Sperm function and seminal oxidative stress as tools to identify sperm pathologies in infertile men

Routine semen analysis, which includes assessment of sperm motility, viability, and morphology, does not always provide complete diagnostic information as men demonstrating standard scores on these specific parameters sometimes remain infertile. In infertile men who had been subgrouped on the basis of sperm count, motility, morphology, and presence of leukocytes, an evaluation of sperm function and reactive oxygen species (ROS) was found to be effective tools to detect sperm pathologies.
