Abstract: This study aimed to characterize the gonadal postnatal development in rabbits from white population found in Algeria. 122 rabbits aged between 4 and 20 weeks were sacrificed, gonads were weighed and fixed for histological and morphometric investigation. The macroscopic parameters including body weight, testicular weight and volume were measured, as well as the parameters of the microscopic testicular seminiferous tubule. The comparison between the different variables showed an increase in live weight and gonadal depending on age. The obtained data were subjected to analysis of variance using the Origin 7.5 software pro. Histological study showed the onset of 1 to 12 weeks spermatocytes, and smoothed and elongated spermatids at 16 weeks, while the first sperms were visible at 20 weeks. All histological findings recommended a rabbit reproduction implementation for the studied population from 20 weeks.
