PURPOSE: The majority of data regarding oocyte cryopreservation (OC) outcomes focuses on healthy women. We compare trends, cycle characteristics, and outcomes between women freezing oocytes for fertility preservation due to cancer versus el…
OBJECTIVES: To assess trends, predictors, and perinatal outcomes of ovarian hyperstimulation syndrome (OHSS) associated with in vitro fertilization (IVF) cycles in the United States. DESIGN: Retrospective cohort study using National Assist…
BACKGROUND: Smoking near conception has adverse effects on pregnancy outcomes. We estimated the proportion of assisted reproductive technology (ART) cycles with smoking reported and associated clinical outcomes. METHODS: We used a retrospe…
PURPOSE: In vitro fertilization (IVF) infants have lower birthweights than their peers, predisposing them to long-term health consequences. Blastocyst transfer (BT), at day 5-6 post-fertilization, is increasing in usage, partially due to im…
BACKGROUND: Singleton infants conceived using assisted reproductive technology have lower average birthweights than naturally conceived infants and are more likely to be born low birthweight (<2500 gr). Lower birthweights are associated wit…
OBJECTIVE: To compare indications and trends in intracytoplasmic sperm injection (ICSI) use for in vitro fertilization (IVF) cycles among residents of states with and without insurance mandates for IVF coverage. DESIGN: Cross-sectional ana…
PURPOSE: To compare national trends and perinatal outcomes following the use of ejaculated versus surgically acquired sperm among IVF cycles with male factor infertility. METHODS: This retrospective cohort includes US fertility clinics rep…
PURPOSE: The purpose of this study is to examine the spectrum of infertility diagnoses and assisted reproductive technology (ART) treatments in relation to risk of preterm birth (PTB) in singletons. METHODS: Population-based assisted repro…
OBJECTIVE: To compare characteristics, explore predictors, and compare assisted reproductive technology (ART) cycle, transfer, and pregnancy outcomes of autologous and donor cryopreserved oocyte cycles with fresh oocyte cycles. DESIGN: Ret…
OBJECTIVE: To explore disparities in prematurity and low birth weight (LBW) by maternal race and ethnicity among singletons conceived with and without assisted reproductive technology (ART). METHODS: We performed a retrospective cohort stu…
PURPOSE: The purpose of the study was to describe trends in and investigate variables associated with clinical pregnancy and live birth in autologous in vitro fertilization (IVF) cycles among women ≥40 years. METHODS: We used autologous IV…
OBJECTIVE: To examine outcomes of singleton pregnancies conceived without assisted reproductive technology (non-ART) compared with singletons conceived with ART by elective single-embryo transfer (eSET), nonelective single-embryo transfer (…
IMPORTANCE: Use of assisted reproductive technology (ART) has been associated with increased risks for birth defects. Variations in birth defect risks according to type of ART procedure have been noted, but findings are inconsistent. OBJEC…
OBJECTIVE: To explore whether recently enacted infertility mandates including coverage for assisted reproductive technology (ART) treatment in New Jersey (2001) and Connecticut (2005) increased ART use, improved embryo transfer practices, a…
OBJECTIVE: To assess treatment and pregnancy/infant-associated medical costs and birth outcomes for assisted reproductive technology (ART) cycles in a subset of patients using elective double embryo (ET) and to project the difference in cos…
BACKGROUND: Limited published data exist detailing outcomes of donor embryo cycles. Patients and clinicians would benefit from information specific to donor embryo cycles to inform fertility treatment options, counselling, and clinical deci…
OBJECTIVE: To assess the characteristics of IVF cycles for which preimplantation genetic diagnosis (PGD) was used and to evaluate indications for PGD and treatment outcomes associated with this procedure as compared with cycles without PGD …
OBJECTIVE: To evaluate trends and reproductive outcomes of gestational surrogacy in the United States. DESIGN: Retrospective cohort study. SETTING: Infertility clinics. PATIENT(S): IVF cycles transferring at least one embryo. INTERVENTI…
OBJECTIVE: To use linked assisted reproductive technology (ART) surveillance and birth certificate data to compare ET practices and perinatal outcomes for a state with a comprehensive mandate requiring coverage of IVF services versus states…
OBJECTIVE: To assess national trends in ectopic pregnancy incidence among assisted reproductive technology users and identify risk factors associated with ectopic pregnancy. METHODS: We identified 553,577 pregnancies reported to the Nation…
OBJECTIVE: To evaluate trends of monozygotic twinning after single embryo transfer and its association with patient and treatment factors. METHODS: Our retrospective cohort study included 28,596 pregnancies after fresh, nondonor single emb…
