kherson [118]

Answer:These are normal physiological processes that take place inorder to control and facilitate the development and maturation of the male sexual organs and characteristics.

Explanation: Male sexual development occurs between the ages of 10 and 14.

The anterior lobe of the pituitary gland secretes luteinising hormone which further stimulates the interstitial cells of the testes to increase the production of the hormone testosterone.

Under the influence of this hormone testosterone, sexual development and other characteristic changes take place.

The posterior lobe of the pituitary gland secretes growth hormone which helps in the growth of muscles and bones and a marked increase in height and weight.

The anterior lobe of the pituitary gland secretes testosterone which enlarges the larynx and deepens the voice.

Androgen and testosterone also produced by the anterior lobe of the pituitary gland causes growth of hair on the face ,axillae, chest, abdomen and pubis region.

From the anterior lobe of the pituitary gland, Dihydrotestosterone which has a high Androgenic action triggers the enlargement of the penis, scrotum and prostate gland.

The follicle stimulating hormone secreted by the adenohypophysis of the anterior lobe of the pituitary gland stimulates the maturation of the seminiferous tubules and production of spermatozoa.
