Are there pink nipples?

Every girl needs to go through puberty. She has just started to develop physically and has not yet experienced childbirth and breastfeeding, so her breast nipples are pink and not very dark, and there is no local pigmentation. Pink nipples are generally only found in young girls and unmarried girls, but some people have black nipples. This is because after marriage, coupled with breastfeeding and childbirth, the nipples undergo physiological changes. Let me introduce you to some knowledge about nipples.

The depth of color is related to a person's physique, and not everyone is pink. As people grow and mature, their skin color will deepen. This is mainly regulated and controlled by the secretion of certain hormones in the body. The depth of color and the person's physical condition

Shape structure

Female nipples

The diameter of the cylindrical part is generally 0.8~1.5cm, and it is about 1.5-2cm above the areola plane. Normal nipples are symmetrical on both sides and have a pink or brown surface.

The surface around the nipple is uneven and a bit like cauliflower. Female nipples have 6-9 mammary gland openings for delivering milk and varying numbers of sebaceous gland openings.

There are usually no more than 20 sebaceous gland openings. The nipple consists of the nipple top, nipple neck and nipple base. The nipple neck is affected by age and the physiology of childbirth and breastfeeding. Generally, the nipple neck of young girls is short, small at the top and large at the bottom, a bit like a cone. After childbirth and breastfeeding, the nipple neck becomes larger and longer, making it easier to breastfeed. At the same time, after pregnancy, due to the increase of estrogen and progesterone in the body, the color of the nipples gradually darkens.

Male nipples

The male nipple is located in the fourth intercostal space. The male areola is a round, pigmented skin with a diameter of 15 to 35 mm, sometimes longitudinally oval. There are a small amount of hair and glands in the areola, including sweat glands, sebaceous glands and mammary glands. The nipple can be roughly viewed as being cylindrical or cone-shaped. Its shape varies greatly. In normal shape, the nipple is 0.5 to 1 cm above the areola plane.

Under normal circumstances, male nipples are shaped like hemispheres, and the areola and nipples are colored. When stimulated, the smooth muscles inside them will reflexively contract, causing the areola to shrink and the nipples to stand up. The nipples are relatively short. Moreover, the mammary ducts have degenerated and have no lactation or other functions, but they are also sexually sensitive areas. Most of them are black in color and have hair.

Developmental process

Before puberty, girls' nipples will bulge out separately. After this, the nipple and breast develop into a small hillock. As the breasts grow larger, the nipple and areola become more prominent and enlarged within the breast outline.

When nipples reach the mature stage, most people's nipples protrude outward. The nipples of unmarried women and women without children are relatively small. Only after pregnancy, when the breasts and nipples are affected by the estrogen and progesterone in the pregnant woman's body, the mammary alveoli and mammary ducts proliferate, do the nipples gradually increase in size and become more protruding, preparing for feeding the child. A normal nipple is a cylindrical protrusion with a hole, about 1 cm in diameter, about 1.5-2 cm in height, and dark in color.

Functional purpose

Both men and women have nipples, and in the early days, the functions of nipples in both men and women were the same. However, with continuous evolution, male nipples have degenerated so that their purpose is relatively single - to provide overall aesthetic appearance. In addition to shouldering the important responsibility of nurturing the next generation, female nipples also serve as embellishment.
