Abstract: In this experiment, the discrepancy was compared among the “Swim-up” , Induction by A23187, Percoll and Incubation after Percoll methods for ovine sperm capacitation in vitro with chlortetracycline fluorescence (CTC) staining and in vitro fertilization. The results showed that the rates of sperm capacitation and the cleavage treated by Swim-up method were higher than the others. It might be suggested that the Swim-up method is exactly suitable for the application of in vitro fertilization of sheep. 
