Fresh vs. frozen: pregnancy outcomes and treatment efficacy between fresh embryo transfer vs. untested freeze-all cycles.

Objective: To compare pregnancy outcomes after single blastocyst embryo transfer among patients whose first autologous embryo transfer was either a fresh embryo transfer or a frozen embryo transfer (FET) after a freeze-all, in the absence of preimplantation genetic testing for aneuploidy (PGT-A).

Design: A multicenter retrospective cohort analysis.

Setting: National multicenter fertility practice.

Which obstetrics-gynecology residency programs are training future reproductive endocrinology and infertility fellows? An observational study.

Objective: To identify where reproductive endocrinology and infertility (REI) fellows trained for residency.

Design: Observational, cross-sectional study.

Setting: Not applicable.

Dysregulated expression of GATA2 and GATA6 transcription factors in adenomyosis: implications for impaired endometrial receptivity.

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.

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.

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.

Ovarian Histopathology in Transmasculine Persons on Testosterone: A Multicenter Case Series.

Background: As transmasculine persons utilize androgen gender affirming hormone therapy as a part of transition, guidance has been lacking on the effects of the therapy on the ovaries, especially for those who may desire retention.

Aim: To describe the ovarian histopathology of transmasculine persons on testosterone therapy following oophorectomy at the time of hysterectomy performed for gender affirmation.

Methods: This was a multicenter case series study of transmasculine patients on testosterone therapy who underwent hysterectomy with oophorectomy for gender affirmation between January 2015 and December 2017 at 5 tertiary care referral centers.

Improving the fellowship interview experience for reproductive endocrinology and infertility candidates: a survey.

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.

Uterine pathology in transmasculine persons on testosterone: a retrospective multicenter case series.

Background: As part of transition, transmasculine persons often use testosterone gender-affirming hormone therapy; however, there is limited data on its long-term effects. The impact of exogenous testosterone on uterine pathology remains unclear. While testosterone achieves amenorrhea in the majority of this population, persistence of abnormal uterine bleeding can be difficult to manage.

Forty years of IVF.

This monograph, written by the pioneers of IVF and reproductive medicine, celebrates the history, achievements, and medical advancements made over the last 40 years in this rapidly growing field.

Comparison of patients' reported pain following office hysteroscopy with and without endometrial biopsy: a prospective study.

Background: When performing office based gynecologic procedures, one must provide patients with appropriate counseling on anticipated pain prior to the procedure. The goal of this study was to investigate whether there is any difference in patients' pain perception when office hysteroscopy (OH) is performed alone compared with when it is performed with endometrial biopsy (EMB) for various gynecologic indications.

Methods: A prospective study was performed of patients undergoing office hysteroscopy alone or in combination with endometrial biopsy between October 2015 and February 2017.
