REACTIVE OXYGEN SPECIES IN HUMAN SEMEN IN RELATION

Popis výsledku v původním jazyce

Aims: Excessive production of reactive oxygen species (ROS) in semen has been linked to male infertility. Main sources of ROS in male genital tract are immature and/or damaged spermatozoa and a subpopulation of leukocytes known as polymorphonuclear neutrophils (PMN). Methods: Study group included male partners of infertile couples, 67 normospermic males (group B) and 98 males with sperm abnormalities in one or more parameters (group C), 36 fertile volunteers (group A) served as controls. Sperm parameters were determined according to WHO guidelines. The ROS production was measured by chemiluminiscence in sperm suspension in phosphate buffered saline. Results: All fertile volunteers in the control group had seminal PMN concentrations below 0.5x106/ml. Therefore study subjects, 67 normospermic and 98 men with sperm abnormalities, were further subdivided into two subgroups of PMN concentrations: (1) < 0.5x106/ml and (2) 0.5 to 1.0x106/ml. The ROS production in individuals varied greatly fr
