Abstract

The conditions for stimulation of in vitro capacitation and the acrosome reaction of ejaculated buffalo sperm has been determined. Washed ejaculated sperm were successfully capacitated in BWW medium supplemented with bovine serum albumin (BSA) and a sperm motility factor(s) (SMF(s) isolated from the adrenal glands of rats. The acrosome reaction was induced in capacitated sperm by introducing Ca++ ions (final concentration 5 mM) into the medium. Supplementation of BWW medium with SMF(s) in the presence of BSA significantly increased the percentage of sperm showing capacitation and the acrosome reaction. SMF(s) also significantly increased the percentage motility, the percentage forward motility and maintained a higher percentage of live sperm in BWW medium under the conditions used in this study. The significance of the present findings is discussed.
