Ovaprim induced effect on testis of Channa gachua

Abstract

The testis of Channa gachua, after administration of Ovaprim, showed changes in the morphology of testis and in the serum androgen level within period of 72 hrs. Morphological changes included spermatogonial proliferation, activation of leydig’s and sertoli cells, organization of seminiferous lobules and formation of lobular lumen in testis. Leydig cells were enlarged, exhibited characteristics of steroid producing cells. Sertoli cells became elongated, shown signs of high cellular activities and remained in close contact with spermatogonia. The lobular organization was achieved much earlier than the progression of spermatogenesis.
