Abstract

This paper study aims to compare morphologically and histologically the testes of the two predatory animals (mongoose and genet) with the two pets (cat and dog). The research is based on direct observations, preparation of histological sections, and accurate measurement of the seminiferous tubule diameters and epididymal ducts. For this purpose, the testes and epididymis have been removed and quickly fixed. The results of the histological comparison showed that the size is more pronounced in dogs than in other species; significant differences were found between wild and domestic species. This study requires further investigation regarding the great differences between selective breeding and implies the possibilities of using biotechnologies, such as artificial insemination, to increase their multiplication especially that of those exposed to extinction.
