This study aimed to analyze the effects of a new protocol with letrozole on the outcomes of in vitro fertilization (IVF) cycles in women with endometriosis. This retrospective cohort study was conducted for women diagnosed with endometriosi…

OBJECTIVE: This study aimed to determine whether the menstrual characteristics are different in Korean women with or without ovarian endometrioma. METHODS: We selected 95 premenopausal women aged below 39 years who underwent laparoscopic su…

OBJECTIVE: 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 included 124 women aged unde…

Interleukin-2 receptor b gene C627T polymorphism in Korean women with endometriosis: a case–control study

OBJECTIVE: Elevated serum progesterone (P) levels on triggering day have been known to affect the pregnancy rate of in vitro fertilization (IVF). This study aimed to identify the possible factors influencing serum P levels on triggering day…

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: To evaluate the association between the severity of endometriosis and the preoperative neutrophil-to-lymphocyte ratio (NLR) and serum level of cancer antigen 125 (CA 125). METHODS: Data were obtained from the medical records of 4…

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…

PURPOSE: To investigate whether preoperative serum anti-mullerian hormone (AMH) levels are lower in women with ovarian endometrioma and in women with mature cystic teratoma of the ovaries. MATERIALS AND METHODS: In a tertiary university hos…

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…

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 T…

PROBLEM: To investigate whether the glutathione-S-transferase P1 (GSTP1) exon 5 polymorphism is associated with susceptibility to advanced stage endometriosis in Korean women. METHOD OF STUDY: Case-control study in a collective of 260 pati…

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…

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…

BACKGROUND: CD163 is a hemoglobin scavenger receptor exclusively expressed in the monocyte-macrophage system and its soluble form (sCD163) has not yet been studied as a serum marker in women with endometriosis. The purpose of this study was…
