Formalin-fixed paraffin-embedded (FFPE) tissues represent an invaluable resource for both basic and clinical research due to their stable preservation of tissue architecture and molecular integrity. Multiplex immunofluorescence (mIF) using …

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…

Uterine fibroids, or leiomyomas, are benign uterine tumors with a lifetime prevalence of approximately 75%. While only a minority become symptomatic, their impact on quality of life remains profound owing to heavy menstrual bleeding, bulk s…

Uterine fibroids (leiomyomas) and adenomyosis are among the most common benign gynecological conditions affecting women of reproductive age. These disorders are frequently associated with abnormal uterine bleeding, pelvic pain, pressure sym…

Background/Objectives: The assessment of endometriosis (EMS)-associated pain is important, but only very few studies address the potential use of questionnaires for non-invasive prediction of the disease. Methods: In a prospective observati…

Chronic pelvic pain (CPP), a debilitating condition affecting an estimated 25% of women worldwide, represents a significant yet understudied global health crisis. Existing research is limited and likely fails to capture the true impact of C…

Postoperative adhesions represent a major medical challenge and are associated with serious health and economic consequences. 4DryField® PH (PlantTec Medical GmbH, Lueneburg, Germany) is a starch-based medical device designed both to preven…

Anogenital distance (AGD) is regarded as a potential biomarker for endometriosis, and a measurement on MRI images has been found to be promising. This study aimed to evaluate the measurement of AGD on MRI to predict the surgical diagnosis o…

The changes in endometrial cells, both in the eutopic endometrium of patients with and without endometriosis and in lesions at ectopic sites, are frequently described and often compared to tumorigenesis. In tumorigenesis, the concept of "se…

BACKGROUND: Membrane type-matrix metalloproteinases (MT-MMPs) are a subgroup of the matrix metalloproteinases (MMPs) family and are key molecules in the degradation of the extracellular matrix. Membrane type-1 matrix metalloproteinase (MT1-…

Objectives The purpose of this investigation was to evaluate the inter- and intraobserver variability of the updated #Enzian classification of endometriosis on MRI and to evaluate the influence of reader experience on interobserver concorda…

Several current guidelines recommend imaging in the diagnostic work-up of deep infiltrating endometriosis (DIE). The purpose of this retrospective diagnostic test study was to evaluate the diagnostic accuracy of MRI compared to laparoscopy …

In the pathogenesis of endometriosis, the differences between the eutopic and ectopic endometrium as well as between the eutopic endometrium with and without endometriosis are repeatedly pointed out. Various mechanisms have been suggested t…

OBJECTIVE: To evaluate blood-based biomarkers to detect endometriosis and/or adenomyosis across nine European centers (June 2014-April 2018). METHODS: This prospective, non-interventional study assessed the diagnostic accuracy of 54 blood-b…

OBJECTIVES: Are other pain symptoms in addition to dysmenorrhea, dyspareunia, dyschezia, dysuria, and chronic pelvic pain correlated to endometriosis and suitable for a clinical prediction model? METHODS: We conducted a prospective study fr…

Abstract Introduction Endometriosis significantly reduces patientsʼ quality of life and is additionally a burden on healthcare and social security systems. There are currently no quality indicators for the treatment of endometriosis. The ca…

The TGF-β superfamily members, activins and inhibins, are mainly involved in cell proliferation, cell survival, invasion, immune surveillance, and lesion growth in endometriosis. Herein, we investigated the modulation of the TGF-β type III …

Claudins, as the major components of tight junctions, are crucial for epithelial cell-to-cell contacts. Recently, we showed that in endometriosis, the endometrial epithelial phenotype is highly conserved, with only minor alterations. For ex…

Matrix metalloproteinases (MMPs) play an important role in menstruation and endometriosis; however, the membrane-type matrix metalloproteinases (MT-MMPs) are not well studied in endometriosis and adenomyosis. We analyzed MT2-MMP (MMP15) and…

Chronic pelvic pain (CPP) affects the female population in about 4-15 % after all gynecological treatments. Endometriosis or endometriosis treatment represent a frequent reason for CPP. After multiple operations a surgery-associated morbidi…

Endometriosis is characterized by the presence of ectopic endometrium most often in the pelvis. The transforming growth factor-beta (TGF-β) superfamily is also involved in the pathogenesis; however, betaglycan (BG, syn. TGF-β type III recep…
