Introduction to the female development process

As we all know, secondary sexual characteristics begin to appear when people enter puberty. Girls generally develop it earlier than boys. Europeans develop earlier and faster than Asians, and blacks also develop earlier and faster. This may be due to long-term residence in frigid and tropical zones. . Chinese girls generally begin puberty at the age of 11 or 12, while boys generally begin to develop at the age of 13 or 14. The following is an introduction to the development process of women.

1. Under normal conditions, growth signs will begin to appear after the age of ten. Between the ages of ten and eleven, girls' height and weight will grow rapidly. So at this time girls often outnumber boys. By this time, the breasts have already changed. The nipples will be slightly raised. The nipples will change color slightly and pubic hair will begin to grow.

2. I would also like to point out that some girls may still have flat breasts when they are 20 years old. Some people don't even have a few pubic hairs in their entire life. This is possible, but it is not necessarily the result of poor development. Most of the time, it is just because of genetic, nutritional and other factors that the child develops differently from others.

3.9 to 10 years old: Sexual development starts, and the first part to be affected is the pelvis. We found that the pelvis begins to widen gradually during this period. Next comes the chest, where one or both nipples slowly swell up like buds.

10 to 11 years old: The breasts gradually swell like hillocks. If you touch them carefully, you can feel a slightly hard lump. At the same time, the areola area expands, indicating that the mammary glands begin to develop.

4.11-12 years old: A small amount of short and fine hair begins to sprout on the pubic area, but it is not real pubic hair yet.

12-13 years old: Stimulated by estrogen secreted by the ovaries, the breasts grow significantly faster and you may feel slight pain. But don't be nervous, this is a physiological phenomenon during the development process. Once the mammary gland matures, the pain will naturally disappear.

5.13-14 years old: Most girls have their first menstruation, which is called menarche (some may be as early as 11-12 years old, and some may be as late as 18-19 years old). Menarche is one of the important signs of puberty. At menarche, ovarian function is still unstable, so the menstrual cycle is often irregular. Later, as the body develops, the menstrual period will naturally become regular. Ovulation usually occurs in the second year after menarche, when the menstrual cycle becomes normal, and ovulation may occur in every cycle. At the same time, armpit hair begins to grow on both sides of the armpits.

14 to 15 years old: The pelvis widens further and the menstrual cycle begins to form. If the menstrual cycle lasts for more than six months, or if a period lasts for more than 11 days, it is abnormal and you should seek medical help. Real pubic hair begins to replace downy hair. The growth of pubic hair goes through four stages: sparse and light-colored, gradually darkening, becoming thicker and curly, and changing from a small distribution to a dense distribution, before reaching the pubic hair distribution state of an adult female.

The above introduces the development process of women. Every stage of life requires special attention. Women should pay attention to supplementing the nutrients needed by the body during the development process, eat more fresh vegetables and fruits, exercise appropriately, and keep a comfortable and happy mood. I hope every woman has a beautiful adolescence.
