title: [Variability of seminal analysis and of objective parameters of sperm motility in semen during sperm capacitation in subjects with proved fertility].
abstract: We studied the variability of traditional semen analysis parameters as well as sperm motion characteristics analyzed by computer-assisted-semen analyzer in semen and after 2 hours of incubation in capacitation conditions. Twenty men with probed fertility provided three semen samples and 60 men provide one. The higher variability was observed with seminal sperm concentration, the lower variation was observed for percent motility and percent of normal morphology. Ten Oligospermic donors (12,5%) were observed in our population without other semen parameters abnormalities. Their motion characteristics were comparable to cells analyzed from normospermic men. A lower variability of sperm motion characteristics was observed during sperm capacitation compared to sperm movement in seminal plasma; suggesting that sperm motion characteristics during capacitation may be a usefull method additional to semen analysis to evaluate male fertility potential.
