Although per- and polyfluoroalkyl substances (PFAS) exposure has been linked to endometriosis, this association remains controversial, and the underlying mechanisms are unclear. This study aimed to investigate this relationship and explore …

PURPOSE: To investigate and compare the clinical characteristics and risk factors between intrinsic and extrinsic adenomyosis (AM), as well as the differences in their perioperative management and findings in the two subtypes. METHODS: Thi…

RNF144 family proteins, including RNF144A and RNF144B, members of the RING-between-RING domain-containing ubiquitin E3 ligase family, serve as critical regulators of protein ubiquitination. Despite increasing research attention in recent ye…

Polycystic ovary syndrome (PCOS) is a multifactorial endocrine disorder characterized by chronic anovulation, hyperandrogenism, and polycystic ovarian morphology, leading to infertility. Elevated basal luteinizing hormone (bLH) levels in PC…

The present study aimed to explore whether there is an association between the transfer of frozen thawed embryos (FET) obtained during SARS-CoV-2 infection and an increased risk of adverse pregnancy outcomes. We performed a case-control coh…

This study investigated the prognostic impact of lymph node dissection (LND) in patients with stage I ovarian endometrioid carcinoma (OEC) and aimed to identify the optimal LND range for improved survival. By analyzing data from the Surveil…

BACKGROUND: Ovarian aging is the main cause of reduced reproductive life span, yet its metabolic profiles remain poorly understood. This study aimed to reveal the metabolic homogeneity and heterogeneity between physiological and pathologica…

BACKGROUND: Endometriosis involves the intestine, and its clinical manifestations are nonspecific and lack of etiological manifestations. The diagnosis is difficult, which often leads to misdiagnosis. We report a case of endometriosis which…

Myocardial infarction (MI) results in cardiomyocyte necrosis and conductive system damage, leading to sudden cardiac death and heart failure. Studies have shown that conductive biomaterials can restore cardiac conduction, but cannot facilit…

OBJECTIVE: Additive human menopausal gonadotropin (HMG)/recombinant luteinizing hormone (r-LH) to follicle-stimulating hormone (FSH) can improve pregnancy outcomes in patients with poor ovarian response during assisted reproductive procedur…

The safety and clinical effectiveness of preimplantation genetic testing for aneuploidy (PGT-A) in improving pregnancy outcomes for sub-fertile patients remains controversial. Potential sex-based differences in the relationship between PGT-…

Early pregnancy loss (EPL) is a common event in human reproduction and is classified into histological subtypes such as hydropic abortion (HA) and hydatidiform moles, including complete hydatidiform moles (CHMs) and partial hydatidiform mol…

BACKGROUND: Letrozole has been proven to be an effective method for inducing ovulation. However, little attention has been paid to whether the lead follicle size will affect the success rate of intrauterine insemination (IUI) with ovulation…

BACKGROUND: Surgery for adnexal mass does occur in pregnant women and therefore the choice of surgery during pregnancy needs to be carefully considered and studied. This study aimed to evaluate the safety and feasibility of Laparo-endoscopi…

Introduction: Endometriosis (EMS) is characterized as a prevalent gynecological inflammatory disorder marked by the existence of endometrial tissues situated beyond the uterus. This condition leads to persistent pelvic pain and may contribu…

BACKGROUND: The efficiency of different first-line treatments, such as first-line surgery and assisted reproductive technology (ART), in women with deep infiltrating endometriosis (DIE) is still unclear due to a lack of direct comparative t…

BACKGROUND: Semaphorin 3A (Sema3A) is a member of neural guidance factor family well-known for inducing the collapse of nerve cell growth cone and regulating nerve redistribution. It also has been characterized as an immunoregulatory and tu…

Accumulating oxidative damage is a primary driver of ovarian reserve decline along with aging. However, the mechanism behind the imbalance in reactive oxygen species (ROS) is not yet fully understood. Here we investigated changes in iron me…

INTRODUCTION: Endometriosis (EM) is an estrogen-dependent benign gynecologic disease affecting approximately 10% of reproductive-age women with a high recurrence rate, but lacks reliable biomarkers. No previous studies have investigated the…

BACKGROUND: Accurate preoperative diagnosis of endometrial cancer (EC) with deep myometrial invasion (DMI) is critical to deciding whether to perform lymphadenectomy. However, the presence of adenomyosis makes distinguishing DMI from superf…

PURPOSE: We aimed to develop and validate a predictive score to estimate the post-operative recurrence risk after laparoscopic excision of ovarian endometrioma (OMA). PATIENTS AND METHODS: The prediction score was developed using a trainin…

BACKGROUND: Drug repositioning (DR) refers to a method used to find new targets for existing drugs. This method can effectively reduce the development cost of drugs, save time on drug development, and reduce the risks of drug design. The tr…

ObjectiveTo explore the experiences of patients with ectopic pregnancies with delayed medical care, with the goals to promote timely access to care, reduce subsequent physical and psychological impacts, and provide recommendations for impro…
