Uterine arteriovenous fistula (UAVF) associated with adenomyosis during pregnancy is a rare, life-threatening condition. This report describes a 36-year-old woman with adenomyosis who conceived through in vitro fertilization-embryo transfer…

STUDY OBJECTIVE: To evaluate whether the type of anatomical distortion-spatial or adhesive-determines the relative performance of the energy device in complex total laparoscopic hysterectomy (TLH). DESIGN: Retrospective cohort study. SETT…

PURPOSE: To investigate the association between dendritic cell maturation deficits and pain in patients with adenomyosis and explore potential neuro-immune mechanisms. METHODS: Uterine tissues from 24 patients with adenomyosis (AM) and 15 …

AIM: To investigate the differences in lipid metabolism and obesity between patients with ovarian endometrioid carcinoma (OEC) and ovarian clear cell carcinoma (OCCC), both of which are classified as endometriosis-associated Type I ovarian …

Estetrol/drospirenone (E4/DRSP) is a combined oral contraceptive noted for its minimal hemostatic impact compared to ethinyl estradiol-based preparations. However, real-world thrombotic risk data in patients with significant comorbidities r…

AIM: To evaluate the incidence of tubo-ovarian abscess (TOA) in patients with ovarian endometrioma (OE) undergoing infertility treatment and to describe treatment approaches and clinical outcomes, including transvaginal ultrasound-guided dr…

AIM: To investigate the mechanisms of histone deacetylase (HDAC) 10 inhibitors (HDAC10Is) action in endometriosis and the target molecules of HDAC10Is. METHODS: We assessed the effects of HDAC10Is, tucidinostat and TH34, on the proliferati…

OBJECTIVE: Despite growing recognition of adenomyosis as a significant gynecological condition, standardized hysteroscopic diagnostic criteria remain lacking. This study aimed to systematically characterize endometrial hysteroscopic finding…

AIM: To investigate whether the etiology of diminished ovarian reserve (DOR) independently influences outcomes of assisted reproductive technology (ART). METHODS: This multicenter, retrospective cohort study was a secondary analysis of a n…

AIM: Endometriosis affects 6%-10% of women of reproductive age and is associated with chronic pelvic pain, infertility, and impaired quality of life. The endometriosis fertility index (EFI) predicts spontaneous pregnancy postoperatively, bu…

AIM: This exploratory pilot study aimed to assess the preliminary clinical effects of leuprorelin acetate microspheres for injection [gonadotropin-releasing hormone agonist (GnRH-a)] combined with levonorgestrel-releasing intrauterine syste…

OBJECTIVE: To identify the risk factors associated with postoperative recurrence of unusual (special-type) uterine smooth muscle neoplasia (USMN) and to construct and interpret a machine-learning model for recurrence risk. METHODS: We carr…

In Japan, the microwave endometrial ablation system (MEA, Microsulis PLC, Waterlooville, UK) is the most widely used device for endometrial ablation and is considered a minimally invasive, uterus-preserving treatment for menorrhagia. Althou…

Borderline ovarian tumors primarily affect younger women and are associated with favorable prognosis, making fertility-sparing surgery a viable option. However, owing to recurrence and malignant transformation risks, careful monitoring is r…

OBJECTIVES: In this study, we aimed to compare the clinical characteristics of cellular leiomyoma (CL) with those of typical uterine leiomyoma (UL) and explore recurrence risk factors in patients with CL myomectomy. STUDY DESIGN: In this r…

Patients with endometriosis are at a high risk of developing pelvic inflammatory disease. This case series presents three cases of colo-ovarian fistulas associated with endometriosis, highlighting the potential for conservative management i…

PURPOSE: Adenomyosis is a common uterine disease second only to uterine leiomyoma. Its management often requires medical treatment. However, practically no drug has ever been developed exclusively for adenomyosis. Development of non-hormona…

AIM: Endometriosis is a chronic gynecological condition characterized by persistent inflammation and frequently associated with dysmenorrhea and infertility. The success rate of assisted reproductive technology (ART) in individuals with end…

Primary umbilical endometriosis (PUE) is a rare form of extragenital endometriosis, accounting for only 0.5%-1% of all endometriosis cases. Surgical excision is the primary treatment; however, it often results in disfigurement of the umbili…

AIM: Endometriosis is an estrogen-dependent disease with unclear pathogenesis. Recent evidence suggests that ferroptosis plays an important role in the development of endometriosis. In this study, we aimed to explore whether membrane-bound …

Cesarean scar defect (CSD) is a long-term complication of cesarean section (CS). However, its risks for perimenopausal women remain unclear. We present a rare case of CSD involving hematometra in a perimenopausal woman, which led to emergen…

BACKGROUND: Endometriosis is a chronic inflammatory condition afflicting women of reproductive age. Our study aims to clarify the function and mechanism of insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1) and high mobility grou…

AIM: This study aimed to compare clinical characteristics and evaluate diagnostic biomarkers in ovarian endometriosis, with a focus on thyroid autoimmunity associations. METHODS: A retrospective analysis of 885 patients (441 ovarian endome…

OBJECTIVES: This study investigates iron metabolism characteristics in patients with ovarian endometriosis (EMs) and infertility. METHODS: A case-control study was conducted involving 76 infertility patients treated at Baise People's Hospi…
