Description	The effect of D-penicillamine on the fertile life span of frozen-thawed bull spermatozoa was studied in Experiment 1. After thawing, the washed spermatozoa were incubated for 8 h in fertilization medium with 1 mg/mL polyvinyl alcohol (PVA) and 0.5 mg/mL D-penicillamine. The addition of cumulus-free oocytes together with 10% of bovine serum (BOS) + 4 IU/mL heparin to the 8-h incubated spermatozoa resulted in high fertilization and polyspermy rates (97/103, 94.2% and 49/97, 50.5%, respectively). When BOS was substituted with 3 mg/mL of BSA, the fertilization and polyspermy rates decreased to 33/91 (36.3%) and 3/33 (9.1%), respectively. The total absence of fertilization was observed after substitution of proteins with PVA. The 8-h sperm incubation in fertilization medium without D-penicillamine and following fertilization in medium + different capacitation supplements resulted in the total absence of or a very low fertilization rate. In Experiment 2, the first set of cumulus-oocyte complexes (COC) and c The effect of D-penicillamine on the fertile life span of frozen-thawed bull spermatozoa was studied in Experiment 1.
