached 37 completed weeks gestation. Births are counted by birth events (e.g., triplets would be counted as one birth).
|
No changes recommended.
NOTE: question will only be shown if answered “yes” to prior pregnancy.
|
Enter the total number of prior births a female patient has had which reached 37 completed weeks gestation. This includes both live births and stillbirths. Births are counted by birth events (e.g. a triplet birth is counted as one).
A birth (delivery) in which at least one fetus was live born (showed signs of life after the complete expulsion or extraction from its mother). Signs of life include breathing, beating of the heart, pulsation of umbilical cord, or definite movement of voluntary muscles. Any birth event in which an infant shows signs of life should be counted as a live birth, regardless of gestational age at birth.
|
|
|
Prior Preterm Births |
Unchanged |
Number of prior preterm births (>=20 & <37 weeks): Enter the total number of prior live and still births a patient has had that were at least 20 but less than 37 completed weeks gestation. Births are counted by birth events (e.g., triplets would be counted as one birth). |
No changes recommended.
NOTE: question will only be shown if answered “yes” to prior pregnancy.
|
Enter the total number of prior births a female patient has had that were at least 20 but less than 37 completed weeks gestation. This includes both live births and stillbirths. Births are counted as birth events (e.g. a triplet birth is counted as one).
|
|
|
Number of Prior Stillbirths |
Add |
Instructions - N/A
Stillbirth defined as birth (delivery) at 20 weeks of gestation or later (or 18 weeks or later from the date of transfer if the pregnancy was achieved using ART) in which no fetus showed signs of life after the complete expulsion or extraction from the mother. |
New variable. Previous stillbirth is a risk factor for stillbirth in subsequent pregnancies. Therefore, previous stillbirth may explain variations in live birth rates following ART.
The current stillbirth definition was revised to include a birth weight threshold when gestational age is not known (consistent with the NCHS definition of stillbirth).
NOTE: question will only be shown if answered “yes” to prior pregnancy.

Stillbirth is a birth (delivery) after completion of 20 weeks of gestation (if the gestational age is known), or a weight greater than or equal to 350 grams (if the gestational age is not known) in which the fetus showed no signs of life after the complete expulsion or extraction from the mother. Stillbirths should be counted as infant-level events (e.g. a twin pregnancy with one stillbirth and one live birth would be reported as one and a twin pregnancy with two stillbirths would be reported as two).

Prior Spontaneous Abortions (miscarriage) |
Unchanged |
Number of prior spontaneous abortions (<20 weeks): This is the total number of prior clinical pregnancies ending in spontaneous loss of the entire pregnancy prior to completion of 20 weeks of gestation (or 18 weeks from the date of transfer if the pregnancy was achieved using ART). These are also known as miscarriages. |
No changes recommended.
NOTE: question will only be shown if answered “yes” to prior pregnancy.

Prior stimulations for ART |
Modify |
Number of prior fresh ART cycles: Enter the
number of fresh ART cycles started before the initiation of this
cycle. ART is defined as all treatments or procedures that
include the handling of sperm or embryos for the purpose of
establishing a pregnancy. This includes but is not limited to
IVF, transcervical embryo transfer, GIFT, ZIFT, and TET. ART
does not include assisted insemination. A prior ART cycle is
defined as any cycle in which: |
Question was reworded to “prior stimulations for ART” (instead of prior ART cycles) for clarity. Definition was revised to include definition of stimulation and to add note that stimulations for prior cancelled cycles should also be included. |
Number of prior stimulations for ART: Enter the number of prior stimulations for ART. Stimulation refers to the use of drugs to stimulate the ovary to develop follicles and oocytes. ART is defined as all treatments or procedures that include the handling of sperm or embryos for the purpose of establishing a pregnancy. This includes but is not limited to IVF, transcervical embryo transfer, GIFT, ZIFT, and TET. ART does not include assisted insemination. Note: Include ALL previous stimulations, even those started at other clinics, regardless of whether the cycle was cancelled. |

Not currently collected
|
New variable. For younger women, prior successful cycles are associated with increased likelihood of success in current cycle. In addition, previous successful IVF is one of the criteria for the use of elective single embryo transfer, which is the best approach for reducing multiple births associated with ART.NOTE: this question will only be shown if 1 or more prior stimulations or frozen cycles are reported.Kalu E, Thum MY, Abdalla H. Prognostic value of first IVF cycle on success of a subsequent cycle.

|
Anti-Mullerian Hormone (AMH) level (ng/mL) |
Add |
Not currently collected |
New variable. Anti-mullerian hormone (AMH) level is a measure of diminished ovarian reserve which predicts pregnancy chances. AMH levels are associated with likelihood of live birth, independent of age. Information on AMH level can therefore provide important information relative to success rates and IVF outcomes in patients with diminished ovarian reserve. Because AMH levels decrease with increasing age, it is necessary to collect the date of the most recent level.

Enter the female patient’s most recent Anti-Mullerian Hormone (AMH) level in ng/mL, if performed within one year of the current ART cycle. Results must be evidenced by a laboratory report (from your clinic, another clinic or a third party laboratory). Please note that if the patient’s AMH level was less than the minimum the lab reports as a value (e.g. the lab reports all values less than 0.16 ng/mL as <0.16), then enter that minimum (e.g. 0.16)
If AMH testing for this patient has never been performed, select unknown.
Enter the date of the most recent AMH level. |

Pregnancy carrier |
Modify |
Intended transfer method: Gestational carrier (yes/no).
Gestational carrier is a woman who gestates an embryo that did not develop from her egg with the expectation of returning the infant to its intended parents. |
Question was revised slightly to include options for patient, gestational carrier or none (e.g., oocyte or embryo banking cycle). The instructions were revised to note that 2 cycles should be reported if both the patient and a gestational carrier are used.
This is similar to question #9 which collects information on intended pregnancy carrier. This question collects information on actual pregnancy carrier, which could change during the course of treatment. |
Indicate whether the intended carrier for this cycle is the patient, a gestational carrier (a woman who gestates an embryo that did not develop from her oocyte, with the expectation of returning the infant to its intended parent(s)), or none (in the case of cycles only intended for oocyte or embryo banking). NOTE: if the intended carrier is a patient and gestational carrier, 2 cycles should be reported . For female same sex couples, the woman who will carry the pregnancy should be identified as the patient. |

Hispanic or Latino ethnicity should be self-reported by the patient, and refers to anyone born in or having ancestors from Spain or one of the western hemisphere countries or territories where Spanish is the primary language (e.g., Mexico, Puerto Rico, Nicaragua, El Salvador, Dominican Republic, Columbia, Peru, Chile). |
Question was revised to include all options for pregnancy carrier (e.g., patient or gestational carrier). The collection of information on race/ethnicity of pregnancy carriers is important for the following reasons: (1) Response to treatment and corresponding success rates may differ among racial/ ethnic groups.(2) There is relatively little valid data on racial/ethnic trends and disparities in ART use and outcomes.(3) Recent studies have indicated racial and ethnic disparities in preterm birth among pregnancies conceived by ART. We also eliminated the “not ascertained by clinic” option since it was redundant with the “unknown” option.
NOTE: if pregnancy carrier is patient and the patient’s oocytes were used, this question will not be shown (race/ethnicity are collected in previous question on oocyte source)

Indication for ICSI |
Add |
Not currently collected |
ICSI has been shown to be safe and effective for overcoming male factor infertility. However, there is evidence of increasing rates of ICSI use for other indications, despite a lack of evidence of improved clinical outcomes. Furthermore, the safety of ICSI in these situations has not been established. Thus it is important to collect information on the indication for use of ICSI in ART cycles.

This question was previously a choice in another question on study types in research cycles (currently #53A). Although still experimental, use of in vitro maturation (IVM) is becoming increasingly common particularly among women with polycystic ovary syndrome; however, there is controversy regarding which IVM methods produce the best fertilization and pregnancy rates. To better monitor the use of this developing technology, we opted to include this as a separate question.

2PN refers to the stage of embryo development that typically occurs 1 day after sperm is added to the egg. The total number of 2PN embryos can be used to calculate fertilization rates, compare the effectiveness of IVF procedures, and evaluate oocyte and sperm factors contributing to infertility. In addition, some clinics use a threshold based on total 2PN as a selection criteria for good prognosis patients.

Question was revised to add a category for elective gender determination and remove unknown option.
Gender determination via PGS can be conducted for medical (avoid disease transmission) and non-medical (sex preference of parents) reasons. In 2008, approximately 4% of ART cycles in the U.S. used PGS and there was a 5% increase in the use of PGS for elective sex selection from 2007-2008. Thus, surveillance of utilization and trends of elective gender determination is warranted.

New question. PGD/PGS results can be affected by misdiagnosis due to the genetic testing processes employed. Embryo misdiagnosis can occur due to possible discordance of chromosomal composition of biopsied cell and remainder of embryo or may occur with mosaicism of aneuploid and euploid cell lines in the same embryo. Given the risks of misdiagnosis and that PGD/PGD is being increasingly incorporated into routine IVF treatments, it is important to collect information pertaining to the types of techniques used for PGD/PGS.

Indicate the PGD or PGS screening technique. Polar Body Biopsy Blastomere Biopsy Blastocyst Biopsy Unknown
Polar body biopsy: Polar bodies are the by-products of egg division. These cells do not serve any role for the egg or embryo and will naturally degrade; however, they can be removed and tested to determine the genetic status of the egg. Polar body testing only tests for the maternal genetic contribution to the embryo. Polar body biopsy occurs at the Day 0 and/or Day 1 stage. Both polar bodies must be removed and tested in order to make an accurate diagnosis.
Blastomere biopsy: Blastomeres are cells from the Day 3 cleavage stage embryo, when approximately 6-8 cells are present. Each blastomere contains both maternal and paternal genetic information.
Blastomere biopsy is the most common method of PGD testing, and involves the removal of one of these cells at the Day 3 stage. Since chromosomal mosaicism is highest at the Day 3 stage, blastomere testing may not always be representative of the genetic content of the embryo. Blastocyst/Trophectoderm biopsy: A blastocyst is a Day 5/6 embryo which contains two cell types – the inner cell mass, which eventually develops into fetal tissues, and the trophectoderm, which gives rise to the developing placenta and other “extra-embryonic” tissues. Blastocyst biopsy involves the removal of a small number of trophectoderm cells for genetic testing. Testing the embryo at this stage has the advantage of reduced chromosomal mosaicism as well as improved DNA amplification, and therefore, improved test accuracy.

This question was added because embryo selection is one of the most important steps in determining IVF outcome. Embryo quality (as determined by morphology) is highly correlated with implantation rates and pregnancy outcome. Furthermore, clinicians routinely use this information when determining the number of embryos to transfer; therefore there is an association between embryo quality and multiple pregnancy rates.

Date of oocyte retrieval (thawed embryos) |
Add |
Not currently collected |
This question was added in order to facilitate the linking of oocyte or embryo banking cycles with outcomes for more accurate calculation of success rates. Recently, there has been an increasing trend of short-term embryo banking (cycles in which all embryos are created with the intent of cryopreservation for subsequent transfer in frozen/thawed cycle(s) in the next few months). Because these cycles do not result in an outcome, they are not included in the overall success rates for ART. There is some evidence that clinics may be encouraging poor prognosis patients to undergo multiple banking cycles in an effort to accumulate embryos and to facilitate the selection of the best embryos for transfer. A result of this trend is that clinics using this practice have inflated success rates because the “accumulation” cycles are not reported. In an effort to address this issue, CDC hopes to link oocyte or embryo banking cycles with subsequent frozen/thawed cycles to more accurately calculate success rates. Thus collection of information on oocyte retrieval date is needed to enable this linkage to occur.

Indicate whether infant was live birth, stillbirth, neonatal death or unknown
A fetus is considered liveborn if it showed signs of life after the complete expulsion or extraction from its mother. Signs of life include breathing, beating of the heart, pulsation of the umbilical cord, or definite movement of the voluntary muscles. Heartbeats are to be distinguished from transient cardiac contractions; respirations are to be distinguished from fleeting respiratory efforts or gasps. The above definition for livebirth is currently used by all 50 states in the US . For practical purposes, a live birth is a birth for which a certificate of live birth was filed. |

Not currently collected |
New question added to evaluate potential intrinsic perinatal risks associated with ART procedures.
Note: questions on births will only be shown for cycles where birth outcome reported as liveborn or stillborn infant(s)
|
For each liveborn infant, indicate if neonatal death occurred. Neonatal death is the death of a liveborn infant before completion of the 28th day of life. If infant survival is unknown, select Unknown. |

Lab Upper Normal Limit for that FSH level |
Drop |
Lab upper normal FSH (lUs): Enter the upper limit of the laboratory's normal range if known. |
Question deleted. Information is not relevant due to discrepancies in how upper limits may be defined. Specifically, the upper range of normal should be based on age of the patient; in addition, most lab assays are accurate to very high numbers. (FSH of 9 is normal in a 42 year old but represents DOR in a 22 year old) |

FSH Unknown |
Drop |
FSH unknown: FSH (follicle stimulating hormone) is a gonadotropin hormone produced and released from the pituitary that stimulates the ovary to ripen a follicle for ovulation. Check this box if FSH testing for this patient was never performed, or if the FSH level is not known |
Question deleted and “unknown” added as an option to the patient maximum FSH question. |

Patient Maximum Estradiol Level |
Drop |
Estradiol (E2) – the predominant estrogen hormone produced by the ovary that has several activities important for reproduction. An elevated serum estradiol level in the early follicular phase of a woman’s menstrual cycle may indicate diminished ovarian reserve. |
Question deleted due to due to potential variations in estradiol (E2) levels. For example, patients often receive exogenous E2 priming leading up to gonadotropin initiation, thus E2 may be falsely elevated at baseline. E2 also varies widely through the menstrual cycle. |

|
|
Lab Upper Normal Limit for that Estradiol Level |
Drop |
|
Question removed because it is not a useful variable. Labs can measure E2 to very high levels by diluting. An elevated E2 during early follicular phase can suggest DOR due to early follicular recruitment and be associated with a falsely suppressed FSH when measured simultaneously in individual patients. It does not make sense to use it for national surveillance since much better markers of ovarian reserve are available – AMH, antral follicle counts, etc. |

Number of Fresh Embryos Transferred to Fallopian Tubes |
Drop |
Number of EMBRYOS: FRESH Transfers to Fallopian Tubes: Enter the number of fresh embryos transferred to the fallopian tubes, or “0” to indicate that none were successfully transferred. Do not leave this variable blank if the transfer of fresh embryos to the fallopian tubes was attempted. Include the number of zygotes transferred to fallopian tubes if zygote intrafallopian transfer (ZIFT) was the method of transfer for this cycle. Record the number of early stage embryos transferred if tubal embryo transfer (TET) was used in this cycle. |
This question was deleted. All questions on transfers to fallopian tubes (oocytes and fresh or frozen embryos) were combined into one question. GIFT, ZIFT and TET are rare; thus it was determined that this information could be combined. |
N/A |
|
|
Number of Thawed Embryos Transferred to Fallopian Tubes |
Drop |
Number of EMBRYOS: THAWED Transfers to Fallopian Tubes: Enter the number of thawed embryos transferred to the fallopian tubes, or “0” to indicate that none were successfully transferred. Include the number of thawed zygotes transferred to fallopian tubes if zygote intrafallopian transfer (ZIFT) was the method of transfer for this cycle. Also, include any zygotes that were produced from thawed oocytes and sperm. Record the number of thawed early stage embryos transferred if tubal embryo transfer (TET) was used in this cycle |
This question was deleted. All questions on transfers to fallopian tubes (oocytes and fresh or frozen embryos) were combined itno one question. GIFT, ZIFT and TET are rare; thus it was determined that this information could be combined. |

Surgical Sterilization—Patient or Partner |
Drop |
Surgical Sterilization – patient or partner: Select the appropriate response from the drop- down list based on the guidelines below. Neither patient nor partner: Neither the patient nor the partner has undergone an operative procedure for the purpose of termination of fertility without reversal. Yes, patient: The patient has undergone an operative procedure for the purpose of termination of fertility without reversal. Surgical sterilization includes tubal ligation or hysterectomy, for the purpose of termination of fertility, without reversal. Yes, partner: The partner has undergone an operative procedure, such as a vasectomy, for the purpose of termination of fertility, without reversal. Both patient and partner: Both the patient and partner have undergone operative procedures for the purpose of termination of fertility without reversal (described above). Patient does not know: The patient cannot recall the reason for undergoing a procedure resulting in termination of fertility, and/or does not know if her partner has undergone a procedure described above. |
This question was removed and surgical sterilization was added as an option for “reason for ART” |

Was an Ultrasound Performed? |
Drop |
If pregnant, was ultrasound performed: Click on either “Yes” or “No” to indicate if an ultrasound was performed. |
The option of “no ultrasound performed” was added to the question on the number of fetal hearts on first ultrasound. Therefore there was no need for this question. |
