Despite widespread rhFSH use in infertile women undergoing ART, real-world comparative data on its effectiveness and safety across different rhFSH types remain limited. Using the HIRA claims database, we included 10,684 women aged 20-39 wit…

PURPOSE: To investigate whether the number of oocytes retrieved after controlled ovarian stimulation (COS) for fertility preservation (FP) can be predicted using serum anti-Müllerian hormone (AMH) levels in adolescent and young adult (AYA) …

This study aimed to investigate the efficacy and safety of using optimized parameters obtained by computer simulation for ultrasound-guided high-intensity focused ultrasound (HIFU) treatment of uterine adenomyosis in comparison with convent…

BACKGROUND: Female infertility is a crucial problem with significant implications for individuals and society. In this study, we explore risk factors for infertility in Korean women. METHODS: A total of 986 female patients who visited six …

The prevalence of genital human papillomavirus (HPV) in women with endometriosis has never been reported in a national representative survey. We aimed to investigate the association of endometriosis with the prevalence of HPV. We analyzed t…

OBJECTIVE: The risk of developing endometrial hyperplasia after diagnosis of endometriosis has not been determined. Moreover, the risk of endometrial cancer associated with endometriosis is unclear. This nationwide population-based study in…

Sex steroid hormones play a major role in bone homeostasis. Therefore, the use of sex hormones or drugs may increase the risk of osteonecrosis of the jaw (ONJ), a complication caused by damaged bone homeostasis. However, few are known the i…

OBJECTIVE: This study aimed to investigate sperm motility and its changes after preparation as predictors of pregnancy in intrauterine insemination (IUI) cycles. METHODS: In total, 297 IUI cycles from January 2012 to December 2017 at a sin…

PURPOSE: To elucidate the correlation between ovarian reserve and the incidence of ectopic pregnancy (EP) following in vitro fertilization and embryo transfer (IVF/ET) cycles. MATERIALS AND METHODS: In this observational study, 430 fresh I…

Endometriosis is one of the most common diseases in reproductive ages, and it affects patients' quality of life and fertility. However, few Korean guidelines are available for the evaluation and management of endometriosis. Korean Society o…

OBJECTIVE: To compare the in vitro fertilization (IVF) outcomes between women with diminished ovarian reserve (DOR) after endometrioma operation and women with DOR without ovarian surgery. METHODS: This retrospective case-control study inc…

Artificial uterus using endometrium implant can be a novel treatment strategy for infertile women with refractory endometrial dysfunction. At early pregnancy, the function of uterine endometrial cells for the communication between the conce…

OBJECTIVE: Ovarian reserve tests are commonly used to predict ovarian response in infertile patients undergoing ovarian stimulation. Although serum markers such as basal follicle-stimulating hormone (FSH) or random anti-Müllerian hormone (A…

Endothelial nitric oxide synthase gene Glu298Asp polymorphism is associated with advanced stage endometriosis

OBJECTIVE: To estimate the incidence of, and identify risk factors for, spontaneous expulsion of the levonorgestrel-releasing intrauterine system (LNG-IUS). METHODS: Pre-insertion characteristics for 481 women who received the LNG-IUS at a…

OBJECTIVE: Genetic factors are known to be associated with the development and progression of endometriosis, but the genes related to endometriosis have not been defined. Insulin-like growth factor binding proteins (IGFBPs) are believed to …

PURPOSE: To evaluate the relationship between endometriosis and polymorphisms in the genes encoding tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), TRAIL receptor (DR) and osteoprotegerin (OPG) and their serum levels …

PROBLEM: To investigate the association between polymorphisms of the interleukin-1 (IL-1) family genes and endometriosis in Korean women. METHOD OF STUDY: In this case-control study, the IL-1α -889C>T, IL-1 receptor antagonist (IL-1RA) 86-…

OBJECTIVES: To evaluate the relationship between endometriosis and polymorphisms in insulin-like growth factors (IGFs) and IGF-I receptor genes. STUDY DESIGN: In a case-control study, 128 women with endometriosis and 108 control women were…

PROBLEM: To investigate the association between endometriosis, transforming growth factor-β1 (TGFB1) gene polymorphisms, and serum TGF-β1 levels in Korean women. METHOD OF STUDY: The -509C/T, 868T/C, 913G/C and 979G/A polymorphisms of the …

BACKGROUND: Altered expression of endothelial nitric oxide synthase (eNOS) has been reported to be involved in the development of endometriosis. The genotypes of eNOS gene (NOS3) may be responsible for variation in its enzymatic activity as…

OBJECTIVES: To investigate the associations between endometriosis and the G(-2518)A polymorphism of monocyte chemotactic protein-1 (MCP-1), and serum and peritoneal fluid MCP-1 levels in Korean women. STUDY DESIGN: The G(-2518)A polymorphi…

PROBLEM: The aim of this study was to investigate the relationship between the polymorphisms of the tumor necrosis factor-alpha (TNT-alpha) and TNF receptor (TNFR) genes and serum levels of TNF-alpha and its soluble receptor (sTNFR) in Kore…

OBJECTIVE: To evaluate the relationship between the alpha 2-Heremans Schmidt glycoprotein (AHSG) gene polymorphism and endometriosis. DESIGN: Case-control study. SETTING: Department of Obstetrics and Gynecology, Seoul National University …
