Question

List the hormones secreted by the testis.

Answer 1

Hint:- The reproductive system in male is characterized by the presence of testis. The testis is found in males and it causes the production of male gonads or the sperm cells. In addition to the production of sperm cells, the testis is also related to the male developmental secondary characters.

Complete step-by-step solution:-
The gonads are the organs that are responsible for producing sex cells or the germ cells which are sperms in the males. In males, the important reproductive organ is the testis. The main function of testis is the production of male sex cells which are known as the sperm cells. The sperm cells are produced through a process of division to give rise to the mature sperm cells. In addition to the sperm production, the testis is also responsible for the production of specific hormones known as the androgens.
The principal androgen hormones secreted by the testis is known as the testosterone. It is produced by the Leydig cells that are situated in the spaces between the seminiferous tubules. The testosterone is a hormone of the steroid family. The production of testosterone is controlled by the anterior pituitary hormones such as luteinizing hormones. The testosterone is the prime sexual hormone present in males. It plays an important role in the development of male reproductive tissues such as in the testis and prostate. It also affects the growth of secondary sexual characteristics such as increase in body mass, increase in bone density as well as facial and body hairs.
The testosterone hormone is a steroid hormone containing a keto and hydroxyl groups at the position three and seventeen position respectively. It is biosynthesized in the liver to inactive metabolites. It is the hormone that promotes protein synthesis and enables growth of tissues with androgen receptors. The main effects of testosterone is the maturation of sex organs, and responsible for the male sexual drive. The regulation of the hormone testosterone is regulated by a negative feedback system and it involves release of the hormones from the hypothalamus as well as the gonadotropin from the anterior pituitary gland.

Note:- The hormones secreted by the gonads of the organism are known as androgens or androgen hormone. In male, testosterone is the main hormone secreted by the testis. It is a type of androgenic hormone. It is responsible for development of different sexual characteristic of male sex and also is responsible for the production and maturation of sperm cells. The secretion of testosterone is controlled by a negative feedback system from the anterior pituitary gland.
