BACKGROUND: Trends toward earlier age at menarche, the starting point in women’s reproductive lifespan, have been observed globally. Whether an earlier age at menarche influences Anti-Müllerian hormone (AMH), a clinical indicator of ovarian…

Per- and polyfluoroalkyl substances (PFAS) have been previously associated with polycystic ovary syndrome (PCOS). However, the health effects of emerging PFAS alternatives on PCOS remain unclear. This study aims to examine the associations …

BACKGROUND: Embryo implantation failure and early pregnancy loss remain significant challenges in assisted reproductive technology (ART). Lipid peroxidation is known to be involved in reproductive physiology. However, its role during the im…

OBJECTIVE: The study systematically examines the long-term trends in the global burden of Polycystic ovary syndrome (PCOS) across 204 countries and territories, with a specific focus on comparing pre-pandemic (1990-2019) and post-pandemic (…

With women aged ≥50 years projected to reach 1.65 billion by 2050, gynecological and breast cancers impose an escalating postmenopausal burden. Whether menopausal timing independently influences cancer risk remains uncertain. We integrated …

BACKGROUND: Optimal endometrial thickness and receptivity, precisely regulated by steroid hormones, are critical determinants for successful embryo implantation. Thin endometrium is a major cause of female infertility, yet its pathogenesis …

The emergence of organoids has received widespread attention for faithful recapitulation of physiological and pathological conditions, together with overcoming the major bottleneck of extrapolating laboratory findings from model systems to …

Adenomyosis (AM) commonly affects women of reproductive age and can impair female fertility, yet its diagnosis and pathogenesis remain challenging. We compared serum IgG1 Fc‑glycosylation profiles between AM patients (n = 30) and non‑AM con…

OBJECTIVE: The aim of this study is to explore the relationship between the levels of anti-Müllerian hormone (AMH) and metabolic and reproductive outcomes across different polycystic ovary syndrome (PCOS) phenotypes. METHODS: In this retro…

OBJECTIVE: Women with premenstrual disorder (PMD) display heightened sensitivity to hormonal changes and may be at risk for psychiatric disorders during other hormonally dynamic periods such as pregnancy and postpartum. While PMD has been l…

BACKGROUND AND PURPOSE: Endometriosis is a chronic, hormone-dependent disorder characterized by ectopic implantation of endometrial tissue, often accompanied by pain and infertility. Although the progesterone receptor modulator RU486 is eff…

BACKGROUND & OBJECTIVE: To assess the association of assisted reproductive technologies (ART) conception with postpartum hemorrhage (PPH) during the peripartum and postpartum periods. METHODS: Clinical records of 11,497 patients enrolled i…

The diverse and dynamic population of microorganisms present in the gut microbiota may affect host health. There are evidences to support the role of gut microbiota as a key player in reproductive development. Unfortunately, the relationshi…

OBJECTIVE: To investigate the correlation between preoperative pathologic characteristics and the risk of postoperative recurrence in endometriosis (EMs) patients, and to develop a clinical predictive model. METHODS: A retrospective analys…

INTRODUCTION: A transient window of uterine receptivity ensures that embryos implant in an optimal endometrial environment. Failure to establish or premature closure of the implantation window is thought to be a major cause of infertility, …

PURPOSE: Endometriosis has been hypothesized to increase the risk of preeclampsia (PE) and eclampsia, although the exact mechanism of this relationship is not clear. This study aimed to further explore the potential association between endo…

OBJECTIVES: Previous studies suggested that immune factors may play critical roles in female infertility, but their causal links remain unclear. To address this gap, this study employs the Mendelian randomization (MR) to delineate the causa…

BACKGROUND: Heart failure (HF) represents the terminal stage of various cardiovascular disorders, with immunogenic cell death (ICD) potentially influencing HF progression through modulation of immune cell activity. This study aimed to ident…

Primordial follicles form the non-renewable germline reserve in female mammals; their limited number is a key determinant of reproductive lifespan and is crucial for female fertility. Insufficient or parasomnia sleep is common in females, y…

BACKGROUND: Preimplantation genetic testing for chromosomal structural rearrangements (PGT-SR) has been widely utilized to select euploid embryos in patients carrying balanced chromosomal rearrangements (BCRs) by chromosome copy number anal…

Minimally invasive gynecologic surgery (MIGS) has changed gynecologic care over the past thirty years by introducing techniques like multiport laparoscopy, robotic-assisted laparoscopy, and single-site surgery. MIGS offers advantages like r…

Biofilms are ubiquitous surface-associated bacterial communities embedded in an extracellular matrix. It is commonly assumed that biofilm cells are glued together by the matrix; however, how the specific biochemistry of matrix components af…

Endometriosis (EM) is a common gynecologic condition that often leads to infertility in women of reproductive age. Cell adhesion molecule 2 (CADM2) is involved in maintaining cell adhesion and polarity, as well as suppressing tumors. Howeve…
