Purpose: To determine if endometrial injury prior to the first or second in vitro fertilization (IVF) cycle affects clinical pregnancy rates.
Methods: This study was a randomized, multicentre, controlled study performed at three Canadian outpatient fertility clinics. Patients undergoing their first or second IVF cycle were randomized to a single endometrial injury 5-10 days prior to the start of gonadotropins in an IVF cycle compared to no injury. The primary outcome was clinical pregnancy rate. Secondary outcomes were live birth rates, implantation rate, endometrial thickness, number of oocytes retrieved and the rate of embryo cryopreservation.
Results: Fifty-one women were randomized (25 in the en dometrial injury group and 26 in the control group); however, the study was terminated prematurely due to slow recruitment (target 332 patients). Groups were similar at baseline for: age, duration of infertility, BMI, day 3 FSH, and the number having first IVF cycle. The groups were similar for gonadotropin dose, endometrial thickness, number of oocytes retrieved, and embryo cryopreservation rate. The clinical pregnancy rate in the endometrial injury group was 52% (13/25) and 46% (12/26) in the control group (p = 0.45). Live birth rate in the endometrial injury group was 52% (13/25) and 35% (9/26) in the control group (p = 0.17). The implantation rate was also similar (58% vs. 45%, p = 0.17).
Conclusions: This study did not detect a difference in implantation, clinical pregnancy or live birth rates; however, the lack of difference in this study may be because it was underpowered. CLINICAL TRIALS REGISTRATIONS: gov: NCT01983423.

: This study aims to evaluate and compare the safety and efficacy of the da Vinci Xi and hinotori™ SRS robot-assisted surgical systems for gynecologic disorders. : We conducted a retrospective study of 401 cases (43 benign uterine tumors; 88 pelvic organ prolapses; 270 low-risk endometrial cancers) of robot-assisted surgery performed at Kagoshima University Hospital between January 2017 and October 2024. Surgical factors such as the operative time, blood loss, and complication rates were analyzed and compared between the da Vinci Xi (332 cases) and hinotori™ SRS (69 cases) systems.

Background: Uterine cystic adenomyosis is a rare form of focal adenomyosis that is primarily located within the myometrium. In this case report, we present a unique case of adult uterine cystic adenomyosis found outside the uterus following laparoscopic myomectomy.
Case Presentation: The patient was a 36-year-old Chinese woman who had previously undergone laparoscopic surgery at our hospital to remove a 4 cm diameter diameter uterine fibroid six years prior.
The Application of Hydrogels in the Treatment of Intrauterine Adhesions.
Curr Pharm Des

Metabolic Syndrome Research Center, Mashhad University of Medical Sciences, Mashhad, Iran.
Intrauterine Adhesions (IUA) are a significant cause of infertility and miscarriage, often resulting from trauma to the endometrium. While hysteroscopic adhesiolysis is the primary treatment, the use of hydrogels as anti-adhesion barriers and drug delivery systems is gaining traction for improving patient outcomes. This review aims to explore various hydrogel types, their role in tissue repair, and the integration of stem cell therapy.

Nowadays, extracellular vesicles (EVs) such as exosomes participate in cell-cell communication and gain attention as a new approach for cell-free therapies. Recently, various studies have demonstrated the therapeutic ability of exosomes, while the biological effect of human endometrial stem cell (hEnSC)-derived small EVs such as exosomes is still unclear. Herein, we obtained small EVs from hEnSC and indicated that these small EVs activate the vital cell signaling pathway and progress neurite outgrowth in PC-12 cell lines.

Introduction: This study evaluated the safety and tolerability of fezolinetant in women with vasomotor symptoms (VMS) due to menopause in a pooled analysis of data from three 52-week phase 3 studies (SKYLIGHT 1, 2, and 4).
Methods: SKYLIGHT 1 and 2 were double-blind, placebo-controlled studies where women (≥ 40 to ≤ 65 years), with moderate to severe VMS (minimum average ≥ 7 hot flashes/day) were randomized to once-daily placebo, fezolinetant 30 mg or 45 mg. After 12 weeks, those on placebo were re-randomized to fezolinetant 30 mg or 45 mg, while those on fezolinetant continued on their assigned dose for 40 weeks.
