Puberty begins when the Pituitary Gland secretes hormones into the bloodstream to affect the sex organs.

Explanation:

Puberty begins when the body releases the production of sex hormones. These hormones are inhibited in childhood, but are secreted in adolescence by the Pituitary gland. Thus, we can say that puberty begins when the pituitary gland secretes hormones in the bloodstream to affect the sexual organs.

The pituitary gland is an endocrine gland about 1 cm in diameter and 1 g in weight, located at the base of the brain, in an area called the phage saddle. It lies below the hypothalamus, which controls most of the pituitary functions, and is attached to it by the pituitary stem. It is also known as the "master gland" because it is responsible for the functioning of other glands in the body.
