Objective: To evaluate the association between endometriosis and the p53 polymorphism.
Design: Prospective study.
Setting: Department of gynecology and genetics in a medical center.
Patient(s): Women with and without endometriosis.
Intervention(s): Women were categorized as having moderate or severe endometriosis (n = 118) or no endometriosis (n = 140).
Main Outcome Measure(s): Polymerase chain reaction was used to detect p53 codon 72 polymorphisms (arginine homozygosity, heterozygosity, and proline homozygosity). Associations between endometriosis and p53 polymorphisms were evaluated.
Result(s): The distributions of different p53 polymorphisms differed significantly between groups. The respective proportions of arginine homozygotes, heterozygotes, and proline homozygotes were 10.2%, 66.9%, and 22.9% in the group with endometriosis and 30.7%, 50%, and 19.3% in the group without endometriosis.
Conclusion(s): Endometriosis is associated with p53 polymorphism. p53 arginine homozygotes have lower risk for endometriosis. Heterozygotes and proline homozygotes have higher risk for endometriosis.

Oxidative stress (OS) is established as a key factor in the etiology of both male and female infertility, arising from an imbalance between reactive oxygen species (ROS) production and the endogenous antioxidant (AOX) defenses. In men, OS adversely affects sperm function by inducing DNA damage, reducing motility, significantly impairing sperm vitality through plasma membrane peroxidation and loss of membrane integrity, and ultimately compromising overall sperm quality. In women, OS is implicated in various reproductive disorders, including polycystic ovary syndrome, endometriosis, and premature ovarian failure, leading to diminished oocyte quality, disrupted folliculogenesis, and poorer reproductive outcomes.

Background: Triglyceride-glucose (TyG) index has been found to be associated with female reproductive disorders, but its relationship with the risk of endometriosis is unknown. Therefore, the aim of this study was to investigate this relationship.
Methods: We performed a two-sample mendelian randomization(MR) analysis to examine the causal effect of TyG index on endometriosis, and inverse variance weighting(IVW) was the main method of analysis.

Introduction: This study aimed to analyze the worldwide, regional burden of endometriosis and its trends from 1990 to 2019, utilizing the latest data from Global Burden of Disease (GBD) 2019. GBD 2019 is a global database tool for comprehensive analysis and an important result of long-term collaboration among governments worldwide.
Methods: We utilized the Global Health Data Exchange Query tool to analyze endometriosis in prevalence numbers, age-standardized prevalence rates (ASPR), and disability-adjusted life-years (DALYs) from 1990 to 2019 in 204 countries and regions.

Research Question: Does metformin reverse endometriosis-associated infertility?
Design: Endometriosis was induced by transplanting uterus fragments from B6CBAF1 mice into recipients of the same strain. The mice were divided into groups: endometriosis (End, n = 24), sham-operated (Sham, n = 12), endometriosis with metformin (0.5mg/ml) orally administered for 3 months (EndMet, n = 21) and sham-operated metformin-treated (ShamMet, n = 16).

We report the case of a woman in her early 30 s who was diagnosed with Robert's uterus. She had been experiencing progressive dysmenorrhea for a decade and sought treatment for infertility at our hospital. Preoperative ultrasound imaging resulted in a misdiagnosis of a complete uterine septum with an accompanying ovarian cyst.
