Aim: The aim of this study is to assess the effects of hydrosalpinx on ultrasonographic parameters for endometrial receptivity during the window of implantation, as measured by power color Doppler ultrasound.
Methods: The women recruited to this study included sixty with unilateral or bilateral hydrosalpinx and fifty-seven prior to in vitro fertilization-embryo transfer (IVF-ET) or artificial insemination (AI) performed due to male infertility. Ultrasonographic parameters for endometrial receptivity were measured during the window of implantation by power color Doppler ultrasound.
Results: The proportion of triple-line endometrial pattern and uterine contractions from the cervix to the fundus were significantly lower in the hydrosalpinx group than in the control group. In addition, patients in the hydrosalpinx group had a significantly lower pulsatility index (PI) of uterine spiral arteries. There were no significant differences in endometrial thickness, subendometrial blood flow distribution pattern, uterine artery PI, uterine artery resistance index (RI), or uterine spiral artery RI between the two groups.
Conclusions: Hydrosalpinx may be involved in the regulation of endometrial receptivity through its influence on endometrial pattern, uterine contractions, and PI of the uterine spiral arteries.

Background: One potential cause of implantation failure is abnormal endometrial receptivity, and how to objectively evaluate endometrial receptivity has been a matter of great concern. Endometrial receptivity analysis (ERA), a next-generation sequencing-based test that assesses endometrial gene expression, may be valuable in predicting endometrial receptivity, but whether ERA improves pregnancy outcomes in patients with recurrent implantation failure (RIF) is currently controversial. The purpose of this study was to investigate the effect of ERA on pregnancy outcomes in patients with RIF.

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.

The endometrial and vaginal microbiota have co-evolved with the reproductive tract and play a key role in both health and disease. However, the difference between endometrial and vaginal microbiota, as well as their association with reproductive outcomes in women undergoing frozen embryo transfer, remains unclear. 120 women who underwent in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) and whole embryo freezing were enrolled.

Hypothyroidism causes ovarian dysfunction and infertility in women and animals and impairs the hypothalamic expression of kisspeptin (Kp). However, kisspeptin is also expressed in the genital system, and the lack of the Kp receptor (Kiss1r) in the uterus is linked to reduced implantation rates. This study investigated the impact of hypothyroidism on the uterine expression of Kp and Kiss1r in female rats throughout the estrous cycle and the associated changes in uterine activity modulators.

: Autologous platelet-rich plasma (PRP) transfusions are a relatively new treatment method used in different fields of medicine, including the field of reproductive medicine. One of the applications of these concentrated platelet infusions is the treatment of endometrial receptivity, which is a key factor for embryo implantation. There are implications that PRP infusions can lead to increased endometrial thickness, endometrial receptivity, and significantly elevated clinical pregnancy rates.
