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…

Expression and possible role of non-steroidal anti-inflammatory drug-activated gene-1 (NAG-1) in the human endometrium and endometriosis

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…

Oxidative stress has been proposed as a potential factor associated with the establishment and progression of endometriosis. Although a few studies have shown possible mechanisms which may play roles in development, progression of endometri…

The objective of this study was to evaluate whether robotic tubal reanastomosis after segmental resection of tubal pregnancy is a feasible means of preserving tubal integrity and natural fertility in those with compromised contralateral tub…

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…

Although the pathophysiology of adenomyosis has not been clarified, it is thought to be related to ectopic endometrium, which depends on hormonal regulation. The levonorgestrel-releasing intrauterine system (LNG-IUS) is effective for the me…

OBJECTIVES: Lymphangiogenesis may be involved in the pathogenesis of adenomyosis. We investigated the lymphatic vessels of patients with adenomyosis, including those treated with levonorgestrel-releasing intrauterine system (LNG-IUS). METH…

PURPOSE: To evaluate the efficacy of minimal stimulation using discretely administered gonadotropin combined with clomiphene citrate (CC) or letrozole (LTZ) for intrauterine insemination (IUI) cycles. MATERIALS AND METHODS: Total 257 IUI c…

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…

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 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…

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…

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…

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…

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…
