Question

explain in detail the formation and maturation of sperms.​

Answer 1

Answer:

Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. ... Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa and four haploid cells.

Answer 2

Hello !!!

The process of formation of sperms is called Spermatogenesis.

It occurs in male gonads testis. Testis is made up of many seminiferous tubules lined by germinal epithelium.

Cells of this layer divide to form spermatozoa in the following ways :

MULTIPLICATION PHASE :

• At maturity the primordial germ cells divide by mitosis to produce a large number of spermatogonia .
• TYPE A spermatogonia is in the Stem cells which divide to form spermatogonia.
• TYPE B spermatogonia are the precursors of sperms.

GROWTH PHASE :

• Type B spermatogonium actively grows to a primary spermatocyte.
• It obtains nourishment from Nursing cells.

MATURATION PHASE :

• Each primary spermatocyte undergoes two maturation divisions.
• The first maturation division is REDUCTIONAL and forms two haploid daughter cells called SECONDARY SPERMATOCYTE.
• Both spermatocytes then undergo second maturation division to form four haploid spermatids.

SPERMIOGENESIS :

• It is the process of transformation of spermatic to a spermatozoan.
• The spermatozoans are then known as SPERMS.
• The four spermatids becomes the head of the sperm
• The golgi apparatus, containing proteolytic enzymes , becomes the acrosomal cap.
