Purpose: This study is to evaluate duration of oocyte cryostorage and association with thaw survival, fertilization, blastulation, ploidy rates, and pregnancy outcomes in patients seeking fertility preservation.

Methods: Retrospective cohort study to evaluate clinical outcomes in patients who underwent fertility preservation from 2011 to 2023 via oocyte vitrification for non-oncologic indications. Primary outcome was thaw survival rate.

Reciprocal in vitro fertilization (IVF) and intravaginal culture (IVC) are two technologies that allow same-sex female couples to jointly contribute biologically to a pregnancy. This systematic review aimed to synthesize the clinical outcomes of each method including live birth rate, clinical pregnancy rate, embryo quality, and perinatal complications. A dual-reviewer protocol identified eight studies on reciprocal IVF and ten studies on IVC.

Purpose: To evaluate the association between spironolactone use and controlled ovarian hyperstimulation (COH) outcomes.

Methods: Retrospective study, including patients who underwent COH. Oocyte yield and maturation rates were compared by categories of spironolactone use at the start of their cycle.

Research Question: Is there any association between pelvic pain and primary caesarean delivery for patients undergoing assisted reproductive technology (ART) treatment?

Design: Retrospective cohort study of nulliparous patients with singleton pregnancies who underwent ART treatment and achieved a live birth between 2012 and 2020. Cases included patients diagnosed with pelvic pain. A 3:1 ratio propensity-score-matched population of patients without a history of pelvic pain was included as the control group.

Purpose: Determine if the gene expression profiles of ovarian support cells (OSCs) and cumulus-free oocytes are bidirectionally influenced by co-culture during in vitro maturation (IVM).

Methods: Fertility patients aged 25 to 45 years old undergoing conventional ovarian stimulation donated denuded immature oocytes for research. Oocytes were randomly allocated to either OSC-IVM culture (intervention) or Media-IVM culture (control) for 24-28 h.

Introduction: Fertility-related concerns cause significant anxiety among patients with Hereditary Breast and Ovarian Cancer Syndrome (HBOC). The Society of Gynecologic Oncology and the American Society for Reproductive Medicine recommend patients diagnosed with HBOC receive early referral to a reproductive endocrinologist. However, evidence about fertility trends in this patient population are limited and guidelines are scarce.

Objective: To evaluate fertility treatment outcomes among transgender (TG) men with a history of gender-affirming hormone therapy with exogenous testosterone.

Design: Descriptive, retrospective cohort study.

Patients: Transgender men with a history of gender-affirming hormone therapy with exogenous testosterone underwent fertility treatments, including embryo cryopreservation, in vitro fertilization (IVF), co-IVF, oocyte cryopreservation, and intrauterine insemination (IUI), between 2013 and 2021.

Article Synopsis
  • The study aimed to examine how maternal outcomes are influenced by twin chorionicity (the type of placentation) in a large group of obstetric patients from 2000 to 2016.
  • Researchers compared outcomes between mothers with monochorionic twins (one placenta) and dichorionic twins (two placentas) by analyzing medical records, excluding certain high-risk cases.
  • Results showed no significant differences in gestational diabetes or hypertensive disorders, but monochorionic twin mothers had significantly lower rates of cesarean deliveries.

Our study aims to assess three self-reported outcomes: (1) comfort of, (2) competency in, and (3) curricular satisfaction of OB-GYN residents in caring for transgender and gender nonconforming (TGNC) patients. This was a cross-sectional survey of a convenience sample of OB-GYN residents consisting of 28 questions on a 4-point Likert scale. The survey was distributed to OB-GYN residents via residency program directors and coordinators.

We sought to identify factors associated with disparities in tamoxifen utilization among young patients at high-risk for developing breast cancer. We identified 67 premenopausal, high-risk women age 35-45, without surgical prophylaxis, who did not initiate tamoxifen. Factors associated with noninitiation were examined.

Objective: Use of effective contraception could be one method to decrease recurrent preterm birth by increasing intervals between pregnancies. We assessed correlates of contraceptive counseling and uptake among women who delivered preterm.

Materials And Methods: This is a retrospective cohort study of women who delivered live-born singletons or twins before 32 weeks' gestation.

Background And Objectives: Breast cancer treatment can cause premature ovarian failure, yet the majority of young cancer patients do not receive adequate education about treatment effects before initiating chemotherapy. We studied the impact of an oncofertility program on access to fertility preservation.

Methods: An oncofertility program was initiated to foster collaboration between oncologists and reproductive endocrinologists, and to help increase access to fertility preservation.

Background: Adjuvant tamoxifen reduces breast cancer recurrence risk and mortality; however, initiation and treatment persistence are poor for younger patients. We hypothesized that a unique set of factors, including fertility concerns, would contribute to the poor tamoxifen use among premenopausal patients.

Methods: From 2007 to 2012, 515 premenopausal patients younger than age 45 years, with stage 0 to III hormone receptor-positive breast cancer, for whom tamoxifen was recommended, were identified.
