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…

BACKGROUND: The hormone replacement therapy (HRT) is widely used for endometrial preparation in frozen-thawed embryo transfer (FET), but non-physiological estrogen levels may increase pregnancy complications. This study examined whether red…

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…

STUDY QUESTION: Does the downregulation of cell division cycle 42 (CDC42) protein in endometrial stroma lead to endometrial senescence in patients with recurrent implantation failure (RIF), and what is the potential mechanism? SUMMARY ANSW…

Recurrent implantation failure (RIF) is a rather thorny problem in the clinical practice of assisted reproductive technology. Due to the complex aetiology of RIF, its pathogenesis is far from fully understood, and there is no effective trea…

Embryo adhesion is a very important step in the embryo implantation process. Homeobox A10 (HOXA10), a key transcriptional factor of endometrial receptivity, is indispensable for embryo adhesion. However, how to control the activation status…

BACKGROUND: This study aimed to explore the relationship between serum oestrogen (E2) levels before endometrial transformation and pregnancy outcomes of hormone replacement therapy-frozen embryo transfer (HRT-FET) cycles, which has been inv…

OBJECTIVE: To analyze the clinical outcomes of repeated superovulation induction in patients with adenomyosis or moderate to severe pelvic endometriosis after failure in previous IVF-ET cycles with the ultra-long protocol. METHODS: We retr…
