Research objectiveAmong singleton live births resulting from donor oocyte cycles, do perinatal outcomes differ between single (SET) and double embryo transfers (DET)?MethodsWe utilized a retrospective cohort of 610 recipients who had a sing…

Many endocrine-disrupting chemicals have been linked to impaired ovarian function and fertility. However, most research has focused on small numbers of known chemicals in blood or urine. We aimed to measure the untargeted chemical exposome …

ObjectiveTo describe characteristics, trends, and outcomes of international gestational surrogacy cycles in the United States (US).DesignRetrospective cohort study.SettingAll assisted reproductive technology cycles in the US reported to the…

ObjectiveTo determine factors associated with a positive male patient experience (PMPE) at fertility clinics among male patients.DesignCross-sectional study Setting: Not applicable Patients: Male respondents to the FertilityIQ questionnaire…

Ovarian reserve is an important determinant of a woman's reproductive potential, and women with diminished ovarian reserve (DOR) often seek in vitro fertilization (IVF). The underlying etiology of DOR is unknown, but follicular fluid cytoki…

PurposeTo report fertility treatment use and outcomes among patients who use donor sperm for intrauterine insemination (IUI), in vitro fertilization (IVF), and reciprocal IVF (co-IVF).MethodsThis is a retrospective review of patients who us…

PurposeOocyte donor in vitro fertilization (IVF) represents an ideal model to study the effects of embryo stage on reproductive success, as embryos come from young women with high-quality oocytes. Our study aimed to determine if embryo tran…

PurposeThe 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 elec…

BackgroundInformation regarding the use of donor sperm in assisted reproductive technology, as well as subsequent treatment and perinatal outcomes, remains limited. Outcome data would aid patient counseling and clinical decision making.Obje…

PurposeThe 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.MethodsWe used autologous IVF cycl…

ObjectiveTo describe the relationship between severe diminished ovarian reserve (DOR) and assisted reproductive technology outcomes.Study designRetrospective cohort including all United States’ fertility centers reporting to the CDC Nationa…

BackgroundLimited 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 decisi…

ObjectiveTo investigate the associations among underweight body mass index (BMI), pregnancy, and obstetric outcomes among women using assisted reproductive technology (ART).DesignRetrospective cohort study using national data and log binomi…

ObjectiveTo 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.DesignRetrospective cohort s…

Anti-Müllerian hormone (AMH) has potential local effects on ovarian function and endometrial tissue, including endometriosis, but its presence in peritoneal fluid is not fully understood. This is a cross-sectional study evaluating AMH in pe…
