Background/Objectives: Oxidative stress is a critical factor in the development and progression of endometriosis. Granulosa cells, which reside near oocytes in follicles, exhibit steroidogenic activity, and, consequently, influence oocyte q…

Cell membrane ion channels have important roles in cell migration during cancer development and metastasis. Although endometriosis is a benign gynecological disease, some migration and invasion characteristics of endometriosis are similar t…

The aim of this study was to determine predictive factors for pregnancy and assess the cumulative pregnancy rate (CPR) and live birth rate (CLBR) in subfertile couples undergoing timed intercourse (TI) using ultrasound. This retrospective c…

BACKGROUND: This study aimed to evaluate the compatibility of robotic single-site (RSS) myomectomy in comparison with the conventional robotic multi-port (RMP) myomectomy to achieve successful surgical outcomes with reliability and reproduc…

Endometriosis is a common gynecologic disorder characterized by chronic pelvic pain, dysmenorrhea, and infertility. Although this condition places significant financial burden on the healthcare system and negatively affects patient's qualit…

Uterine leiomyoma is found in ~50-80% of women of a reproductive age and is the most common reason for hysterectomy. Recently, posttranscriptional gene silencing by microRNAs (miRs) has been reported as a mechanism for regulating gene expre…

OBJECTIVE: This study was aimed at identifying a correlation between polycystic ovarian morphology (PCOM) and the severity of primary dysmenorrhea in young Korean women. METHODS: A total of 592 patients who visited a tertiary hospital from…

Aquaporins (AQPs) are involved in cell migration, proliferation and carcinogenesis in tumor development and physiologic inflammatory processes, but their associations with endometriosis have not been fully evaluated. In this study, tissue s…

Estrogen affects endometrial cellular proliferation by regulating the expression of the c-myc gene. B-cell translocation gene 1 (BTG1), a translocation partner of the c-myc, is a tumor suppressor gene that promotes apoptosis and negatively …

Background: Repair of DNA double strand break (DSB) is an important mechanism for maintaining genetic stability during a DNA damage event. Although, a growing body of recent evidence suggests that DNA DSBs and related repair mechanisms may …

AIMS: Our objective was to predict natural pregnancy after endometriosis surgery using the endometriosis fertility index (EFI). METHODS: A retrospective medical records review was conducted, examining patients surgically treated for endome…

OBJECTIVE: This study aimed to identify factors that affect in vitro fertilization (IVF) outcomes in women with diminished ovarian reserve (DOR). METHODS: We reviewed 99 IVF cycles in 52 women with DOR between September 2010 and January 20…

OBJECTIVE: The aim of this study was to evaluate the effectiveness of postoperative levonorgestrel-releasing intrauterine system (LNG-IUS) insertion after gonadotropin-releasing hormone agonist (GnRH-a) treatment for preventing endometrioti…

To investigate the effects of trichostatin A (TSA) on nonsteroidal anti-inflammatory drug-activated gene 1 (NAG-1) expression and apoptosis in human endometriotic stromal cells (HESCs), ectopic endometrial tissues were obtained from 15 pati…

OBJECTIVE: To analyze the diagnostic profiles and treatment outcomes of patients with thoracic endometriosis at a university hospital. METHODS: A retrospective review of medical records was performed for patients diagnosed with thoracic en…

PURPOSE: This study aimed to evaluate the prognostic value of each component of the revised American Fertility Society (rAFS) classification system for the first recurrence of endometriosis after conservative laparoscopy. MATERIALS AND MET…

Adenosquamous carcinoma (ASC) is a rare tumor of the liver, which carries a poor prognosis. It has been reported mostly in the form of case studies. Recently, we experienced a case of primary ASC of the liver that has been preoperatively co…

OBJECTIVE: The aim of this study is to validate and investigate the clinical value of urinary enolase I in patients with endometriosis. METHODS: Urine samples of 39 patients with histologically confirmed endometriosis and 20 patients witho…

OBJECTIVE: Although the levonorgestrel-releasing intrauterine system (LNG-IUS) is effective in reducing the recurrence of endometriosis-associated pain, its efficacy in preventing endometrioma recurrence is questionable. We compared the eff…

PROBLEM: We investigated the association of COX -2 gene-765G/C polymorphism and risk of advanced-stage endometriosis in Korean women. METHOD OF STUDY: This study consisted of 268 women with advanced-stage endometriosis and 242 control wome…

BACKGROUND: Recently, proteomic technologies have demonstrated that several proteins are differently expressed in various body fluids of patients with endometriosis compared with those without this condition. The aim of this study was to in…

Because energy production involves oxidative phosphorylation, mitochondria are major sources of reactive oxygen species in the cell. Recent findings indicate that mitochondrial DNA (mtDNA) variants may play a role in the etiology of certain…

The levonorgestrel-releasing intrauterine system (LNG-IUS) is effective in the treatment of dysmenorrhea associated with adenomyosis. However, the mechanism of pain relief of LNG-IUS in patients with adenomyosis is unclear. We aimed to inve…
