Zoology - Human Reproduction Question with Solution | TestHub

Testes are male gonads. These are present outside the abdominal cavity. The transverse section of the testes shows many lobules and each lobule consist of 1-3 seminiferous tubules. These tubules show the presence of two types of cells. Spermatogonia i.e. mother cells and Sertoli cells i.e. nurse cells that are present in between the spermatogonia. Spermatogonia form sperms while Sertoli cells nourish the sperms. In between the seminiferous tubules, there are present Leydig cells or interstitial cells that secrete male sex hormone testosterone.
