A Prospective Cohort Study of Metformin as an Adjuvant Therapy for Infertile Women With Endometrial Complex Hyperplasia/Complex Atypical Hyperplasia and Their Subsequent Assisted Reproductive Technology Outcomes.

Objective: To investigate the adjuvant efficacy of metformin treatment to achieve pathological complete response (CR) in patients with endometrial complex hyperplasia (CH) and complex atypical hyperplasia (CAH), and secondarily, to evaluate their pregnancy outcomes after following assisted reproductive technology (ART).

Study Design: This prospective cohort study analyzed 219 patients diagnosed with infertility and CH/CAH from January 2016 to December 2020. Among these patients, 138 were assigned to the control group (progesterone alone) and 81 were assigned to the study group (progesterone+metformin).

Effects of bicornuate uterus on pregnancy and obstetric outcomes of in vitro fertilization / intracytoplasmic sperm injection.

Objective: A bicornuate uterus results from failure of the Müllerian ducts to completely fuse. If patients with bicornuate uterus are diagnosed with infertility, they can conceive with help from in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). With few studies on the reproductive performances of bicornuate uterus following IVF/ICSI treatment, the aim of present study is to investigate whether a bicornuate uterus would affect pregnancy rates and obstetric outcomes of infertile women.

Does a hyperechogenic endometrial mass in the uterus during controlled ovarian stimulation affect assisted reproductive technology cycle outcomes?

Objectives: Healthy embryos and endometrial receptivity are keys to the success of in-vitro fertilization and embryo transfer (IVF-ET). Abnormal transvaginal ultrasonography (TVU) findings in the endometrium are a concern during assisted reproductive technology (ART) treatments. Observation of a hyperechogenic endometrial mass (HEM) during controlled ovarian stimulation (COS) in an IVF or intracytoplasmic sperm injection (ICSI) cycle is a dilemma.

A New Hysteroscopic Scoring System for Diagnosing Chronic Endometritis.

Study Objective: To develop a new hysteroscopic morphologic scoring system to diagnose chronic endometritis (CE).

Design: Prospective study.

Setting: Medical hysteroscopy office.

Optimal waiting period for fresh embryo transfer after hysteroscopic adhesiolysis: a retrospective cohort study.

Background: Very few studies have been conducted regarding the optimal time interval between hysteroscopic adhesiolysis and the embryo transfer (ET). Investigation of this optimal time may be helpful for assisted reproductive technology. Therefore, we investigated effects of the interval between hysteroscopic adhesiolysis and ET upon in vitro fertilization (IVF) cycle outcomes.
