    ..5354, r = 0.6489, P < 0.01), respectively. The volume of the ovaries grew in proportion to the age of the females (P < 0.05). Puberty was the period of greatest uterine and ovarian growth. ..

    ..The aerobic bacterial population of the vaginal and preputial microbiota is similar in owl monkeys, and there are no differences in the number and bacterial species according to sex and social organization. ..

    ..We suggest that elevated neonatal DHEAS is possibly a residue from fetal adrenal secretion and that, as in humans, it might assist in neurobiological development. ..

    ..There was also a sex influence on blood urea nitrogen and creatinine levels. The results show that some hematological and clinical chemistry parameters in owl monkeys may be influenced by sex and age. ..

    ..Low DHEAS levels could be a marker of an unsuccessful pregnancy in primates. Monitoring fDHEAS levels can be useful in zoos and institute management and can be applied to wild and free-ranging populations. ..

    ..Our study indicates that castration can be adopted as a population control mechanism without drastically altering the social relationships of males. ..
