Early and late puberty is associated with emotional and social difficulties. In fact, early puberty seems to be more challenging for <u>girls than boys</u>.
The pituitary gland produces hormones that leads to increase the synthesis of the sex hormones oestrogen and progesterone (in girls) or testosterone (in males), which causes the development of secondary sexual traits. This process is known as puberty.
In girls, menarche, or the first menstruation, usually occurs between the ages of 8 and 13 and marks the end of puberty. Puberty in boys typically starts between the ages of 9 and 14, commencing with the development of the sexual organs and ending with the development of facial hair and a deeper voice.
Early puberty may be particularly difficult for girls than boys, according to study. Early maturity in males has been associated with internalising symptoms like anxiety and externalising symptoms like tobacco use rather than full-blown problems. In girls, early puberty is linked to higher rates of eating disorders, disruptive behaviour disorders, drug use disorders, and depressive disorders in teenage girls.
