GENERAL HISTOLOGY

Detailed explanation-1: -Testosterone is the hormone that causes most of the changes in a guy’s body during puberty.

Detailed explanation-2: -For a male, the physical changes of puberty usually start with the testicles getting bigger. Dark, coarse, curly hair will sprout just above the penis and on the scrotum. The penis and testes will get larger, and erections happen more often. Ejaculation-the release of sperm-containing semen-also happens.

Detailed explanation-3: -The hypothalamus and pituitary gland control how much testosterone the testes produce and secrete. The hypothalamus sends a signal to the pituitary gland to release gonadotrophic substances (follicle stimulating hormone and luteinizing hormone). Luteinizing hormone (LH) stimulates testosterone production.

Detailed explanation-4: -The pituitary gland and the hypothalamus, located at the base of your brain, control the production of your male hormones and sperm. The hypothalamus makes gonadotropin-releasing hormone (GnRH), which controls the release of other hormones from your pituitary gland.
