Question

Which hormone controls spermatogenesis?

Answer 1

Hint: It is a gonadotropin and is a glycoprotein polypeptide hormone produced by the anterior pituitary gland of the body. It helps in the release of gonadotropic cells and takes part in various processes that include growth and development, reproductive processes, etc.

Complete answer:
Spermatogenesis is the process of formation of mature sperm s through a series of mitotic and meiotic divisions alongside metamorphic changes within the immature sperm cell. It is the male type of gametogenesis that brings about the formation of mature male gametes. The process of spermatogenesis is completed through the following three-phase; spermatocytogenesis, spermatogenesis, and spermiogenesis. The overall process of spermatogenesis occurs within the testes until the sperm moves to the epididymis and gains motility. Spermatogenesis forms millions of sperms every day. The primary spermatocyte is the starting cell during spermatogenesis.
The process of spermatogenesis is regulated by different glands and their products. The luteinizing hormone (LH) by the pituitary gland regulates the formation of sperm and therefore the production of testosterone within the male reproductive system. FSH functions as a stimulator for the maturation of primordial germ cells. In males, it induces the Sertoli cells found in seminiferous tubules to secrete androgen binding proteins (ABPs) that are regulated by the negative feedback mechanism of inhibition on the anterior pituitary. Specifically, the activation of Sertoli cells by Follicle Stimulating Hormone sustains spermatogenesis and also stimulates inhibin B secretion. - FSH also works with the Luteinizing Hormone (LH) in the reproductive system. GnRH or Gonadotropin-Releasing Hormone plays an important role in the FSH secretion, as it is shown that hypothalamic-pituitary disconnection leads to the cessation of FSH secretion.

Note:
The method of spermatogenesis is the basis for sexual reproduction which allows genetic recombination, leading to genetic variation among the species. Hormones controlling spermatogenesis vary among species. During the process of spermatogenesis, the male reproductive gametes are formed called the sperm cells. In humans, they are found in the seminiferous tubules of testes.
