How is 14 years old did not come menstruation to have pubic hair to return a responsibility

Puberty is the development period of secondary sexual characteristics, mainly the development of sexual organs and menstruation. The development of pubic hair is often earlier than menstruation. Menstruation usually comes at the age of 12-14, and pubic hair begins to grow at the age of 9 at the earliest.

After women enter puberty, the ovaries gradually mature and begin to secrete female hormones, and then the endometrium changes to produce menstruation. When the endometrium falls off, menstruation will be formed. Girls usually have their first menstruation around the age of 12, but also at the age of 17. This is related to body specificity.

As the secondary sexual characteristics gradually mature, in order to protect themselves, pubic hair begins to grow. In addition to sexual characteristics, pubic hair can also reduce the friction and pain caused by rapid movement during sexual behavior, and can also play the role of "ventilation".
