RESEARCH QUESTION: Would a properly designed educational programme offered to young women improve their awareness and fundamental knowledge of menstrual pain and endometriosis? DESIGN: A multinational cross-sectional study using a pen-and-…

OBJECTIVE: To investigate whether lesional immunostaining of putative biomarkers of recurrence and the extent of lesional and cortical fibroses are correlated with the severity of dysmenorrhea and serum antimüllerian hormone (AMH) levels in…

Objective: Despite the fact that adenomyosis is a fairly common gynecological disorder, its pathogenesis remains elusive. Several theories on the pathogenesis of adenomyosis have been proposed, but none of them has been proven experimentall…

Endometriosis in adolescence represents a specific variant of the disease with its own characteristics and, in some cases, even a possibly different pathogenesis. It has its own clinical presentation, diagnostic and therapeutic modalities. …

RESEARCH QUESTION: Can preoperative or perioperative intervention reduce the risk of recurrence of endometriosis caused by either incomplete excision or spillage and dissemination? DESIGN: A mouse model of endometriosis recurrence caused b…

Sensory and sympathetic nerves have been shown to promote the progression of endometriosis through the release of neuromediators and the lesional activation of respective receptors. The role of vagus nerves (VN) in lesional progression, how…

RESEARCH QUESTION: Do uterine procedures potentially disrupting the endometrial-myometrial interface (EMI) induce adenomyosis? DESIGN: Six prospective, randomized controlled experiments were conducted involving a total of 106 female BALB/c…

BACKGROUND: Adenomyosis is a benign uterine disorder where endometrial glands and stroma are pathologically demonstrated within the uterine myometrium. The pathogenesis involves sex steroid hormone abnormalities, inflammation, fibrosis and …

Transvaginal ultrasound (TVUS) and MRI are currently two mainstream imaging techniques used to diagnose deep endometriosis (DE) with comparable accuracy, but there is still ample room for improvement. As endometriotic lesions progress to fi…

We tested the hypothesis that enriched environment (EE), consisting of enlarged space, and increased physical activity and social interactions, hinders the development of endometriosis through attenuated adrenergic signaling, enhanced autop…

CONTEXT: Whether endometriosis is a progressive disease is a highly contentious issue. While progression is reported to be unlikely in asymptomatic deep endometriosis, progression in symptomatic deep endometriosis has recently been reported…

CONTEXT: While fibrosis in endometriosis has recently loomed prominently, the sources of myofibroblasts, the principal effector cell in fibrotic diseases, remain largely obscure. Mesothelial cells (MCs) can be converted into myofibroblasts …

Endometriosis is a hormonal disease, as well as a chronic inflammatory disease. While various immune cells are documented to be involved in endometriosis, there is a wanton lack of a bigger picture on how these cells are coordinated to work…

RESEARCH QUESTION: Do endometriotic lesions undergo endothelial-mesenchymal transition (EndoMT)? DESIGN: Lesion samples from 30 patients with ovarian endometriomas and deep endometriosis, and control endometrial tissue samples from 30 wome…

RESEARCH QUESTION: Does sodium tanshinone IIA sulfonate (STS) induce cellular senescence in endometriotic lesions and thus restrict lesional development and fibrogenesis in a recently established mouse model of deep endometriosis? DESIGN: …

Adenomyosis is used to be called endometriosis interna, and deep endometriosis is now called adenomyosis externa. Thus, there is a question as to whether adenomyosis is simply endometriosis of the uterus, either from the perspective of path…

BACKGROUND: Endometriosis is a benign gynaecological disease. Thus, it came as a complete surprise when it was reported recently that the majority of deep endometriosis lesions harbour somatic mutations and a sizeable portion of them contai…
