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 METH…

The aim of this study was to compare intrafollicular biomarkers of thiol-redox system and chronic inflammation in infertile patients with and without endometriosis, and examine correlations between biomarkers and IVF outcomes. The study inc…

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 withou…

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…

PURPOSE: Although a variety of factors have been reported as affecting pregnancy rates after intrauterine insemination (IUI), there have been conflicting results on prognostic factors. This study aimed to determine predictive factors for pr…

Endometriosis is defined as the presence of endometrial tissue (glands and stroma) outside the uterus. About 1% of women with endometriosis have urinary tract implantations, and 84% of these cases involve the bladder. Abdominal partial cyst…

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 women…

The aim of this study is to evaluate the expression of vascular endothelial growth factor (VEGF) and its soluble receptor (sFlt-1) in peritoneal fluid (PF), peritoneal endometriotic lesions and eutopic endometrial tissues of patients with e…

Objective: The aim of this study was to assess the feasibility and safety of Single-Port Access (SPA) Laparoscopic Complete Excision (LCE) in severe endometriosis of the adnexa and pelvic peritoneum. Methods: The surgical outcomes of 40 con…

Endometriosis is usually found in pelvic cavity such as in ovary. But, endometriosis has been described in other organs, although rare, such as intestine, kidney, lung, liver, gall bladder, and pancreas. Catamenial pneumothorax is defined a…

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…

Endometriosis is an enigmatic disease characterized by development of endometrial tissue outside of the uterus, causing pain and infertility. This guideline will provide evidence based information concerning diagnosis and treatment of endom…

PurposeTo evaluate the effects of myometrial thickening on the outcomes of in vitro fertilization and embryo transfer (IVF-ET).MethodsFour hundred thirteen patients, a total of 551 IVF-ET cycles, were divided into group A (<2.00 cm), group …

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…

BACKGROUND: Non-steroidal anti-inflammatory drug (NSAID)-activated gene-1 (NAG-1) is involved in cellular processes such as inflammation, apoptosis and tumorigenesis. However, little is known about the expression and function of NAG-1 in th…
