Meeting the demand for fertility services: the present and future of reproductive endocrinology and infertility in the United States.

The field of reproductive endocrinology and infertility (REI) is at a crossroads; there is a mismatch between demand for reproductive endocrinology, infertility and assisted reproductive technology (ART) services, and availability of care. This document's focus is to provide data justifying the critical need for increased provision of fertility services in the United States now and into the future, offer approaches to rectify the developing physician shortage problem, and suggest a framework for the discussion on how to meet that increase in demand. The Society of REI recommend the following: 1.

The impact of the Dobbs decision on in-vitro fertilization and fertility care.

Purpose Of Review: The 2022 Supreme Court ruling in Dobbs vs Jackson marks a frightening new reality in America. Physicians and patients have been left confused and concerned regarding the broader implications of this ruling. Now that the constitutional right to an abortion has been overturned and the power has been relinquished to individual states, there is justifiable concern regarding the impact on in-vitro fertilization (IVF).

At its core, health systems science describes the intricate details required to provide high-quality care to individual patients by assisting them in navigating the multifaceted and often complicated US healthcare delivery system. With advances in technology, informatics, and communication, the modern physician is required to have a strong working knowledge of health systems science to provide effective, low-cost, high-quality care to patients.

GnRH receptor-activating autoantibodies in polycystic ovary syndrome: identification of functional epitopes and development of epitope mimetic inhibitors.

Purpose: We have recently demonstrated that gonadotrophin-releasing hormone receptor-activating autoantibodies (GnRHR-AAb) are associated with polycystic ovary syndrome (PCOS). The aim of this study was to map the antigenic epitopes of GnRHR-AAb from PCOS patients, and develop retro-inverso peptide inhibitors that specifically target GnRHR-AAb.

Methods: Serum samples from ten GnRHR-AAb-positive PCOS patients and ten GnRHR-AAb-negative healthy controls were tested.

Relationship between semen regurgitation and pregnancy rates with intrauterine insemination.

Objective: To evaluate the relationship between semen regurgitation and intrauterine insemination (IUI) outcomes. We hypothesized that clinical pregnancy rates and live birth rates would be reduced when regurgitation occurred.

Design: Retrospective cohort study.

Elevated activity levels of activating autoantibodies to the GnRH receptor in patients with polycystic ovary syndrome.

Objectives: 1) To confirm the correlation of GnRH receptor (GnRHR) activating autoantibody (AAb) activity with polycystic ovary syndrome (PCOS) diagnosis in large well defined cohorts; and 2) to evaluate suppression of AAb activity with GnRH antagonist medication in transfected GnRHR cells exposed to serum of PCOS patients.

Design: Cross-sectional matched case-control study.

Setting: University-based research facility.

Increased testosterone and proinflammatory cytokines in patients with polycystic ovary syndrome correlate with elevated GnRH receptor autoantibody activity assessed by a fluorescence resonance energy transfer-based bioassay.

Purpose: The recently identified agonistic autoantibodies (AAb) to the gonadotropin-releasing hormone receptor (GnRHR) are a novel investigative and therapeutic target for polycystic ovary syndrome (PCOS). In this study, we used a new cell-based fluorescence resonance energy transfer (FRET) bioassay to analyze serum GnRHR-AAb activity and examine its relationship with testosterone and proinflammatory cytokines in patients with PCOS.

Methods: Serum samples from 33 PCOS patients, 39 non-PCOS ovulatory infertile controls and 30 normal controls were tested for GnRHR-AAb activity and proinflammatory cytokines in a FRET-based bioassay and multiplex bead-based immunoassay, respectively.

Gonadotrophin-releasing hormone receptor autoantibodies induce polycystic ovary syndrome-like features in a rat model.

New Findings: What is the central question of this study? Is there a causal relationship between gonadotrophin-releasing hormone (GnRH) receptor-activating autoantibodies and polycystic ovary syndrome (PCOS)? What is the main finding and its importance? Induction of GnRH receptor-activating autoantibodies in rats resulted in increased luteinizing hormone pulsatility and testosterone concentrations, disrupted oestrous cycles, increased atretic follicles, and activation of insulin signalling in the pituitary and ovary. These changes replicate those seen in humans with PCOS, suggesting that GnRH receptor-activating autoantibodies might be involved in the pathogenesis of PCOS.

Abstract: Gonadotrophin-releasing hormone receptor-activating autoantibodies (GnRHR-AAb) are associated with polycystic ovary syndrome (PCOS).

Autoimmune activation of the GnRH receptor induces insulin resistance independent of obesity in a female rat model.

Polycystic ovary syndrome (PCOS), a metabolic and reproductive disease, is frequently associated with type 2 diabetes. We have demonstrated activating autoantibodies (AAb) directed toward the second extracellular loop (ECL2) of the gonadotropin-releasing hormone receptor (GnRHR) are present in a significant subgroup of PCOS patients. It is unclear whether GnRHR-AAb can induce peripheral tissue insulin resistance (IR) in animal models.

The Role of GnRH Receptor Autoantibodies in Polycystic Ovary Syndrome.

Objective: Is polycystic ovary syndrome (PCOS) associated with activating autoantibodies (AAb) to the second extracellular loop (ECL2) of gonadotropin-releasing hormone receptor (GnRHR)?

Design And Methods: We retrospectively screened sera from 40 patients with PCOS and 14 normal controls (NCs) with regular menses using enzyme-linked immunosorbent assay (ELISA) for the presence of GnRHR-ECL2-AAb. We obtained similar data from 40 non-PCOS ovulatory but infertile patients as a control group (OIC) of interest. We analyzed GnRHR-ECL2-AAb activity in purified immunoglobulin (Ig)G using a cell-based GnRHR bioassay.

Does the ultrasound appearance of the endometrium during treatment with assisted reproductive technologies influence pregnancy outcomes?

We evaluated endometrial pattern, defined as the relative echogenicity of the endometrium on a longitudinal uterine ultrasonic section, as a surrogate for endometrial receptivity in an attempt to evaluate the association between endometrial pattern and pregnancy outcome in women who underwent ART treatment. The primary outcome was live birth and secondary outcomes were clinical intrauterine pregnancy and miscarriage. Potential associations were evaluated using cluster-weighted generalized estimating equations to account for within-couple correlation among repeated ART cycles while adjusting for potentially confounding variables.

Developing as an Academic Medical Educator in Obstetrics and Gynecology.

The lack of a defined framework for advancement and development of professional identity as a medical educator may discourage faculty from pursuing or progressing through a career in academic medical education. Although career advancement has historically been linked to clinical work and research, promotion for teaching has not been supported at the same level. Despite potential challenges, a career in academic medicine has its share of rewards.
