ObjectiveTo investigate the association between the dynamic trajectories of urinary human chorionic gonadotropin (hCG) and the risk of early miscarriage after embryo transfer.MethodsIn this prospective cohort study conducted in Hebei Matern…

BACKGROUNDS: Abnormal cleavage (ABNCL) in early human embryos is a frequent phenomenon associated with impaired developmental competence and reduced reproductive potential. However, the clinical determinants of ABNCL and its subtypes remain…

This study aimed to investigate how levels of serum follicle-stimulating hormone (FSH) on Day 7 of ovarian stimulation are related to the number of oocytes retrieved, and identify any cutoff or threshold point in protocols using gonadotropi…

Endometriosis is a benign yet invasive disease characterized by ectopic endometrial growth and immune remodeling. While emerging evidence implicates cellular senescence in disease progression, the underlying mechanisms remain largely undefi…

RATIONALE: Endometrial vascular dystrophy is a rare and poorly understood pathological condition characterized by tortuous and dilated blood vessels visible under hysteroscopy. Diagnosing this condition is challenging due to its potential r…

In the field of genetic breeding, primordial germ cells (PGCs) have become essential cells for gene editing and genetic improvement due to their unique developmental potential and genetic characteristics. However, the low proliferation effi…

BackgroundSpontaneous ureteral rupture is a rare and emergent urological entity, with limited literature guiding its diagnosis and management. Its non-specific presentation can lead to delayed recognition, posing risks of severe complicatio…

PurposeZygotes with 2.1 pronuclei (2.1PN) present with two normal-sized pronuclei, and an additional smaller pronucleus, that is approximately smaller than two thirds the size of a normal pronucleus. It remains unclear whether the additiona…

BackgroundPre-clinical studies showed the anti-tumor mechanisms of PARP inhibitors (PARPi) and platinum have some crossover and overlap in the DNA damage repair pathway, patients who respond to platinum-based chemotherapy are also more like…

ObjectiveTo investigate the vaginal and gut microbes changes during the carcinogenesis of cervical and the auxiliary diagnostic value. To investigate the effect of microbiome-specific metabolites butyric on cervical cancer cells.MethodsWe s…

INTRODUCTION: Preoperative ureteral catheterization/stenting (stenting) and intraoperative diagnostic cystoscopy (cystoscopy) may help prevent or identify intraoperative ureteral injuries (IUIs) during abdominopelvic surgery. In order to pr…

PurposeWe aimed to compare the DNA methylation profiles of human embryos cultured in uninterrupted or interrupted incubators.MethodsThis study included 9 women, ≤ 30 years old (range: 20-30 years), without a history of genetic diseases or s…

The lymphatic system is a channel for fluid transport and cell migration, but it has always been controversial in promoting and suppressing cancer. VEGFC/VEGFR3 signaling has long been recognized as a major molecular driver of lymphangiogen…

BackgroundTuberculosis (TB), a multisystemic disease with protean presentation, remains a major global health problem. Although concurrent pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB) cases are commonly observed clini…

ObjectiveTo explore the correlation of lipid accumulation product (LAP) with metabolic syndrome (MS) and to assess the predictive value of LAP for MS risk in polycystic ovary syndrome (PCOS) with different body mass index (BMI).MethodsA tot…

This study was to evaluate whether Intracytoplasmic sperm injection (ICSI) can improve the quality of embryo in patients with poor-quality embryos in the previous In-vitro fertilization (IVF) cycle, which was cancelled before transfer. This…

BACKGROUND: Endometriosis is a common nonfatal gynecological disease, and infertility is one of its main dangers. Endometriosis-related infertility causes serious damage to women's health and places a burden on women of reproductive age. Th…

BackgroundInfertility is estimated to occur in 1 out of every 4-7 couples. Intracytoplasmic sperm injection (ICSI), a type of assisted reproduction introduced in 1992, has been used across the world for almost all indications of infertility…

PurposeWe aimed to evaluate the link between the GDF9 concentration in day 3 human embryo culture medium and embryo quality and viability.MethodsTwo independent, prospective, observational studies were conducted. In study 1, a total of 280 …

To evaluate the relationship between the initial follicle stimulating hormone (FSH) dose and the number of available cleavage-stage embryos in in vitro fertilization (IVF) cycles.We included 8772 fresh IVF cycles using a GnRH antagonist pro…

Leuprorelin is a synthetic analogue of naturally occurring gonadotropin-releasing hormone. It is currently approved in the United States, Europe and Asia and has indications in advanced prostate cancer, endometriosis, breast cancer and prec…

BACKGROUND/AIMS: Mitochondrial homeostasis is implicated in the development and progression of endometriosis through poorly defined mechanisms. Mst1 is the major growth suppressor related to cancer migration, apoptosis and proliferation. Ho…

The etiology and pathophysiology of endometriosis remain unclear. The aim of the current study was to identify a candidate pathogenic gene, as well as potential biomarkers of endometriosis using messenger RNA (mRNA) sequencing (mRNA-seq). T…

The PvuII (C > T), XbaI (A > G) and (TA)n polymorphisms of ESR1 gene are potentially associated with susceptibility to endometriosis. A meta-analysis was conducted to evaluate comprehensively the associations between endometriosis and ESR1 …

Endometriosis is a common gynecological disease with high prevalence, while its etiology and pathophysiology have remained to be fully elucidated. Previous evidence suggested that this disorder may be in part or completely of somatic origin…
