We cannot a feminine nipple,the areola and the small lip of vulva color achievement judges whether has had the sex act basis,this kind of judgment is very unscientific. As long as the feminine female hormone level compares Gao Zhe,can appear the nipple,the areola and the small lip of vulva color becomes dark,this is one kind of healthy feminine sexual character. After menopause woman,because the female hormone level is low,nipple,the areola and the small lip of vulva then can appear the pink,then you can say she is the maiden?
Thought since old times,the nipple becomes dark female,following color also is black. This view not wrong. The big lip of vulva is not the mucous membrane,but has the skin to cover. Above overwhelming majority female all steadily pubic hair,therefore the male not easy to detect,but the pigment can certainly precipitate. Does not divide the maiden or the non-maiden,big lip of vulva pigment precipitation,mostly and is long the pubic hair the scope is consistent. Moreover has the birth experience female,is not restricted in the long pubic hair time only then has the pigment precipitation,the precipitation degree also improves. Why does the big lip of vulva pigment precipitate with the nipple,young quantity color related,as well as the color deterioration reason still did not know at present. The list speaking of the nipple color,therefore the color deep possibly is causes the baby easy identification. Only then the Breast acme color is deep,the baby can find milk whereabouts very quickly.
After the feminine fertilization is pregnant when,grows along with the embryo,promotion mammary gland function growth,the breast can increase. But simultaneously the nipple also can facilitate the suction huge for the baby,the nipple or the young quantity also can cause the change which the pigment precipitates. The nipple is not because of is pregnant or the production becomes dark,but and big lip of vulva pigment precipitation influence,relations in which is extremely clear. May determine is,certainly not irrelevant,but cannot determine becomes pregnant when can cause the big lip of vulva to become dark.
The nipple and the big lip of vulva grow along with the age become dark,is because of along with the age,the melanin precipitation can be intense. Is named the " sexual intercourse experienced female,nipple or big lip of vulva,the small lip of vulva color can black ",actually this is wrong. About small lip of vulva,has well-known incites by the feminine sex organs authority celebrates university associate professor the coolie hat well solid department to investigate 3200 feminine sex organs the materials. Coolie hat well associate professor said,the sexual intercourse experience and the pigment precipitate relate. Although not about nipple investigation,as if cannot affirmative say the sexual intercourse number of times multi-colors can be black.
Decides the nipple or the big lip of vulva,the small lip of vulva primary color inherits the factor. Has the pigment precipitation in the masculine sex organs scrotum,also has the heredity factor. Just was being born sometimes the baby boy scrotum also could appear the pigment precipitation. Has not been pregnant,even if the birth experience young feminine nipple becomes dark,also is born that way,if thought she has been played by " ",that is a matter which begs pardon very much. Feminine " menopause " nipple,the areola can change color rapidly,that is because of the hormone change result.
Therefore treats also is the immaterial matter.
