PurposeTo 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) wo…

BackgroundThe oocyte retrieval is a critical step in assisted reproductive technologies, including in vitro fertilization and fertility preservation. Despite evolving techniques, the optimal aspiration pressure during retrieval remains deba…

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…

PurposeTo 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 methodsIn this observational study, 430 fresh IVF/ET …

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 surg…

ObjectiveGenetic 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 be…

PurposeTo 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 in…

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-b…

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 T…

BACKGROUND/AIMS: The aim of this study was to investigate the possibility that the K469E and G241R polymorphisms in the intercellular adhesion molecule-1 (ICAM-1) gene and the C-634G polymorphism in the interleukin (IL)-6 gene are associate…

ObjectiveTo investigate whether the transforming growth factor beta (TGF-beta) gene -509 C/T polymorphism is associated with susceptibility to advanced-stage endometriosis.DesignCase-control study.SettingUniversity department of obstetrics …

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…

BACKGROUND: The purpose of this study was to investigate the potential association of the C627T polymorphism in the interleukin-2 receptor beta gene (IL-2R beta) with the risk of endometriosis in Korean women. METHODS: Two hundred and thirt…

ObjectiveTo describe a case of suprapubic dermoid cyst that had been mistaken for cutaneous endometriosis.DesignCase report.SettingDepartment of Obstetrics and Gynecology, Seoul National University Hospital, Korea.Patient(s)A 22-year-old wo…

Objective: To explore the association of the interleukin-10 (IL-10) gene -592 promoter polymorphism with endometriosis in a Korean population. Methods: This study comprised 254 women with surgically or histologically diagnosed endometriosis…

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 explore the association of the CYP 1A1 gene polymorphism with the risk of endometriosis in a Korean population. Design: Case-control study Methods: Two-hundred fifty two Korean women with surgically or histologically diagnosed…

ObjectiveTo evaluate the relationship between the alpha 2-Heremans Schmidt glycoprotein (AHSG) gene polymorphism and endometriosis.DesignCase-control study.SettingDepartment of Obstetrics and Gynecology, Seoul National University Hospital, …
