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…
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 (…
OBJECTIVE: To describe the relationship between severe diminished ovarian reserve (DOR) and assisted reproductive technology outcomes. STUDY DESIGN: Retrospective cohort including all United States’ fertility centers reporting to the CDC N…
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 investigate the associations among underweight body mass index (BMI), pregnancy, and obstetric outcomes among women using assisted reproductive technology (ART). DESIGN: Retrospective cohort study using national data and log …
PURPOSE: The aim of this study was to identify factors associated with double embryo implantation following double embryo transfer (DET) during assisted reproductive technology (ART) procedures and to evaluate the implications of findings i…
OBJECTIVE: To characterize risks for early pregnancy loss after fresh and frozen IVF cycles and to investigate whether risk is modified by infertility diagnoses or transfer of embryos in fresh versus frozen cycles. DESIGN: Retrospective co…
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…
STUDY QUESTION: Are assisted reproductive technology (ART) treatment factors or infertility diagnoses associated with autism among ART-conceived children? SUMMARY ANSWER: Our study suggests that the incidence of autism diagnosis in ART-con…
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 endometriosis-associated infertility trends among assisted reproductive technology (ART) cycles, and to compare cancellation and hyperstimulation risks and pregnancy and live birth rates among women using ART for endome…
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…
ImportanceIntracytoplasmic sperm injection (ICSI) is increasingly used in patients without severe male factor infertility without clear evidence of a benefit over conventional in vitro fertilization (IVF).ObjectiveTo assess national trends …
ObjectiveTo assess trends and outcomes of assisted hatching among assisted reproductive technology (ART) cycles.DesignRetrospective cohort analysis using National ART Surveillance System (NASS) data.SettingU.S. fertility centers reporting t…
OBJECTIVE: To assess the association between number of embryos transferred and a measure of assisted reproductive technology success that emphasizes good perinatal outcome. METHODS: We analyzed assisted reproductive technology cycles initi…
OBJECTIVE: To assess trends in elective single ET and identify factors associated with a good perinatal outcome. DESIGN: Retrospective cohort study. SETTING: Clinic-based data. PATIENT(S): A total of 886,686 fresh, nondonor cycles report…
IMPORTANCE: The prevalence of oocyte donation for in vitro fertilization (IVF) has increased in the United States, but little information is available regarding maternal or infant outcomes to improve counseling and clinical decision making.…
OBJECTIVE: To estimate trends in good perinatal outcomes (singleton live births at term with birthweight more than 2,500 g) among live births after assisted reproductive technology in the United States from 2000 to 2008, and associated fact…
