ObjectiveTo investigate the in vitro effect of drospirenone on human eutopic endometrial (EuSC) and ectopic endometriotic stromal cells (EcSC).DesignComparative and laboratory study. The experimental procedures were approved by the Institut…

STUDY OBJECTIVES: To evaluate the frequency of pneumothorax after laparoscopic surgery and to identify possible correlations to endometriosis. DESIGN: Retrospective review. SETTING: Tokyo University Hospital between 2006 and 2013. PATIEN…

OBJECTIVE: To identify the characteristics of cases and fibroids that will indicate which patients should undergo myomectomy to improve fertility. MATERIALS AND METHODS: We recruited patients (n=101) who had undergone myomectomy to improve…

Ovarian clear cell carcinoma (CCC) is generally associated with chemoresistance and poor clinical outcome, even with early diagnosis; whereas high-grade serous carcinomas (SCs) and endometrioid carcinomas (ECs) are commonly chemosensitive a…

PurposeTo evaluate whether laparoscopic excision of endometrioma exerts a qualitative effect on ovarian function.MethodsA retrospective analysis of oocytes retrieved in 25 cycles of 21 patients undergoing IVF treatment with controlled ovari…

Although surgical excision of endometriosis both improves pain and enhances fertility, recurrence can further exacerbate pain and reduce fertility, which in turn impacts the quality of life and increases personal as well as social costs. Th…

PROBLEM: The proportion of CD4+ T lymphocytes, Th1, Th2, Th17, and regulatory T cells in endometriosis lesions and peripheral blood are not known. METHOD OF STUDY: Lymphocytes were isolated from endometriosis lesions (n = 10) and endometriu…

DS-7423, a novel, small-molecule dual inhibitor of phosphatidylinositol-3-kinase (PI3K) and mammalian target of rapamycin (mTOR), is currently in phase I clinical trials for solid tumors. Although DS-7423 potently inhibits PI3Kα (IC50 = 15.…

Infertility caused by ovarian or tubal problems can be treated using In Vitro Fertilization and Embryo Transfer (IVF-ET); however, this is not possible for women with uterine loss and malformations that require uterine reconstruction for th…

Dienogest is a novel progestin that is highly selective for progesterone receptors and inhibits endometriosis. However, it remains unknown how the administration of dienogest to patients with endometriosis impacts on their lesion tissues. T…

Adenomyosis is a common disorder in premenopausal women that causes dysmenorrhea, pelvic pain and menorrhagia. Considering that adenomyosis is an estrogen-dependent disease, the medical treatment is based on this hormone. Effective and well…

AIM: The aim of this study was to identify factors that can predict clinical course among patients hospitalized with pelvic inflammatory disease (PID). METHODS: Ninety-three patients who needed hospitalization with a diagnosis of PID were …

BACKGROUND: Surgical site infections are potential complications following open myomectomy. These infections usually develop immediately after the surgery, and are most often located in the myometrium. Pyogenic cervical cysts are rare and h…

PROBLEM: Immune tolerance to endometriotic cells is important to promote endometriosis. Tryptophan 2,3-dioxygenase (TDO) enhances immune tolerance by catabolizing tryptophan to kynurenine. We studied whether interleukin-1β (IL-1β), a typica…

AIM: Endometriosis is a chronic inflammatory disease. Sirtuin 1 (SIRT1) plays a role in regulation of inflammation. The role of SIRT1 in endometriosis remains unknown. We here addressed the anti-inflammatory effects of SIRT1 on endometriosi…

BackgroundXanthogranulomatous inflammation is an uncommon form of chronic inflammation that is destructive to the normal tissue of affected organs. Although xanthogranulomatous endometritis and xanthogranulomatous salpingitis of the female …

BACKGROUND: Menstrual symptoms are associated with various health problems in women of reproductive age, and this may impact their quality of life. Despite this, Japanese women are likely to hesitate seeking a specialist's medical help for …

AIM: The aim of this study was to review diagnostic/therapeutic strategies of umbilical endometriosis managed in our department and evaluate the effectiveness of these strategies. METHODS: Medical records for patients with diagnosis of endo…

CONTEXT: Endometriosis is a chronic inflammatory disease in which immune response and production of estrogen in endometriotic tissues are involved in the development of the disease. Prostaglandin E2 (PGE2) stimulates aromatase (P450arom) ex…

Omega-3 polyunsaturated fatty acids (omega-3 PUFAs) play a role in controlling pathological inflammatory reactions. Endometriosis is characterized by the presence of endometrial tissue on the peritoneum and an exaggerated inflammatory envir…

PurposeAlthough studies of serum anti-Müllerian hormone (AMH) in predicting ovarian reserve are numerous, many studies utilized patients under age 40. However, the assessment of ovarian reserve is especially critical in older infertile wome…

PURPOSE: This study aimed to maximize the chance of pregnancy and provide an optimal protocol for infertile female patients of advanced reproductive age as an alternative to in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICS…

ObjectiveTo identify the frequency and assess risk factors for unexpected discovery of peritoneal endometriotic implants in patients who underwent myomectomy or hysterectomy for symptomatic uterine leiomyomas.Study designWe retrospectively …

The aim of this study is to examine the regulation of follistatin, an activin-binding protein, in endometriosis. Endometrioma stromal cells (EoSCs) were obtained from 9 patients undergoing laparoscopy of the ovarian endometrioma. In culture…

Although assisted reproductive technology (ART) is suspected to increase the risk of placenta previa, a life-threatening complication of pregnancy, the reason is poorly understood. We recruited consecutive 318 pregnancies conceived by ART i…
