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. Am. J. Primatol. 57:35–41, 2002. © 2002 Wiley‐Liss, Inc.
