1. Development of pubic hair:

Breast development can start as early as 8 years old, with an average of 10-11 years old. Most children begin to develop before the age of 13. Pubic hair develops and begins to appear before the breasts mature. The pubic hair forms an angle of no more than 30 degrees with the skin surface, covering the midline downward from the mons pubis and labia majora, forming an inverted triangle with a horizontal upper edge.

The amount, distribution, and color of pubic hair vary greatly from person to person. Female pubic hair can also extend from the mons pubis downwards and form strips together with the pubic hair on the labia majora. When the breasts are fully developed and stand high on the chest; pubic hair grows, the mons pubis becomes thick, the pelvis becomes wide and flat, the buttocks become enlarged, the muscles and fat are smoothly distributed, and the curvaceous female body shape is formed, and the female puberty is completed.

Therefore, by the age of 18, a woman's secondary sexual characteristics have all matured, that is, when a girl reaches the age of 18, her sexual organs and sexual functions have all matured and she has the ability to reproduce.
