Patient and cycle characteristics summarize the types of ART services performed and the kinds of patients who received ART procedures. Please note patient characteristics are presented per cycle rather than per patient. As a result, patients who had more than one ART cycle within the reporting year are represented more than once.

Because a woman's fertility declines with age, ART data are reported separately by age group. You may wish to find a clinic that commonly sees patients your age.

An intended egg retrieval is ART cycle that starts with the intent to retrieve eggs. If eggs are retrieved, it may take one or more transfers to achieve live birth. The cumulative (or combined) chance of a live birth delivery typically increases with each additional egg or embryo transfer because it provides another opportunity to conceive a child. Displayed below are cumulative percentages of intended egg retrievals that resulted in a live birth delivery after all associated egg or embryo transfers within 12 months of cycle start. A live birth delivery is the delivery of one or more infants (e.g. single, twins, triplets) with any signs of life.

DISCLAIMER: Patient medical characteristics, such as age, diagnosis, and ovarian reserve, affect the success of ART treatment. Comparison of success rates across clinics may not be meaningful due to differences in patient populations and ART treatment methods. The success rates displayed here do not reflect any one patient’s chance of success. Patients should consult with a doctor to understand their chance of success based on their own characteristics.

^a Numbers and percentages exclude 0 cycle(s) that were evaluating new procedures.
^b Fractions are used when the denominator is less than 20; * Reported sample size of 1 through 4 have been suppressed.
^c A live birth is defined as the delivery of one or more infants with any sign of life. Multiple-infant births (for example, twins) with at least one live born infant are counted as one live birth. Success rates for cycles using a patient’s own eggs are calculated by using all cycles started in 2017 with the intent to retrieve a patient’s eggs and all transfers of these eggs, or embryos created from these eggs, started within 12 months of the start of the retrieval cycle. Success rates for cycles using a donor’s eggs or donated embryos are calculated by using all transfers started in 2018.
^d Patients of all ages are combined because previous data show that a patient’s age does not substantially affect success when using a donor’s eggs or donated embryos.
^e Includes: (1) all cycles started with the intent to freeze all resulting eggs or embryos in which no eggs were retrieved or no eggs or embryos were actually frozen; (2) all cycles started with the intent to transfer fresh eggs, or fresh embryos created from fresh eggs, that were not cancelled and in which no eggs or embryos were actually transferred; and, (3) all cycles started with the intent to transfer frozen eggs or frozen embryos in which no eggs or embryos were actually transferred.
^fPercentages may add to more than 100% because more than one diagnosis can be reported for each ART cycle.

Description of Services and Profile

Description of Services and Profile
ART for single women	ART for single women is when ART treatment is performed for women who report that they are unmarried.
Donor egg services	A donor egg cycle occurs when an embryo is formed from the egg of one woman (the donor) and is transferred to another woman (the recipient).
Donor embryo services	A donor embryo is an embryo that is donated by a patient or couple who previously underwent ART treatment and had extra embryos available.
Embryo cryopreservation services	Cryopreservation is the practice of freezing embryos for potential future use.
Egg cryopreservation services	Cryopreservation is the practice of freezing eggs for potential future use.
Gestational carrier services	A gestational carrier or surrogate is a woman who gestates, or carries, an embryo that was formed from the egg of another woman. The surrogate usually has a contractual obligation to return the infant to its intended parents.
SART member	The Society of Assisted Reproductive Technology (SART) is an affiliate of the American Society for Reproductive Medicine (ASRM) and is a professional society composed of clinics and programs that provide ART.
Verified lab accreditation	A “Yes” indicates the clinic had an embryo laboratory accreditation at the time of reporting by at least one of specified accrediting organizations.

Clinic Summary

Description of Clinic Summary
Total cycles	Because ART consists of several steps, an ART procedure is typically referred to as a cycle of treatment rather than a procedure at a single point in time. The start of an ART cycle is usually when a woman begins taking medication to stimulate egg production or begins monitoring with the intent of having embryos transferred. This is the number of ART cycles started. The total number of ART cycles is calculated as the sum of (1) the number of cycles started with the intent to freeze all resulting eggs or embryos (for example, short term banking or fertility preservation); (2) the number of cycles started with the intent to transfer fresh or frozen eggs retrieved from either the patient or donor; and (3) the number of cycles started with the intent to transfer fresh or frozen embryos created from fresh or frozen eggs retrieved from either the patient or donor.
Fertility Preservation cycles	The number of cycles started with the intent of freezing and banking all eggs or embryos for at least 12 months for future use; * Reported sample size of 1 through 4 have been suppressed.
Pregnancies	The total number of pregnancies that resulted from ART cycles. Because some pregnancies end in a miscarriage or stillbirth, the number of pregnancies may be higher than the number of deliveries or infants born.
Deliveries	The total number of live birth deliveries of infants conceived with the help of ART. One delivery could result in one or more infants born.
Total infants born	The total number of ART-conceived infants born, including single infants and infants born in a multiple birth delivery (e.g., twins, triplets).

Filter & Description &

Filter and Description
Filter	Description
No filter	Multiple female factor infertility is a diagnostic category used when more than one female cause of infertility but no male factor infertility is diagnosed.
Male factor	Male factor infertility refers to any cause of infertility due to low sperm count or problems with sperm function that makes it difficult for a sperm to fertilize an egg under normal conditions.
Endometriosis	Endometriosis is a medical condition that involves the presence of tissue similar to the uterine lining in abnormal locations. This condition can affect both fertilization of the egg and embryo implantation.
Tubal factor	Tubal factor infertility is a diagnostic category used when the woman’s fallopian tubes are blocked or damaged, making it difficult for the egg to be fertilized or for an embryo to travel to the uterus.
Ovulatory dysfunction	Ovulatory dysfunction is a diagnostic category used when a woman’s ovaries are not producing eggs normally. It includes polycystic ovary syndrome and multiple ovarian cysts.
Uterine factor	Uterine factor infertility is a structural or functional disorder of the uterus that results in reduced fertility.
Diminished ovarian reserve	Diminished ovarian reserve means that the ability of the ovary to produce eggs is reduced. Reasons include congenital, medical, or surgical causes or advanced age.
Recurrent pregnancy loss	Other causes of infertility include immunological problems, chromosomal abnormalities, cancer chemotherapy, and serious illnesses.
Unexplained factor	Unknown cause of infertility is a diagnostic category used when no cause of infertility is found in either the woman or the man.

Patients using their own eggs	Own ART cycles are those cycles in which a woman's own embryos are transferred to the woman.
