| Abstract: | OBJECTIVES: To assess the concentration of Plasma Glutathione Peroxidase (plGPx) in the peritoneal fluid (PF) of patients with unexplained infertility and infertile women with minimal and mild endometriosis. MATERIALS AND METHODS: 33 women were studied, including 8 infertile women with minimal or mild endometriosis, 15 patients with unexplained infertility and 10 patients with tubal occlusion (a reference group). Concentration of plGPx was measured in the PF using a commercially available ELISA kit (Oxis Inc.). RESULTS: The plGPx concentration was significantly (p = 0.04) lower in PF from women with unexplained infertility (846 +/- 177 ng/ml) compared to the reference group (1023 +/- 238 ng/ml), but did not differ significantly (p = 0.25) between women with endometriosis (918 +/- 81 ng/ml) and patients with tubal infertility. CONCLUSIONS: Our results suggest that low peritoneal plGPx concentration may play a role in the pathogenesis of infertility. |
