Although usually a capacitating substance such as heparin is used during sheep in vitro fertilization, evidences suggest that the cryopreservation process and Percoll technique could induce spontaneous capacitation. This study aimed to compare ovine, caprine and bovine frozen-thawed sperm after mini-Percoll processing on sperm parameters, receiving or not heparin supplementation. In conclusion, frozen-thawed ovine, caprine and bovine spermatozoa processed with mini-Percoll behave similarly regarding to capacitation status and does not require heparin supplementation during in vitro incubation to achieve capacitation.
