Abstract

Observations were made on four captive breeding groups of rhesus monkeys in order to measure hormonal, behavioral, and genital changes in adolescent males during the annual mating season. Three questions were addressed with regard to possible effects of social environment upon reproductive maturation: (1) Does male agonistic rank influence adolescent development? (2) Does affiliation between adolescent males and adult females during the mating season influence the males' reproductive development? (3) Does maternal rank exert any effect upon reproductivematuration in adolescent sons? In many (but not all) cases male rank was positively correlated with circulating testosterone and testes weights during the mating season. Affiliative behavior (allogrooming and sexual interactions) between adolescents and adult females in their social groups bore no relationship to the degree of reproductive maturation in males. Mounts involving intromission were infrequent, but sons of high-ranking mothers gained significantly more intromissions than sons of lower-ranking females. Maternal rank was also found to correlate with circulating testosterone levels, testes weights, growth of the baculum (os penis), and maintenance of body weight in adolescent sons during the mating season. By contrast, levels of P-endorphin in the cerebrospinal fluid of adolescent males did not correlate with social rank, testosterone levels, or genital development. These findings point to possible effects of maternal rank, as well as intermale agonistic rank, in determining reproductive maturation during adolescence in the male rhesus monkey.
