The epithelium consists of Sertoli's sustentacular cells and the spermatogenic cells. The Sertoli's cells form a single-layered lamina and extend from the basal lamina to the tubule lumen. With their labyrinthine cellular processes they surround the individual types of germ cells more or less completely. Spermatogenesis is thus accomplished in close contact with the Sertoli's cells, which not only have supportive and nourishing functions, but also secrete hormones and phagocytize cell fragments. Somewhat above the basal lamina they are bound to each other through complicated occluding junctional complexes (tight junctions), so that 2 separated compartments are present in the epithelium: a basal one, in which the spermatogonia are lined up, and a luminal one, in which all the other stages of spermatogenesis are found.

2... Generally when a male is entering in youth stage i.e. 15 to 18 years but full sperm structure develops after 21 years only
3... The male should be complete mature mentally i.e. when he can take right decision at what ever age may be he should give birth to the child.
4... They should follow healthy habits to form healthy sperm
5... Their mind should be mature before taking the decision to healthy child with super qualities.
