BACKGROUND: This study evaluated the effects of different ovulation trigger strategies on pregnancy outcomes in letrozole-stimulated and modified natural frozen–thawed embryo transfer (L-FET and mNC-FET) cycles. METHODS: A total of 2053 eli…

BACKGROUND: Polycystic ovary syndrome (PCOS) is characterized by chronic low-grade inflammation of the ovaries. This disorder of the immune microenvironment is closely related to abnormal follicular development and ovulation disorders. This…

BACKGROUND: Diminished ovarian reserve (DOR) is associated with impaired female fertility; however, its molecular mechanisms remain incompletely understood. Our previous studies found that individuals with DOR have lower levels of microRNA-…

PURPOSE: To investigate BMAL1 and BMP6 expressive differences in ovarian granulosa cells (OGCs) of patients with polycystic ovary syndrome (PCOS), explore regulatory relationship, assess their impacts on OGC proliferation and apoptosis, and…

OBJECTIVE: This study aimed to analyze the effect of progesterone (P) levels on the human chorionic gonadotropin (hCG) trigger day and the progesterone on hCG day-to-basal progesterone (PhCG/Pbasal) ratio on pregnancy outcomes in patients w…

BACKGROUND: Female reproductive disorders (FRDs) are common diseases among women of childbearing age, affecting their reproductive health. Age at first sexual intercourse (AFS) is potentially linked to FRDs, and this study aims to investiga…

BACKGROUND: Polycystic ovary syndrome (PCOS) is a heterogeneous gynecological endocrine disorder linked to immunity. Cangfu Daotan Decoction (CFDT), a classic Chinese medicine prescription, is particularly effective in treating PCOS, specif…

The aim of this study is to investigate the effect of human chorionic gonadotropin (hCG) in hormone replacement regimen for frozen-thawed embryos. We performed a retrospective cohort study and included patients who underwent frozen embryo t…

BACKGROUND: Previous studies have shown that frozen embryo transfer (FET) resulted in increased live birth rates (LBR) and reduced the risk of ovarian hyperstimulation syndrome (OHSS) than did fresh embryo transfer in women with polycystic …
