Reproductive engineering encompasses a range of advanced tissue engineering techniques aimed at addressing infertility that is non-curable with current assisted reproductive technology (ART). The use of animal models has been crucial for th…

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…

Although advances in cancer treatment and early diagnosis have significantly improved cancer survival rates, cancer therapies can cause serious side effects, including ovarian failure and infertility, in women of reproductive age. Infertili…

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…

Nonhuman primates (NHPs) have been widely used in reproductive biology, neuroscience, and drug development since a number of primate species are phylogenetically close to humans. In this review, we summarize the use of NHPs for nonclinical …

OBJECTIVE: To investigate the influence of laparoscopic surgery on the natural conception rate in infertile women with endometriosis during the first year after the operation. METHODS: We retrospectively studied 43 infertile women with sur…

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…

OBJECTIVE: There are limited data regarding the significance of elevated serum CA-125 level during IUI cycles, even though it is used widely during the initial evaluation of infertile patients. The aim of this study was to investigate the p…

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 …

OBJECTIVE: To describe a case of suprapubic dermoid cyst that had been mistaken for cutaneous endometriosis. DESIGN: Case report. SETTING: Department of Obstetrics and Gynecology, Seoul National University Hospital, Korea. PATIENT(S): A …

This study was performed to investigate the association between FSH receptor (FSHR) gene polymorphism at position 680 and the outcomes of controlled ovarian hyperstimulation (COH) for in vitro fertilization and embryo transfer (IVF-ET) in K…

The aim of the present study was to evaluate the clinical efficacy of half-dose (50 mug) and further reduced dose (33 or 25 mug) gonadotropin-releasing hormone agonist (GnRH-a; triptorelin) long protocols for multifollicular ovarian stimula…

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 …
