Semen from 3 adult male capuchin monkeys (Cebus appella) was collected and evaluated, utilizing an electroejaculator and different collection media. In the first 24 samples collected, no liquid fraction was found. Procedures were then directed toward liquefying the entire coagulum by enzymes for semen evaluation. The enzyme system first utilized consisted of varying percentages of trypsin in 2.5% dextrose in half-strength lactated Ringer's solution. Because of high spermatozoan abnormalities using this mixture, a new enzyme solution was used. This solution consisted of 1% pronase in Eagle's medium, containing Earles' salts. At the end of the experiment, natural mating was allowed. The semen collected from the vagina revealed similar consistency, volume, and sperm concentration when compared with artificially collected samples. |
