Captive adult male jaguars (Panthera onca) from two locations in southeast Brazil were studied to evaluate the effects of season on endocrine and testicular function. For assessment of testicular steroidogenic activity, androgen metabolite concentrations were measured in fecal samples collected one to three times per week over 14 ( n=14 ), 9 ( n=1 ) or 7 months ( n=1 ). To assess seasonality, d...
