BACKGROUND: Adenomyosis is a common gynecological disease and a major contributor to dysmenorrhea that substantially reduces the quality of life of the affected. Dienogest has emerged as a promising drug for treating adenomyosis. A few syst…

BACKGROUND: The nature and functions of the innermost layer of the myometrium, which is located immediately below the endometrium, coined the "junctional zone" (JZ), continue to be the subject of debate. The role and significance of the JZ …

The authors regret “We are very sorry for the careless printing mistake in the proper alignment of case numbers in Table 2, Table 3 of the mentioned article. These case numbers [(n = 25) and (n = 782)] should be read above the line and belo…

OBJECTIVE: We examined the prevalence and risk factors in association with neonatal uterine bleeding (NUB) by retrospective search of contemporary and historical medical records and investigated the possible association between the history …

The innate and adaptive immune systems are the two key branches that determine host protection at all mucosal surfaces in human body, including the female reproductive tract. The pattern recognition receptors within the host that recognize …

Gonadotrophin-releasing hormone (GnRH) antagonists have been demonstrated to reduce endometriosis-associated pain. Because of the hypo-oestrogenic state they induce, however, higher dosages of GnRH antagonists are not recommended for used l…

BackgroundA potential concern has been raised regarding fertility and reproductive outcome during the Covid-19 pandemic with growing stress and anxiety. However, information on the association between tissue stress reaction and expression p…

BACKGROUND: The occurrence of vaginal bleeding in early neonatal life has been observed for centuries and was considered a consequence of the sudden drop in circulating hormones following birth. As such, neonatal uterine bleeding was dismis…

BACKGROUND: It has been hypothesized that the origin of early-onset endometriosis could be from endometrial mesenchymal stem cells (eMSCs) in neonatal uterine blood (NUB). There is no information on the possible mechanistic basis linking an…

High-intensity focused ultrasound (HIFU) has emerged as a promising uterus-sparing and possibly fertility-sparing treatment modality for women with adenomyosis, especially those who desire to conceive. We conducted this systematic review an…

BACKGROUND: Women with endometriosis have been shown to have a reduced vagal tone as compared with controls and vagotomy promoted while vagus nerve stimulation (VNS) decelerated the progression of endometriosis in mice. Extensive research a…

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-…

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 questionCan preoperative or perioperative intervention reduce the risk of recurrence of endometriosis caused by either incomplete excision or spillage and dissemination?DesignA mouse model of endometriosis recurrence caused by spil…

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 questionDo uterine procedures potentially disrupting the endometrial-myometrial interface (EMI) induce adenomyosis?DesignSix prospective, randomized controlled experiments were conducted involving a total of 106 female BALB/c and 1…

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 …

BACKGROUND: \nAdenomyosis 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 an…

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…

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 questionDo endometriotic lesions undergo endothelial-mesenchymal transition (EndoMT)?DesignLesion samples from 30 patients with ovarian endometriomas and deep endometriosis, and control endometrial tissue samples from 30 women with…

Research questionDoes 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?DesignProspe…
