Why does the areola become larger and darker?

It has been believed since ancient times that women with dark nipples also have dark skin below. This kind of name is not wrong. The labia majora are not mucous membranes, they are covered by skin. Most women have pubic hair on their upper body, so it is not easy for men to notice, but the melanin will definitely settle. It is difficult to distinguish between Virgos and non-virgins. The pigmentation of the labia majora is mostly consistent with the range of male pubic hair.

Moreover, women who have had childbearing experience do not only have pigmentation when they have pubic hair, but the degree of pigmentation is also improved. Why the pigmentation of the labia majora is related to the color of the nipples and breast tissue, as well as the cause of discoloration, is still unclear. As far as the color of the nipple is concerned, the dark color may make it easier for the baby to distinguish. Only when the top of the breast is darker in color can the baby quickly find where the milk is.

When a woman becomes pregnant after insemination, as the fetus grows, the growth and development of mammary gland function is promoted and the breasts will enlarge. At the same time, the nipple will be larger for the baby to suck more conveniently, and the nipple or milk volume will also cause changes in pigmentation. The nipples do not darken due to pregnancy or childbirth, but are affected by the pigmentation of the labia majora, and the relationship between them is very clear. It is clear that it is not irrelevant, but it cannot be confirmed that pregnancy will cause the labia majora to turn black.

The nipples and labia majora become darker with age because the pigment deposition becomes more intense with age. Another saying that "women with rich sexual experience will have dark nipples, labia majora and labia minora" is actually incorrect.

Regarding the labia, there is data from a study of the genitals of 3,200 women by Professor Minoru Kasai of Shiga University, who is known as an authority on female genitals. Associate Professor Kasai said that sexual life experience has nothing to do with pigmentation. Although there are no studies on nipples, it seems impossible to say with certainty that frequent sexual intercourse will lead to darker nipples.

The color of the nipples, labia majora, and labia majora is determined by genetic factors. There is pigmentation on the scrotum of the male genitals, which also has genetic factors. Pigmentation sometimes occurs on the scrotum of newborn boys. Even if the nipples of a young woman who has no experience of pregnancy or childbirth turn black, it is rare. It is very rude to think that she has been "played too hard". The nipples of women who have passed menopause will quickly lose color due to changes in male hormones.
