Spermatopoiesis

Spermatogenesis is the process of formation and development of male germ cells - sperm. It occurs in the male gonads - the testicles. Spermatogenesis begins during puberty and continues throughout a man’s life.

The process of spermatogenesis consists of several stages:

1. The formation of primary germ cells (gonadal embryos) in the embryonic period.
2. Migration of gonadal embryos into the testes.
3. Development of primary germ cells in spermatogonia.
4. Growth and maturation of spermatogonia into first-order spermatocytes.
5. Meiosis and the formation of second-order spermatocytes.
6. Spermatid formation.
7. Sperm formation and maturation.
8. Release of mature sperm from the testicles into the epididymis.
9. Transport of sperm into the vas deferens.
10. Release of mature sperm through ejaculation.

Spermatogenesis is regulated by hormones such as testosterone and FSH (follicle stimulating hormone). Impaired spermatogenesis can lead to infertility, so it is important to monitor the health of the male reproductive system.

Spermatopoiesis

The spermatopoet receives material for its body from the mother - the egg. One material is taken from the shell of the egg, and another from the nuclei and cytoplasm. Then it all gets mixed up. Diploid sperm is formed, 2n. Then, from the protogenic plasma, which is formed from two other materials, the spermatopothetes receive an egg or several - in polyspermy. And this is already supplemented by a mixture from one of the membranes or antipordations of estrucillary plasma. After this, everything is thoroughly mixed again.

That is why the number of spermatozoa can differ in different organisms, depending on the amount of material on which the spermatopoet can reproduce. There is also an alolet method of reproduction, there are the same advantages, but more reproduction occurs, spermatosides are simply separated from each other and one individual is obtained.
