BACKGROUND: The differences between adenomyosis subtypes in clinical features and reproductive outcomes remain largely unexplored. This study aimed to compare clinical features and reproductive outcomes after the first frozen embryo transfe…

STUDY QUESTION: Does disrupted cell crosstalk contribute to embryo implantation failure in adenomyosis, and what is the underlying molecular mechanism? SUMMARY ANSWER: Expanded Fibroblast-Specific Protein 1 (FSP1)+ stromal cell populations…

BACKGROUND: Thin endometrium continues to pose a significant challenge in assisted reproductive technology (ART) cycles, necessitating further exploration of therapeutic approaches. Tamoxifen (TMXF) has been primarily used in ovarian stimul…

Defective endometrial decidualization is one major cause of female infertility, yet the underlying mechanisms remain elusive. Here, we identified that protein arginine methyltransferase 5 (PRMT5), which was upregulated during decidualizatio…

BACKGROUND: To assess sequential embryo transfer's impact on clinical outcomes in frozen embryo transfer (FET) cycles for patients with multiple transfer failures. METHODS: This retrospective cohort study encompasses 4,499 FET cycles invol…

OBJECTIVE: To identify the key factors associated with biochemical pregnancy loss (BPL) following single blastocyst transfer in frozen embryo transfer (FET) cycles utilizing hormone replacement therapy (HRT). METHODS: This retrospective co…

Existing evidence shows the importance of circulating cytokines in studying female reproductive system dysfunction. Endometriosis (EM) is thought to be associated with multiple immune cytokines, but its causality has not been proven. Utilis…

PURPOSE: To compare pregnancy outcomes of four endometrial preparation methods prior to frozen embryo transfer (FET). METHODS: A total of 3,030 programmed cycles were analyzed: 302 with natural cycle (NC), 131 with ovulation induction (OI)…

IN BRIEF: Preeclampsia is a severe pregnancy-related complication that can result in adverse maternal and fetal outcomes. Current therapeutic options for preeclampsia remain limited. This study demonstrates that epicatechin can inhibit pyro…

BACKGROUND: Several studies have demonstrated that pre-treatment with long-acting Gonadotropin-Releasing Hormone agonists (GnRHa) can significantly enhance the clinical pregnancy rate among recurrent implantation failure (RIF) patients. Inv…

Mesenchymal stem/stromal cells (MSCs) possess significant potential in regenerative medicine, attributed to their inherent capacity for site-specific homing to inflammatory regions, diverse differentiation abilities, and immunomodulatory fu…

BACKGROUND: While endometriosis (EM) has been previously associated with multiple immune factors, the causal relationship underlying these associations remains unclear. OBJECTIVE: In this study, Two-sample Mendelian randomization (MR) meth…

STUDY QUESTION: Does abnormal serotonin homeostasis contribute to impaired endometrial decidualization in patients with recurrent implantation failure (RIF)? SUMMARY ANSWER: Abnormal serotonin homeostasis in patients with RIF, which is acc…

BACKGROUND: The objective of this research was to elucidate the association between the length of infertility and the outcomes of intrauterine insemination (IUI) in women of varying ages - a topic that has been the subject of investigation …

BACKGROUND: Endometriosis, a common gynecological condition, can cause symptoms such as dysmenorrhea, infertility, and abnormal bleeding, which can negatively affect a woman's quality of life. In the current study, the pathophysiological me…

BACKGROUND: Previous studies suggested higher serum progesterone (P) levels were strongly associated with a lower clinical pregnancy rate (CPR) for in vitro fertilization-embryo transfer (IVF-ET). However, the effect of increased serum P le…

RESEARCH QUESTION: To investigate the effects of two protocols (hormone replacement therapy (HRT) alone or in combination with tamoxifen) on the endometrium and pregnancy outcome of patients with thin endometrium in frozen-thawed embryo tra…

OBJECTIVE: This study assessed the impacts of in vitro culture times of cleavage embryos on clinical pregnancy outcomes. METHODS: This retrospective cohort study was performed at the Reproductive Medicine Department of Hainan Modern Women …

RESEARCH QUESTION: Hormone replacement therapy (HRT) is one of the most used endometrial preparation protocols for frozen embryo transfer (FET) due to the convenience of its administration and stability of pregnancy outcomes. There are seve…

Endometrial receptivity damage caused by impaired decidualization may be one of the mechanisms of infertility in endometriosis (EMs). Our previous study demonstrated that Calpain-7 (CAPN7) is abnormally overexpressed in EMs. Whether CAPN7 a…

BACKGROUND: Poor decidualization and abnormal autophagy conditions in the endometria of adenomyosis patients have been reported previously. However, the specific regulatory mechanism of decidualization in adenomyosis and its relationship wi…

BACKGROUND: Timely and moderate luteinizing hormone (LH) supplementation plays positive roles in in vitro fertilization/intracytoplasmic sperm injection and embryo transfer (IVF/ICSI-ET) cycles with long-acting gonadotropin-releasing hormon…

Decidualization is a prerequisite for successful embryo implantation, in which elongated fibroblast-like endometrial stromal cells differentiate into more rounded decidual cells. Accumulating evidence has stressed the important role of the …
