Selectivity of porcine zona pellucida to bind spermatozoa with normal chromatin structure

Abstract

This study aimed to investigate the selective ability of swine zona pellucida (ZP) to bind spermatozoa with normal nuclear chromatin. Ten ejaculates of four boars were used, while hemizona assay was applied for evaluation of binding capability. The results of this study showed that swine ZP has the ability to select spermatozoa with normal chromatin structure for sperm-zona binding process.
