Sperm quality differences between the rainy and dry seasons in captive black-handed spider monkeys (Ateles geoffroyi).
The present work provides an assessment of sperm measures (concentration, motility, viability, etc.) of three black-handed spider monkeys (Ateles geoffroyi) during the rainy and dry seasons in Mexico City, as well as an evaluation of the between-subjects variability of sperm quality. Twenty samples obtained by rectal electroejaculation and digested with trypsin were evaluated. The results showed that during the dry season (n = 9) the semen samples were of better quality than those obtained during the rainy season (n = 11). The individual animals showed differences in sperm concentration, although there were no differences in sperm quality.
