The objective was to evaluate the effect of adding different concentrations of cholesterol carried by cyclodextrin (CCC) on frozen ovine sperm. Two ejaculates were collected from 10 rams (n=20) and diluted in Tris-Yolk until the final concentration of 200 x106sptz/mL was reached and kept in a water bath at 32 °C. The CCC was added: control (0,0mg), 1.5mg, 3.0mg, and 6.0mg of CCC/120 x106sptz/mL. After the addition, the semen was cooled at 5 °C for two hours, after that period, filled in 0.5mL straws, and then conditioned under liquid nitrogen vapor (N2L), at 8 cm of the liquid/15 minutes, and then immersed in N2L. The samples were analyzed for sperm motility, plasma membrane and acrosomal membrane integrity, mitochondrial activity, and bind...
