Endometriosis (EMS) is a highly heterogeneous chronic gynecological disease characterized by pain, infertility, and relapse, with its etiology and pathogenesis not yet fully elucidated. Traditional theories, including "retrograde menstruation," "implantation …
Neonatal uterine bleeding (NUB) has been hypothesized as a relatively common early-life event potentially linked to the later development of endometriosis through retrograde menstruation. However, its true prevalence and biological …
Several hypotheses have been proposed to explain the establishment of endometriosis, of which retrograde menstruation remains the most widely accepted mechanism of dissemination. However, the mechanisms governing selective lesion establishment …
Current models of endometriosis (EMs) still have limitations in replicating the key pathological features of human EMs, particularly the cyclic bleeding associated with ectopic lesions. To address this gap, this …
Obstructed hemivagina and ipsilateral renal anomaly syndrome was first identified by Purslow in 1922 as a result of abnormal embryologic development of the Müllerian (paramesonephric) and Wolffian (mesonephric) ducts. The …
This study investigated how chronic pelvic pain (CPP) develops using rhesus macaques with naturally occurring endometriosis and a multiple-lesion induction mouse model (MIM), as repeated retrograde menstruation is considered an …
The origin of ectopic gynecologic lesions has been debated since 1927, when Sampson first proposed retrograde menstruation as the underlying cause of endometriosis. Reproduction in mammals is an unusually permissive …
Endometriosis is a chronic, estrogen-dependent inflammatory disorder affecting ~10% of reproductive-age women. It is underdiagnosed, with delays of 5-12 years. Symptoms include dysmenorrhea, chronic pelvic pain, dyspareunia, dyschezia, dysuria, fatigue, …
Can transvaginal ultrasonography (TVUS) reliably detect and quantify free pelvic fluid (FPF) as a surrogate marker of retrograde menstruation, and how do its volume and characteristics vary across menstrual phases, …
Objectives: The peritoneal cavity is a cavity outside the bloodstream, with a specific hormonal, immunological and microbiological micro-environment distinct from plasma. The mesothelial cells lining the peritoneal cavity react within …
