PurposeTo estimate the prevalence and correlates of low serum 25-hydroxyvitamin D [25(OH)D] among women attending infertility clinics in Japan.MethodsWe conducted a multicenter cross-sectional study of 17 261 women with measured 25(OH)D. De…

Only a few human ovarian endometrioid carcinoma cell lines are currently available, partly due to the difficulty of establishing cell lines from low-grade cancers. Here, using a cell immortalization strategy consisting of i) inactivation of…

Ovarian endometrioid carcinoma (OEC) accounts for ~10% of epithelial ovarian cancers and displays broad morphologic diversity that complicates diagnosis and grading. Recent data show that the endometrial cancer molecular taxonomy (DNA polym…

PurposeTo evaluate the impact of Endometrial Microbiome Metagenomic Analysis and Analysis of Infectious Chronic Endometritis (EMMA & ALICE) on pregnancy outcomes following recommended treatments in women with recurrent implantation failure …

Epithelial ovarian cancer (EOC) is widely recognized as the most lethal gynecological malignancy; however, its early-stage detection remains a considerable clinical challenge. To address this, we have introduced a new method, named Comprehe…

A human ovarian clear cell carcinoma cell line was established from a 46-year-old Japanese woman. That line, designated MTC-22, has proliferated continuously for over 6 months in conventional RPMI 1640 medium supplemented with 10% foetal bo…

PurposeTo evaluate clinical outcomes after endometrial receptivity analysis (ERA).MethodsThis was a multicenter, retrospective cohort study involving 861 women who underwent ERA testing at certified fertility clinics in Japan, and who recei…

Homocysteine is an amino acid naturally produced in the body and metabolized via the methionine cycle. High homocysteine levels can increase the risk of infertility and pregnancy complications, such as preeclampsia, preterm delivery, miscar…

Background and Objectives: Vasa previa (VP) is a significant perinatal complication that can have serious consequences for the fetus/neonate. Velamentous cord insertion (VCI) is a crucial finding in prenatal placental morphology surveillanc…

PurposeOur aim is to make an ideal embryo culture medium close to human oviduct fluid (HOF) components, and to evaluate the quality of this medium with embryo quality and clinical outcomes in assisted reproductive technology (ART) by a pros…

OBJECTIVE: To examine the safety and feasibility of total laparoscopic retrograde hysterectomy (TLreH) in patients with obliterated cul-de-sac due to severe endometriosis. STUDY DESIGN: This retrospective case-control observational study w…

•A 56-year-old woman developed two seromucinous borderline tumors 26 years apart.•The second cyst was diagnosed as a seromucinous borderline tumor associated with pelvic endometriosis.•The first ovarian cancer was re-diagnosed as an ovarian…

Patients with cervical adenocarcinoma (AC) and adenosquamous carcinoma (ASC) have a poorer prognosis than those with squamous cell carcinoma (SCC). Erb-b2 receptor tyrosine kinase 3 (HER3) is a member of the epidermal growth factor receptor…

Endometriosis-related cervical neoplasms are rare, and their clinicopathological features and association with human papilloma virus infection are unclear. A postmenopausal woman with recently diagnosed cervical adenocarcinoma was referred …

BACKGROUND: Endometriosis is considered to be the most intractable cause of female infertility. Administering any type of treatment for endometriosis before in vitro fertilization and embryo transfer (IVF-ET) is an important strategy for im…

Study objectivesThe aim of this study is to evaluate the effects of vaginal estriol therapy in total laparoscopic hysterectomy (TLH) with gonadotropin-releasing hormone agonist (GnRH-a) treatment.DesignRetrospective analysis.Design classifi…

A solitary pelvic tumor after treating a primary endometriosis-related neoplasm is usually considered a recurrence but may actually be a primary endometriosis-related peritoneal neoplasm. A Japanese woman in her late 60s was referred to our…

AimTo investigate the differences in leiomyoma pathophysiology by patient age at the time of surgery and the possible significance of postmenopausal uterine leiomyomas, particularly variants.MethodsWe retrospectively reviewed data from 471 …

) levels suggest the presence of potential follicles. The EFS is a rare condition with an incidence of 0.5-7 % of women undergoing IVF treatments. Although there are many hypotheses as to the cause of EFS, including advanced ovarian age, dr…

We report a rare case in which a cystic lesion in the cervix, caused by endometriosis, resulted in a massive vaginal hemorrhage. Cervical endometriosis is relatively common and is usually considered a mild condition. However, we report a ca…

Background : Decreased conception rate with advanced maternal age has been well demonstrated. Although this decline becomes apparent at 35 years of age, and accelerates rapidly in women over 40 years of age, we are able to report pregnancy …

The expression of vascular endothelial growth factor (VEGF) and cyclooxygenase-2 (COX-2) were immunohistochemically examined in both pelvic and extrapelvic endometriotic lesions. Different expressions of VEGF and COX-2 were observed in both…

A 30-year-old female had twice experienced right pneumothorax within 2 months that was related to the onset of menstruation, suggesting catamenial pneumothorax. Right thoracoscopy revealed the presence of "blue berry spots" and pinhole at t…

Defects in the cell-mediated immune system may play a role in the pathogenesis or progression of pelvic endometriosis. Possible mediators include macrophages, interleukins-1 and -6, and tumor necrosis factor-alpha. More recent work points t…

ObjectiveWe evaluated the secretion of hepatocyte growth factor by eutopic endometrial stromal cells in vitro.DesignEutopic endometrial stromal cells were isolated and the culture supernatants were collected after 48 hours of incubation. Th…
