Polycystic ovary syndrome is the primary cause of female infertility. Growing evidence suggests that dysregulation of amino acid metabolism plays a significant role in the onset and progression. However, the underlying mechanism remains unc…

BACKGROUND: Ovarian maldescent is a rare congenital anomaly in which one or both ovaries are positioned abnormally above the pelvic brim. However, the potential relationship between ovarian maldescent and infertility remains poorly understo…

BACKGROUND: The risk of ectopic pregnancy (EP) is known to increase with assisted reproductive technology (ART), but the specific risk factors are unclear. METHODS: We screened 6872 cycles for clinical data that met our study's inclusion c…

BACKGROUND: Overweight and obesity can induce an inflammatory milieu in the oocyte microenvironment and are closely associated with reduced assisted reproductive outcomes. OBJECTIVE: How are immune cells, cytokines and lipid profiles alter…

BACKGROUND: Significant lower genital tract (LGT) dysbiosis and an associated lower rate of clinical pregnancy after in vitro fertilization-frozen embryo transfer (IVF-FET) among polycystic ovary syndrome (PCOS) patients have been previousl…

BACKGROUND: Although numerous studies have investigated the potential correlation between follicular fluid (FF) steroid concentrations and in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes, few have accounted for t…

INTRODUCTION: Conventional intracytoplasmic sperm injection (ICSI) is a widely used treatment for couples with severe male infertility. However, there are controversies regarding the selection and the damage to gametes during the ICSI proce…

OBJECTIVE: To study the effect of aging on ovarian circadian rhythm. DESIGN: Human and animal study. SETTING: University hospital and research laboratory. PATIENTS/ANIMALS: Human granulosa cells were obtained by follicular aspiration fro…

Endometriosis is a benign gynecologic disorder causing dysmenorrhea, pelvic pain, and subfertility. Receptors for the growth hormone-releasing hormone (GHRH) were found in endometriotic tissues. Antagonists of GHRH have been used to inhibit…

BACKGROUND: Adenomyosis (AM) has impaired contraction. This study aimed to explore the expression of potassium channels related to contraction in myometrial smooth muscle cells (MSMCs) of AM. METHODS: Uterine tissue samples from 22 patient…

OBJECTIVE: To investigate the expression of potassium channels and the influence of estrogen and progesterone on the cultured uterine smooth muscle cells (USMC) of adenomyosis in vitro. METHODS: There were 22 cases of adenomyosis hysterect…
