RESUMEN
We aimed to evaluate the effect of supplementation of ACP-118® extender with the antioxidant catalase (10 and 50 µg/ml) on Sapajus apella sperm motility, vigour, and plasma membrane integrity during the processes of seminal liquefaction, cooling, and freezing. Catalase did not affect any of the evaluated parameters after semen dilution or cooling. Cryopreserved sperm in the presence of 50 µg/ml catalase presented a plasma membrane integrity similar to that fresh sperm, however.

BACKGROUND: Ovarian absence is a rare condition with congenital or traumatic origin. METHODS: Gross and microscopic examination of two capuchin monkeys were performed. RESULTS: Case 1 had absence of the right ovary and distal uterine tube, bilateral absence of fimbriae, and a rudimentary uterus. Case 2 had unilateral ovarian absence, but a functional contralateral ovary, and a normal uterus. CONCLUSIONS: Unilateral ovarian absence was confirmed in two capuchin monkeys for the first time.
