Abstract

OBJECTIVE: To study and compare raw and prepared semen samples from two consecutive days by conventional sperm parameters, various motility characteristics of spermatozoa determined by computer-aided sperm analysis and calcium ionophore-induced acrosome reaction. STUDY DESIGN: Semen samples of male partners in couples undergoing 81 cycles of double intrauterine insemination were studied. The first sample was produced after abstinence of 2-7 days and the second, 24 hours after the first. Both samples were processed by isolate sperm separation medium. RESULTS: Semen volume, sperm concentration and total motile spermatozoa were significantly reduced in day 2 raw and prepared samples, whereas normal morphology, motility characteristics and percentage of acrosome-reacted spermatozoa increased significantly in day 2 inseminated samples as compared to day 1. Oligospermic, asthenospermic and teratozoospermic samples showed asignificant improvement in concentration, various motility characteristicsand normal morphology of spermatozoa in day 2 samples as compared to day 1. CONCLUSION Men with normal samples showed improvements in normal morphology and acrosome-reacted spermatozoa, whereas those with subnormal semen samples from day 1 showed a significant improvement in concentration, various spermatozoal velocities and normal morphology on day 2.
