Abstract

Biometric data of the testicular and corporal weight development of 31 Agoutis (Dasyprocta aguti), from the birth up to 14 months of age, were analyzed. The correlations between corporal weight, age and testicular parameters were highly significant. Testicular weight, testicular volume, as well other testicular biometric parameters (length, diameter and perimeter), evolved slow and gradually until eight months of age. Beginning on 9 months of age, the growth was faster, and in this period. the seminiferous epithelium was already formed. Biometric development of the testes can be shared in two phases: 0 - 8 months and 9 - 14 months of age, however the 9 months age are the maximum point of the testicular development in Agoutis (Dasyprocta aguti) rised in captivity.
