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…

OBJECTIVE: To present two cases of primary ovarian squamous-cell carcinoma (POSCC) and describe a comprehensive review and analysis of the published related literature. METHODS: We reviewed the medical records of two patients with POSCC wh…

OBJECTIVES: This study analyzed clinical pregnancy outcomes in patients undergoing in vitro fertilization-embryo transfer with donor sperm (IVF-D) using different ovulation induction protocols, to provide reference data for selecting approp…

Endometriosis (EMs) is characterized by the establishment and persistence of ectopic lesions, a process fundamentally dependent on aberrant angiogenesis. Endothelial cells (ECs) play a central role in this process; however, accumulating evi…

OBJECTIVE: To investigate whether the clinical predictors of achieving a clinical pregnancy differ between fresh and frozen embryo transfer cycles in patients with recurrent implantation failure (RIF) undergoing their first ART treatment af…

BACKGROUND: In vitro maturation (IVM) presents a potential alternative to conventional IVF for special subgroups of infertile couples. Anti-Müllerian Hormone (AMH) is widely regarded as the most robust biomarker for assessing ovarian reserv…

Organoids are three-dimensional multicellular structures derived from stem cells or primary tissues that recapitulate key structural and functional features of native organs. Advances in stem cell biology, biomaterials, and bioengineering h…

Endometriosis (EMs) is an estrogen-dependent, chronic inflammatory disorder characterized by immune microenvironment dysregulation, a critical factor in its pathogenesis. Despite existing therapies, limitations persist, highlighting the urg…

OBJECTIVE: The aim of the present study was to analyze pregnancy outcomes among patients diagnosed with first-trimester decidual polyps (DPs) following fresh embryo transfer who underwent expectant management and to further explore risk fac…

BACKGROUND: In clinical practice, repeated oocyte retrieval cycles are often necessary for patients with diminished ovarian reserve (DOR). It has been hypothesized that the mechanical stimulation from the initial oocyte pick-up (OPU) proced…

Microplastics (MPs) are widespread environmental contaminants detected in multiple human tissues, raising significant health concerns. The detection of MPs from human reproductive tissues largely indicates potential risks to reproductive he…

BACKGROUND: Environmental exposure to trace and heavy metals may influence female fertility, yet their impact on assisted reproductive outcomes remains poorly defined. Maternal diet can potentially modulate metal-related toxicity by influen…

The human endometrium undergoes dynamic changes across the menstrual cycle to establish a receptive state for embryo implantation. Using bulk and single-cell RNA-Seq, we characterized gene expression dynamics in the cycling endometrium and …

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: Chronic hepatitis B (HBV) and hepatitis C (HCV) infections represent a substantial global health burden and increasing numbers of infertile women with chronic HBV/HCV infections seek conception through in vitro fertilization (IV…

Polycystic ovary syndrome (PCOS) is one of the most common reproductive disorders in women and severely impairs fertility. Extant clinical studies can only provide indirect and plausible evidence to support endometrial dysfunction as an ova…

INTRODUCTION: Chronic endometritis (CE) is regarded as a potential factor contributing to infertility and embryo implantation failure. The cause of CE remains unclear at present, but it might be associated with intrauterine microbial infect…

Anti-synthetase syndrome (ASS) is a rare autoimmune condition characterized by the presence of anti-aminoacyl tRNA synthetase (ARS) antibodies and systemic features such as interstitial lung disease and myositis. Although autoimmune disorde…

OBJECTIVES: Tuberculosis (TB) is a common cause of infertility in humans, especially in regions with high TB prevalence. However, the impact of latent TB infection (LTBI) on pregnancy outcomes following assisted reproduction in patients wit…

BACKGROUND: While anti-Müllerian hormone (AMH) serves as a well-established biomarker of ovarian reserve, its association with early miscarriage risk remains inconsistently characterized across previous research. To address this evidence ga…

BACKGROUND: Natural cycle in vitro fertilization (NC-IVF) represents a convenient and safe assisted reproductive technology, making it particularly advantageous for patients with poor ovarian response (POR). This research evaluates the effe…

BACKGROUND: Oocyte vitrification, a widely utilized assisted reproductive technology for fertility preservation, can address emergencies arising from the unavailability of sperm from the male partner on the day of oocyte retrieval. However,…

Ectopic pregnancy (EP) is a common yet fatal complication of in vitro fertilization-embryo transfer (IVF-ET) and intracytoplasmic sperm injection (ICSI). We aim to establish and validate a nomogram in patients undergoing double fresh cleava…

PURPOSE: Maternal age-related fertility decline is considered to be directly attributed to either embryonic or endometrial factors. Aneuploidy, as the dominant defect in aging embryos, has long diverted attention away from the effects of en…

Whether and how endometrial aging affects fertility remains unclear. In our in-house clinical cohort at the Center for Reproductive Medicine of Peking University Third Hospital (n = 1,149), we observed adverse pregnancy outcomes in the midd…
