A potential relationship between the acrosome response characteristics of bovine spermatozoa and their in vitro fertilizing ability

Original language description

The aim of the work was to study a potential relationship between acrosome response characteristics of bovine spermatozoa and their ability to fertilize oocytes and produce in vitro embryos. Sperm of artificial insemination bulls with a high rate (22.0 +/- 4.1%, group A, n = 7) or a low rate (10.3 +/- 4.1%, group B, n = 8) of embryos were used. For acrosome assessment, motile spermatozoa from a Percoll gradient were incubated with or without heparin and examined by the fix-vital sperm assay (FVSA). Thedifferences between the heparin-treated (H+) and the non-treated (H-) spermatozoa were significant (p < 0.01) in all bulls at all tested intervals. According to the kinetics of the heparin response, the bulls fell into three categories: fast (FR, n = 7),moderate (MR, n = 5) or slow (SR, n = 3) acrosome responses (p < 0.01). Five MR bulls were found in group A in comparison with two MR bulls in group B (57.1 Vs 12.5%; p < 0.05). Intensity of the acrosome response (response index) was sig
