  8. Spermatogenesis • With the on set of Puberty. • Three varieties of Male Primordial germ cells can be identified. • 1) Dark spermatogonium(Reserve Cells) • 2) Pale spermatogonium(Divide and give type A & Type B) • 3) Type B spermatogonium(Dark) • Divide and form few type B Cells. • Enlarge and become Primary Spermatocyte
