Endometriosis is a frequent chronic estrogen-dependent condition that can significantly impair fertility and reduce the quality of life in affected individuals. Women with endometriosis face a 30-50% risk of infertility. Multifactorial fact…

OBJECTIVE: To report a case of polypoid ovarian endometrioma mimicking malignant transformation, review the literature on this rare entity, and highlight its implications for surgical management and fertility preservation. DESIGN: Case rep…

Abstract Endometriosis is a chronic disease of gynaecological origin that affects approximately 10% of women worldwide and has a significant impact on patients’ lives. Women with endometriosis attempting to conceive may experience infertili…

INTRODUCTION: Endometriosis is a chronic and estrogen-dependent disorder that affects about 10% of women of reproductive age worldwide. Endometriosis has been associated with chronic inflammation and an atherogenic lipid profile, two condit…

BACKGROUND: Rectal endometriosis is among the most symptomatic forms of the disease. When hormonal therapy fails, surgery is often required. High-intensity focused ultrasound (HIFU) is widely used in gynecology for the treatment of myomas a…

OBJECTIVES: The aim of this study was to investigate the clinical characteristics of women with superficial peritoneal endometriosis (SUP) diagnosed by surgery and not confirmed by histology, compared with histologically proven SUP. DESIGN…

RESEARCH QUESTION: What is the incidence of endometrioma infections requiring surgical drainage following oocyte retrieval in women with ovarian endometrioma? DESIGN: This retrospective observational cohort study included women aged 18-43 …

Endometriosis affects approximately 10% of women of reproductive age and is characterized by the presence of endometrial-like tissue outside the uterine cavity, leading to chronic pelvic pain, infertility, and a significant reduction in qua…

Abstract Study question How does adenomyosis affect live birth rates (LBR) in women undergoing assisted reproductive technology (ART) compared to a matched control population? Summary answer Women with adenomyosis, matched with controls for…

STUDY QUESTION: How does adenomyosis affect live birth rates (LBRs) in women undergoing ART compared to a matched control population? SUMMARY ANSWER: Women with adenomyosis, matched with controls for age, blastocyst count, and top-quality …

BACKGROUND: Endometriosis appears to have a multilayered etiology, with genetic and epigenetic factors each contributing half of the pathogenesis. The molecular processes that underlie the onset of endometriosis are yet unclear, but it is a…

Endometriosis is a chronic gynecologic disease of reproductive-age women, causing menstrual pain and infertility. Endocrine and inflammatory mechanisms drive its development, with estrogen/progesterone imbalance contributing to extrauterine…

Endometriosis often leads to chronic pelvic pain and possible nerve involvement, yet imaging the peripheral nerves remains a challenge. We introduce Visionerves, a novel hybrid AI framework for peripheral nervous system recognition from mul…

Biomarker identification could help in deciphering endometriosis pathophysiology in addition to their use in the development of non invasive diagnostic and prognostic approaches, that are essential to greatly improve patient care. Despite e…

Endometriosis is a complex disease and still many areas of uncertainty exist on the clinical management, from the diagnosis to the treatment. The modern diagnostic workup should include the family history (including genetic and epigenetic f…

OBJECTIVE: To provide evidence regarding the significance of painful symptoms among women suffering from infertility. DESIGN: An observational retrospective cross-sectional study. SETTINGS: University hospital-based research center. PATI…

An anonymous online survey in French was used to assess if endometriosis patients would be as ready as unaffected women to donate their menstrual blood for biological research on endometriosis and evaluate potential barriers to such donatio…

Abstract Study question Do endometriosis women who achieve a live birth (LB) after Hormone Replacement Therapy-Frozen Embryo Transfer (HRT-FET) have different transfer-day progesterone levels than controls? Summary answer In women achieving…

STUDY QUESTION: Do women with endometriosis who achieve a live birth (LB) after HRT-frozen embryo transfer (HRT-FET) have different progesterone levels on the day of transfer compared to unaffected women? SUMMARY ANSWER: In women achieving…
