PurposeThis study aimed to develop international expert consensus statements on chronic endometritis (CE) through a comprehensive literature review of existing evidence and a modified Delphi approach.MethodsTen panelists of the Japan Societ…

ObjectivesTo delineate the hysteroscopic findings of placental site nodule and plaque (PSNP) and determine its association with secondary infertility and chronic endometritis (CE).Materials and methodsWe performed a retrospective cohort stu…

PROBLEM: Despite abundant reports on the risk role of uterine outflow tract obstruction in endometriosis, information on the occurrence of endometriosis in women with Chlamydia trachomatis infection causing fallopian tube obstruction is unk…

[Background] As its name indicates, anti-Müllerian hormone (AMH) is primarily found as an inhibitor of Müllerian duct in male fetus. On the other hand, AMH may act as a mediator of Müllerian duct derived female tissue, such as endometrium i…

BACKGROUND: Autoimmune reactions and subsequent inflammation may underlie spermatogenic dysfunction and endometriosis-related infertility. The aim of this study is to identify disease-specific antigens in immune complexes (ICs) in seminal p…

BACKGROUND: Endometriosis is a multifactorial disease that mainly affects women of reproductive age. The exact pathogenesis of this disease is still debatable. The role of bacterial endotoxin (lipopolysaccharide, LPS) and Toll-like receptor…

Endometrioma is one of the main pathologies of endometriosis, though its pathogenesis still remains enigmatic. Ovarian reserve is defined as the number and quality of the follicles left in the ovary at any given time. The cause of infertili…

ObjectiveEndometriosis is commonly believed to originate from functionalis endometrium and adenomyosis from basalis endometrium. Due to the lack of enough information, we investigated the biological differences between these two layers of e…

After reduction of the incarceration during surgery for incarcerated hernia, intestinal blood flow (IBF) and the need for bowel resection must be evaluated. We report the case of a patient with incarcerated umbilical hernia in whom the bowe…

ObjectiveIncreased intrauterine microbial colonization by bacteria culture method and occurrence of endometritis have been reported in women with endometriosis. Here we investigated microbial colonization in intrauterine environment and cys…

ObjectiveA prominent stress reaction in the pelvis of women with endometriosis and the role of human heat shock protein 70 (HSP70) in inflammation and the growth of endometriosis has been recently demonstrated. We report here expression of …

Adenomyosis is commonly believed to arise from the basalis endometrium. As an estromedin growth factor, hepatocyte growth factor (HGF) exhibits multiple functions in endometriosis, a disease commonly believed to arise from the functionalis …

Endometriosis is a multifactorial disease mostly affecting women of reproductive age. An additive effect between inflammation and stress reaction on the growth of endometriosis has been demonstrated. Here we investigated the combined effect…

ObjectivesHuman heat shock protein 70 (HSP70) has been reported to enhance Toll-like receptor 4-mediated pelvic inflammation and growth of endometriotic cells. However, information on tissue expression of HSP70 before and after treatment wi…

ObjectiveTo evaluate the effects of endometriomas on the regulation of early follicular development.DesignHistologic analysis of prospectively collected biopsy samples.SettingResearch unit in a university hospital.Patient(s)Women <40 years …

STUDY QUESTION: Is there any risk of intra-uterine bacterial colonization and concurrent occurrence of endometritis in women with endometriosis? SUMMARY ANSWER: An increase in intra-uterine microbial colonization and concurrent endometritis…

study question: Is there any combined effect between inflammation and stress reaction on Toll-like receptor 4 (TLR4)-mediated growth of endometriotic cells? summary answer: A combined effect of local inflammation and stress reaction in the …

STUDY QUESTION: Is there any occurrence of hidden (occult) endometriotic lesions in normal peritoneum of women with and without visible endometriosis? SUMMARY ANSWER: We detected a slightly higher occurrence of occult microscopic endometrio…

Endometriosis is an estrogen-dependent chronic inflammatory condition associated with variable degrees of pelvic pain and infertility. Studies have showed that the growth and progression of endometriosis continue even in ovariectomized anim…

STUDY QUESTION: Is the occurrence of pelvic pain in women with ovarian endometrioma associated with coexisting peritoneal lesions (PLs)? SUMMARY ANSWER: Pelvic pain in women with ovarian endometrioma is usually associated with coexisting PL…

STUDY QUESTION: Can prostaglandin E(2) (PGE(2)) in menstrual and peritoneal fluid (PF) promote bacterial growth in women with endometriosis? SUMMARY ANSWER: PGE(2) promotes bacterial growth in women with endometriosis. WHAT IS KNOWN ALREADY…

To define the role of surgery in the treatment of endometriomas, we review the literature available via PubMed and cross-reference the published data. We analyze the arguments in favor of and against surgical treatment of endometriomas and …

We measured serum anti-Müllerian hormone levels before and after surgery in women undergoing unilateral and monolocular cystectomy for benign ovarian diseases. Comparing to control benign cysts, we found a significant decline in serum anti-…

ObjectiveTo evaluate the adverse effects of endometriomas on ovarian reserve.DesignAnalysis of prospectively collected biopsy samples.SettingGynecology research unit in a university hospital.Patient(s)Women younger than age 35 years with en…

BACKGROUND: We recently demonstrated the effect of gonadotrophin-releasing hormone agonist (GnRHa) on tissue inflammation, angiogenesis and apoptosis in endometriosis, adenomyosis and uterine myoma. Here, we investigated expression of GnRH …
