Artificial insemination using sexing semen is expected to produce calves with the desired sex. One sexing sperm method is the percoll density gradient centrifugation method. This study aimed to determine the changes and the relationship between motility and acrosome reaction after sexing process using percoll density gradient centrifugation. The material used was semen of ±5 years old Ongole crossbred bull with a bodyweight of ±700 kg as many as three bulls with mass motility 2+ and individual motility 70%. The method used was to compare fresh semen with sexed semen after the cooling process. Parameters measured were motility characters using CASA analysis, which included motility parameters, progressive motility, capacitation, and no acrosome reaction. Statistical analysis used paired T-test to distinguish among fresh semen, after sexing and cooling process. In comparison, regression and correlation were used to analyze the relationship of capacitation and hyperactivation sperm with no acrosomal reaction with motility and progressive motility. The results showed that motility and progressive motility decreased after the sexing and cooling process. Meanwhile, the acrosomal reaction, capacitation, and hyperactivity increased.
