Mice belonging to the age three days post-partum to eight weeks were used. The histological observation of the testes up to six days post- partum in the present study showed that the semeniferous epithelium was made up of two distinct cell types’ viz., gonocytes and sertoli cells. At day eight postpartum, both Type A and Type B spermatogonia were observed on the basement membrane of seminiferous tubules. After ten days post-partum, primary spermatocytes were observed in two to four layers next to spermatogonial layer. Both the age groups showed the presence of Leydig cells and Sertoli cells. In addition to these cellular populations, testes of post-pubertal age groups showed secondary spermatocytes, round and elongated spermatids.en-USVeterinary ScienceVeterinary AnatomyArticle
