Um total de 12 touros da raça Guzerá, de 24 a 34 meses de idade, avaliados andrologicamente, foram submetidos a teste da libido com o objetivo de estudar o comportamento sexual em curral, por cinco, 10 e 15 minutos de observação; e associar com características andrológicas (aspectos físicos: motilidade, vigor, turbilhonamento e concentração espermáticos, e volume do sêmen; e morfológicos: defeitos espermáticos maiores, menores e totais, do sêmen), circunferência escrotal (CE), classificação andrológica por pontos (CAP), peso corporal, idade e concentrações séricas de testosterona. Observou-se, de forma geral, baixa resposta dos animais aos testes, uma vez que menos da metade dos animais foi classificada com libido média ou alta. Verificou-se pequena variação na pontuação entre os tempos de observação, com escore 3,0 em cinco minutos e 3,3 em 15 minutos de avaliação (p>0,05).
