Multiplication phase

Multiplication Phase: During sexual maturity, the division of undistinguishable primordial germ cells occurs several times due to mitosis. This is majorly to produce a large count of spermatogonia. These are of two kinds: type A and type B. Type A spermatogonia act as the stem cells that divide to create additional spermatogonia. On the other hand, Type В spermatogonia can be thought as the prototypes of male *** cells.

Creation of Spermatids

This procedure covers three stages; namely:

• Multiplication Phase: During sexual maturity, the division of undistinguishable primordial germ cells occurs several times due to mitosis. This is majorly to produce a large count of spermatogonia. These are of two kinds: type A and type B. Type A spermatogonia act as the stem cells that divide to create additional spermatogonia. On the other hand, Type В spermatogonia can be thought as the prototypes of male *** cells.
• Growth Phase: Do remember that, every type В spermatogonium dynamically grows to form a superior primary spermatocyte through nourishment received from the nursing cells. This phase further concludes in the maturation stage.
• Maturation Phase: Under this, primary spermatocyte experiences two successive divi­sions. These are termed as maturation divisions, and meiotic is the first maturation disunion. Therefore, the primary spermatocyte segregates into two haploid daughter cells known as secondary spermatocytes. Further, both the secondary spermatocytes suffer second maturation separation that is a regular mitotic division. It leads to the creation of four haploid spermatids.
