A systematic review was conducted of the influence of local endometrial injury (LEI) on the outcome of the subsequent IVF cycle. MEDLINE, EMBASE, the Cochrane Library, National Research Register, ISI Conference Proceedings, ISRCTN Register and Meta-register were searched for randomized controlled trials to October 2011. The review included all trials comparing the outcome of IVF treatment in patients who had LEI in the cycle preceding their IVF treatment with controls in which endometrial injury was not performed. The main outcome measures were clinical pregnancy and live birth rates. In total, 901 participants were included in two randomized (n=193) and six non-randomized controlled studies (n=708). The quality of the studies was variable. Meta-analysis showed that clinical pregnancy rate was significantly improved after LEI in both the randomized (relative risk, RR, 2.63, 95% CI 1.39-4.96, P=0.003) and non-randomized studies (RR 1.95, 95% CI 1.61-2.35, P<0.00001). The improvement did not reach statistical significance in the one randomized study which reported the live birth rate (RR 2.29, 95% CI 0.86-6.11). Robust randomized trials comparing a standardized protocol of LEI before IVF treatment with no intervention in a well-defined patient population are needed.

Endometrial injury caused by repeated uterine procedures, infections, inflammation, or uterine artery dysfunction can deplete endometrial stem/progenitor cells and impair regeneration, thereby diminishing endometrial receptivity and evidently lowering the live birth, clinical pregnancy, and embryo implantation rates. Currently, safe and effective clinical treatment methods or gene-targeted therapies are unavailable, especially for severe endometrial injury. Umbilical cord mesenchymal stem cells and their extracellular vesicles are characterized by their simple collection, rapid proliferation, low immunogenicity, and tumorigenicity, along with their involvement in regulating angiogenesis, immune response, cell apoptosis and proliferation, inflammatory response, and fibrosis, Therefore, these cells and vesicles hold broad potential for application in endometrial repair.

Placenta accreta spectrum (PAS) poses a significant risk for maternal morbidity and mortality. There is a global rise in incidence of PAS in tandem with an increase in rates of cesarian section. Previous cesarian section and presence of placenta previa are two independent risk factors for development of PAS.

(1) Background: Volumetric modulated arc therapy (VMAT) can deliver more accurate dose distribution and reduce radiotherapy-induced toxicities for postoperative cervical and endometrial cancer. This study aims to retrospectively analyze the relationship between dosimetric parameters of organs at risk (OARs) and acute toxicities and provide suggestions for the dose constraints. (2) Methods: A total of 164 postoperative cervical and endometrial cancer patients were retrospectively analyzed, and the endpoints were grade ≥ 2 acute urinary toxicity (AUT) and acute lower gastrointestinal toxicity (ALGIT).

Regeneration of the injured endometrium, particularly the functional layer, is crucial for the prevention of uterine infertility. At present, clinical treatment using sodium hyaluronate hydrogel injection is limited by its relatively low fluidity, short-term retention, and insufficient bioactive ingredients, so it is necessary to develop an advanced healing-promoting hydrogel. The modulation of the microenvironment by presents a bioactive component that can facilitate the regeneration of the functional layer.

The endometrium, the inner lining of the uterus, assumes a crucial role in the female reproductive system. Disorders and injuries impacting the endometrium can lead to profound consequences, including infertility and compromised women's overall health. Recent advancements in stem cell research have opened new possibilities for the treatment and repair of endometrial issues.
