INTRODUCTION: The Senhance Surgical System is the second robotic surgical platform approved for laparoscopic procedures in Japan. It is unique compared to other systems, offering eye-tracking camera control, haptic feedback, and reusable in…

BACKGROUND: Women's health is significantly influenced by the appropriate and timely secretion of female sex steroid hormones. Consequently, awareness of hormonal fluctuations at various life stages is crucial. In 2016, the Japanese Ministr…

BACKGROUND: MicroRNAs (miRNAs) regulate gene expression and are emerging as biomarkers for epithelial ovarian cancer (EOC). We evaluated the diagnostic performance of serum miR-200c-3p and miR-6134, alone and in combination with established…

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…

Among epithelial ovarian cancer, clear cell carcinoma is common for chemo-resistance and high mortality. This cancer arises from benign ovarian endometrioma (OE), which is a high oxidative stress environment due to the cystic retention of m…

INTRODUCTION: Anti-β2-glycoprotein I (β2GPI)/human leukocyte antigen (HLA)-DR antibodies may be a risk factor for recurrent pregnancy loss (RPL). The therapeutic modality for women with RPL and anti-β2GPI/HLA-DR antibody positivity has not …

Anti-β2-glycoprotein I/HLA-DR (anti-β2GPI/HLA-DR) antibody has been reported to be associated with antiphospholipid syndrome and recurrent pregnancy loss (RPL). We conducted a prospective multicenter cross-sectional study aimed at evaluatin…

OBJECTIVES: Although adenomyosis is reportedly associated with adverse pregnancy outcomes, clinical factors related to the high risk of obstetric complications are unclear. This study aimed to elucidate the characteristics of adenomyosis le…

Multilocular cystic leiomyomas rarely develop following myomectomy. To the best of our knowledge, there are no published reports on recurrent multilocular cystic leiomyoma following myomectomy. We here present such a case. A 45-year-old wom…

Intra-ovarian local factors regulate the follicular microenvironment in coordination with gonadotrophins, thus playing a crucial role in ovarian physiology as well as pathological states such as polycystic ovary syndrome (PCOS). One recentl…

OBJECTIVE: Long-term administration of dienogest, which is known to have effect on bone mineral density, is frequently done in patients with endometriosis and adenomyosis, but a few studies focused on the bone mineral density changes after …

HELLP syndrome is sometimes followed by massive bleeding, leading to DIC. In cases of intra-abdominal compartment syndrome due to massive intra-abdominal bleeding after cesarean section, if preeclampsia and partial HELLP syndrome persist, h…

We present a case of hemorrhagic shock occurred during dienogest therapy for uterine adenomyosis which necessitated an emergency hysterectomy. The patient was a 45-year-old woman with adenomyosis. Magnetic resonance imaging showed type I ad…

Administration of Dienogest prior to hysteroscopic polypectomy is empirically performed, but the physiological effects of Dienogest on endometrial polyps are unclear. We aimed to investigate the effects of Dienogest on the proliferation and…

Human endometrium is a highly regenerative and dynamic tissue that undergoes cyclic changes during menstrual cycle. It has been reported that endometrial epithelium contains a population of progenitor/stem cells. Increasing amount of eviden…

When the presence of endometriotic lesions are not evident by hematoxylin and eosin staining, CD10 is used to highlight and confirm the presence of endometriotic stroma. However, CD10 is not specific only to the endometrial stroma but is al…

In cases of extragenital endometriosis or microscopic endometriosis lesions, pathological diagnosis can be challenging because endometriotic stroma and glands represent only a minor component of fibrotic endometriotic lesions. For better ac…

OBJECTIVES: To evaluate the anti-inflammatory and anti-angiogenetic effects of Tokishakuyakusan (TSS), a traditional Japanese medicine (Kampo), and its ingredients, ferulic acid (FA) and paeoniflorin (PA) on endometriotic stromal cells (ESC…

Previous studies have suggested that histone methylation can modulate carcinogenesis and cancer progression. For instance, the histone methyltransferase SET and MYND domain containing 2 (SMYD2) is overexpressed in several types of cancer ti…

Non-hormonal therapeutic strategies for endometriosis are needed. The aim of this study was to characterize the effects of prostaglandin (PG)E2 receptor inhibitors to explore their potential as novel therapeutic strategies for endometriosis…

Endometriosis exerts detrimental effects on ovarian physiology and compromises follicular health. Granulosa cells from patients with endometriosis are characterized by increased apoptosis, as well as high oxidative stress. Endoplasmic retic…

This study aimed to evaluate the attitudes of male and female members of the public toward uterus transplantation (UTx), surrogacy, and adoption in Japan via a web-based survey. One thousand six hundred participants were recruited with equa…

AIM: This study aimed to describe the clinical presentation, diagnostic evaluation, and operative or medical management of inguinal endometriosis. METHODS: In this study, we retrospectively reviewed 20 cases of inguinal endometriosis in ou…

BACKGROUND: The recurrence rate after unilateral salpingo-oophorectomy (USO) for unilateral endometrioma has not been reported. We evaluated the rate of and risk factors for endometrioma recurrence after USO. METHODS: In this retrospective…

CONTEXT: The ovarian reserve is reduced in patients with endometriosis. We hypothesize that the phosphatidylinositol 3-kinase (PI3K)-phosphatase and tensin homolog deleted on chromosome 10 (PTEN) Akt-Forkhead box O (Foxo3) pathway is involv…
