Secondary Sex Characteristics:These are physical signs of sexual maturation that do not directly involve sex organs. For example, breast development in females and deepening voice in males.
Adrenarche: This is the early stage of sexual maturation where adrenal glands start to release hormones called adrenal androgens.
