This prospective study investigated the relationship between anti-Müllerian hormone (AMH) level in the follicular fluid (FF) and the quality of the oocyte and embryo. A total of 65 FF samples from 54 women were included in this study. FF wa…

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…

Our aim was to investigate whether celecoxib, a cyclooxygenase 2 (COX-2) inhibitor, decreases the in vitro proliferation of leiomyoma cells if the inflammatory pathway is blocked. Menstruation is an inflammation of uterus that produces cyto…

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 …

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…

Mesenteric cysts are usually not considered in the differential diagnosis of pelvic cystic masses.The more common considerations for pelvic cystic masses include ovarian cysts such as, endometrioma, dermoid cyst, and other neoplasm.Here we …

Objective: The several strategies for unexplained thin endometrium are under debate. We evaluated the effect of concomitant administration of vaginal sildenafil and oral estrogen in women with a thin endometrium undergoing in vitro fertiliz…

ObjectiveTo evaluate the ovarian reserve changes after laparoscopic cystectomy, we prospectively evaluated pre- and postoperative serum anti-Müllerian hormone (AMH) level, and ovarian volumes.DesignProspective longitudinal study.SettingUniv…

ObjectiveTo investigate temporal and spatial relationships of vascular endothelial growth factor (VEGF)-A and its receptor (VEGFR-1) expression in a luteal endometrium obtained from patients with repeated IVF failure.DesignImmunohistochemic…

ObjectiveTo analyze the influence of postoperative GnRH agonist treatment on disease recurrence after conservative laparoscopic surgery for ovarian endometriomas according to duration of the treatment.DesignRetrospective cohort study.Settin…

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…

The aim of present study was to evaluate the relationship between endometriosis and polymorphisms in the endostatin and vascular endothelial growth factor (VEGF) genes, and their levels in serum in a Korean population. Serum endostatin leve…
