[Mechanism of the dysfunction of the bull spermatozoa treated with cadmium].

Objective: Heavy metals such as cadmium (Cd) are widely distributed in the environment as industrial pollutants and characterized by their ability to affect the male reproductive system. The objective of the present study was to test the effect of Cd in the concentration range from 10 to 1000 micromol/L, in vitro, on the membrane and DNA integrity, motility, and ability of sperm to undergo acrosomal exocytosis in Holstein bull spermatozoa.

Methods: Bull semen samples were processed for sperm analyses using semen-diluting fluid, PBS.
