Abstract
In the present study, the histoarchitecture of seminiferous epithelium of
testis in pre-pubertal and post-pubertal mice were observed. 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.
