Challenging the paradigm that neonatal uterine bleeding represents the first menstrual episode.

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 …

Peritoneal Hypoxia as a Gatekeeper Between Physiologic Retrograde Menstruation and Pathologic Persistence in Endometriosis.

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 …

A novel mouse model of endometriosis: Simulating the recurrent hemorrhagic microenvironment of clinical lesions.

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 …

Repeatedly occurring retrograde menstruation intensifies central sensitization driven by neuroinflammation in endometriosis models.

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 uterine secretome initiates growth of gynecologic tissues in ectopic locations: re-evaluating the evidence.

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 …

[Endometriose i klinisk praksis].

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, …

Increased C-Reactive Protein Concentrations During Menstruation May Be Important for the Pathophysiology of Endometriosis and Possibly for Adhesion Formation-A Systematic Review.

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 …

Redefining the contribution of retrograde menstruation to endometriosis: single-cell analysis of endometriotic lesions suggests a process more complex than simple autografting.

The Paradox of Endometriosis in Mayer-Rokitansky-Kuster-Hauser Syndrome: Applying Three Criteria to Discriminate Between Retrograde Menstruation/Implantation and Coelomic Metaplasia/Embryonic Cell Rests Theories.

Background/Objectives: The scientific community is still divided between supporters of the implantation theory and researchers who advocate the theory of coelomic metaplasia/embryonic cell remnants to explain the initiation of endometriosis. …

The role of Fusobacterium nucleatum in the pathogenesis of endometriosis: A microbial and microenvironmental perspective.

Endometriosis is a chronic, inflammatory gynecological condition characterized by the ectopic growth of endometrial-like tissue, with an unclear etiology and limited treatment efficacy. Recent studies implicate the oral and gut …
