Enhanced Ovarian FKBP51 Expression is Associated with Ovarian Aging: A Molecular Insight for Age-Related Fertility in Women.

Objective: To study the relationship between FK506-binding protein 51 (FKBP51) and ovarian aging and/or diminished ovarian reserve (DOR) in human ovaries by comparing FKBP51 levels in granulosa (GC) and cumulus cells (CC), collected during controlled ovarian stimulation (COS) from women of advanced reproductive age and/or with a diagnosis of DOR with that of young women with normal ovarian reserve. To explore the association between increased FKBP51 expression and human ovarian aging further, expression of FKBP51 was compared in ovarian stroma of post-menopausal versus pre-menopausal women. Lastly, this relation was further queried by comparing ovarian expression of several collagen genes as markers of ovarian fibrosis in 14-month-old wild type (Fkbp5) and Fkbp5 knockout (Fkbp5) mice.

Methods: A retrospective cohort analysis on patients undergoing IUI at a large US fertility network. Baseline demographic characteristics, primary infertility diagnoses, and pregnancy outcomes were recorded.

Beyond the surface: Does stage I-II endometriosis impact fertility? Exploring the challenges of mild disease.

Endometriosis is one of the most common gynecologic conditions that women face throughout their lives. Despite advances in technology, diagnosis and treatment of this relapsing and remitting condition is still challenging for many women. This review focuses on literature pertaining to minimal/mild (stage I/II) endometriosis and its impact on fertility.

Objective: To study the effect of adenomyosis on the localized expression of the GATA binding proteins 2 and 6 (GATA2 and GATA6) zinc-finger transcription factors that are involved in proliferation of hematopoietic and endocrine cell lineages, cell differentiation, and organogenesis, potentially leading to impaired endometrial implantation.

Design: Laboratory based experimental study.

Setting: Academic hospital and laboratory.

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.

Live birth per embryo transfer with next generation sequencing preimplantation genetic testing: an analysis of 26,107 cycles.

The technique and platform used for preimplantation genetic testing for aneuploidy (PGT-A) have undergone significant changes over time. The contemporary technique utilizes trophectoderm biopsy followed by next-generation sequencing (NGS). The goal of this study was to explore the role of PGT-A using NGS technique exclusively in contemporary fertilization (IVF) practice.

The effect of trophectoderm biopsy for preimplantation genetic testing on fetal birth weight and preterm delivery.

Background: Preimplantation genetic testing for aneuploidy (PGT-A) is used as part of in-vitro-fertilization (IVF) to assist in selection of euploid embryos, which involves performing trophectoderm biopsy. The effect of possible trauma caused by biopsy and the implication on pregnancy is unknown. Hence, the objective of the study was to determine if embryo biopsy for PGT-A affects birth weight or preterm birth rate.

Live birth associated with peak serum estradiol levels in letrozole intrauterine insemination cycles.

Objective: To identify whether the serum estradiol (E2) level on the day of human chorionic gonadotropin (hCG) trigger or luteinizing hormone (LH) surge (hCG-LH) was associated with the live birth rate (LBR) during ovulation induction (OI) or controlled ovarian hyperstimulation with letrozole followed by intrauterine insemination (IUI).

Design: Retrospective cohort study.

Setting: Large, multicenter private practice.

Oocyte Retrieval in Asymptomatic Patients Positive for SARS-CoV-2.

Objective: To report two cases of oocyte retrieval performed in asymptomatic SARS-CoV-2-positive patients.

Design: Case report. .

FKBP51 Contributes to Uterine Leiomyoma Pathogenesis by Inducing Cell Proliferation and Extracellular Matrix Deposition.

The FK506-binding protein 51 (FKBP51) binds progesterone receptor (PR), glucocorticoid receptor (GR), and androgen receptor (AR) to coregulate their transcriptional activity. We evaluated FKBP51 expression and function in human leiomyoma vs. myometrial tissues and primary cultures to discover FKBP51 role(s) in the pathogenesis of leiomyomas.

Reduction of Heavy Menstrual Bleeding in Women Not Designated as Responders to Elagolix Plus Add Back Therapy for Uterine Fibroids.

To assess outcomes of women with uterine fibroids (UFs) and heavy menstrual bleeding (HMB) treated with 300 mg elagolix twice daily plus add-back therapy (E2 1 mg/NETA 0.5 mg once daily) or placebo who were not considered responders in pooled analysis of two phase 3, 6-month randomized clinical trials (Elaris UF-1 and UF-2). Responders were defined as women who met both primary end point bleeding criteria (<80 mL menstrual blood loss [MBL] during the final month and ≥50% reduction in MBL from baseline to the final month) and either completed the study or discontinued due to predefined reasons.

The role of preimplantation genetic testing for aneuploidy in a good prognosis IVF population across different age groups.

Preimplantation genetic testing for aneuploidy is associated with increased pregnancy success and reduced miscarriage in women 35 years and older when embryos are available for transfer. In this retrospective cohort study our objective was to evaluate if this holds true in good prognosis patients and across all age groups. Data were obtained from the Society for Assisted Reproductive Technology between 2014-2015.

Use of low dose vaginal misoprostol in office hysteroscopy: a pre-post interventional study.

A pre-post interventional study of patients undergoing office hysteroscopy alone and in combination with endometrial biopsy was performed during October 2015-March 2018 to evaluate the effect of low dose vaginal misoprostol on patient's pain. Pain scores were assessed using the visual analog scale at the completion of the procedure. There were 646 patients included in the study.

Catecholestradiol Activation of Adrenergic Receptors Induces Endometrial Cell Survival via p38 MAPK Signaling.

Context: Enhanced levels of catecholestradiols, 2-hydroxyestradiol (2-OHE2) or 4-hydroxyestradiol (4-OHE2), are reported in endometriosis. During gestation, catecholestradiol activation of adrenergic receptors (AR) elevates estrogen receptor (ER)-independent proliferation of uterine arterial endothelial cells.

Objective: To investigate β-AR-mediated catecholestradiol effects on human endometrial stromal cell (HESC) and epithelial cell survival in endometriosis.

Objective: To collect data on the current reproductive endocrinology and infertility (REI) fellowship interview process so that it may be improved in the future.

Design: Web-based cross-sectional survey. In addition, fellowship program directors and coordinators were contacted by e-mail.

Duration of ovarian stimulation is predictive of in-vitro fertilization outcomes.

Background: The aim of this study is to evaluate the effect of ovarian stimulation duration on oocyte/embryo development and pregnancy outcome in an in-vitro fertilization cycle (IVF).

Methods: Retrospective cohort study performed at University of South Florida reproductive center between January 2011 and December 2016. A total of 690 sub-fertile women who underwent autologous IVF cycle were included for analysis.

Contemporary management of adnexa at the time of benign hysterectomy: a review of the literature.

Ovarian cancer is the leading cause of Gynecological cancer related mortality in the USA. Due to the absence of an effective screening method, concomitant adnexal management during hysterectomy or other pelvic surgeries is a prime consideration. Bilateral salpingo-oophorectomy (BSO) offers the benefit of eliminating the risk of ovarian cancer however it leads to surgical menopause with unfavourable overall health outcomes.
