In spermatogenesis, a diploid spermatogonium is changed into four haploid spermatids. The spermatogonia are found as juvenile germ cells discovered close to the dividers of each seminiferous tubules. Mitosis is engaged with the augmentation of these cells. Each one spermatogonium is 2n and comprises twofold number chromosomes (46) (Jones and Lopez, 2006).
