Purpose: To characterize the likelihood of cryopreserving enough oocytes for 50%, 60%, or 70% estimated live birth rate (eLBR) with 1-2 planned oocyte cryopreservation (Pl-OC) cycles.

Methods: We performed a retrospective cohort study utilizing all patients completing ≥ 1 Pl-OC cycle from 2016 to 2018 at a large single-center OC program. Subjects were categorized by age at retrieval and number of cycles.

Background: Over one million Americans are infected with HIV, and approximately 300,000 are women. Overall health in HIV infected persons has improved, and many seropositive women desire children. This study describes the reproductive outcomes of HIV seropositive women treated by assisted reproduction at our center and compares their clinical results with age-matched HIV seronegative controls.

Purpose: To evaluate the effect of adjunctive letrazole or clomiphene in IVF stimulation protocols.

Methods: A retrospective analysis of high dose GnRH antagonist IVF cycles (450-600 IU of gonadotropins) that have met poor responder criteria. Selected consecutive cycles in same patients differed solely in presence or absence of adjunctive clomiphene or letrazole.

While the age of a donor is a fundamental factor to the success of donor IVF, no serum markers have been demonstrated to be useful in predicting variability of ovarian response in individual donors. Anti-Müllerian hormone (AMH) has been described as an accurate marker of ovarian response in patients undergoing IVF, but has not been applied to oocyte donors. AMH concentrations from 104 anonymous oocyte donors between the ages of 21-32 years were studied and IVF outcome parameters compared.

The conflicting results from studies on the predictive capabilities of serum anti-Müllerian hormone (AMH) for IVF pregnancy outcomes may be attributed to small sample sizes and disparities in the age of the study populations. The relationship between AMH and IVF pregnancy outcomes was clarified with retrospective cross-tabulation analyses (n=1558) stratified by age to control for its confounding effects. Serum AMH concentrations were divided into tertiles (≤ 0.

Nearly 130,000 American women are human immunodeficiency virus (HIV) seropositive. The present study sought to establish a comprehensive programme to address their fertility needs in order to minimize infectious, medical and reproductive risks to prospective patients. Forty women, aged 27-42 years, were evaluated.

Gynaecologists are familiar with occluded Fallopian tubes presenting as pelvic masses on ultrasound. However, it is important to also consider anomalies of the urinary collecting system when presented with a pelvic mass, some of which do not necessitate surgical therapy. This report describes the case of a woman with unknown and asymptomatic bilateral megaureters who presented for evaluation of infertility.

Background: Cervical ectopic pregnancy accounts for less than 1% of all ectopic gestations. The most effective, fertility sparing treatment of a cervical ectopic pregnancy is still unclear due to limited reported experience.

Case: The diagnosis and management of a 32-year-old with a cervical ectopic pregnancy after in vitro fertilization and embryo transfer is described.

Objective: To review 10 years of experience providing fertility care to men seropositive for human immunodeficiency virus (HIV) using sperm washing and in vitro fertilization with intracytoplasmic sperm injection (IVF-ICSI).

Design: Retrospective study.

Setting: University-based practice.

Objective: To determine whether the decline in pregnancy and implantation rates in repeated fresh IVF cycles is associated with the availability of embryo cryopreservation.

Design: Retrospective study.

Setting: Assisted reproductive unit at an academic institution.

Cinnamon extract has been shown to reduce insulin resistance in in vitro and in vivo studies by increasing phosphatidylinositol 3-kinase activity in the insulin signaling pathway and thus potentiating insulin action. Fifteen women with polycystic ovary syndrome (PCOS) were randomized to daily oral cinnamon and placebo for 8 weeks. Comparisons of post-treatment to baseline insulin sensitivity indices using fasting and 2-hour oral glucose tolerance tests showed significant reductions in insulin resistance in the cinnamon group but not in the placebo group.

Objective: This study determines whether pretreatment levels of müllerian inhibiting substance/antimüllerian hormone (MIS/AMH) would reflect ovarian response to exogenous gonadotropin in women with polycystic ovary syndrome (PCOS) and ovulatory controls matched by age and weight.

Study Design: Case-control study of 20 women with PCOS and 10 normoovulatory women undergoing controlled ovarian hyperstimulation (COH) for in vitro fertilization (IVF) at an academic medical center.

Results: Baseline serum MIS/AMH levels in PCOS were higher than those of normoovulatory women (P < .
