小阴唇大约有多长 正常尺寸又是多少

The labia are an important part of the female external genitalia. Divided into labia majora and labia minora. The labia majora: These are located on the sides of the female vulva and may also have hair. The labia minora: are two soft, darker skin located on the inside of the labia majora and outside the vaginal opening.

How long is the labia minora

Let's talk about the labia minora on the left first, which has an average width of 2.1 cm (between 0.4 and 6.4 cm) and an average length of 4 cm (between 1.2 and 7.5 cm). The labia minora on the right had an average width of 1.9 cm (between 0.3 and 7.0 cm) and an average length of 3.8 cm (between 0.8 and 8.0 cm).

So statistically speaking, the labia minora on the left is larger than the labia on the right. Of course, this is just a statistical data, not everyone. At the same time, we will also find that the size of the labia minora varies greatly from person to person. Taking the left labia minora as an example, the width varies from 0.4 to 6.0 cm.

At the same time, the length of the labia minora also decreases with age.

The role of the labia minora

The labia minora are soft, without subcutaneous fat, rich in sebaceous glands and sweat glands, and the surface is moist, smooth and hairless. Submucosal nerve distribution is rich, so the feeling is very keen.

The labia minora are thin, and their size and shape vary greatly from person to person. Some are not symmetrical, one side is big and the other is small, this is normal.

In unmarried and married women with last childbirth, the labia minora are closed and play a role in protecting the vagina and internal genitalia, which is part of the natural defense function of women.

The front of the labia minora merges with each other and is divided into two lobes, the anterior lobe surrounds the clitoris to form the clitoral foreskin, and the posterior lobe forms the clitoral frenulum. The posterior end of the labia minora merges with the posterior end of the labia majora, forming a fold in the midline, which is the labia frenulum, which is easy to tear during childbirth.

The labia minora is located on the inner side of the labia majora, and is also a skin fold. There is no pubic hair growth on it. There are blood vessels, elastic fibers and a small amount of smooth muscle under the skin, and there are rich nerve distribution, and the feeling is very sharp. There are great individual differences in the shape and size of the labia minora. Some people's labia minora are very narrow, and some people's labia minora are very long and hang down to the outside of the labia majora. Some are very thick, some are very thin, some are irregular umbrella-shaped; some are as large as fingernails, with a typical semicircular shape. Some people are pale red; some are brown-red; some people even have two colors of labia minora, the outer side is brown-black, and the inner side is pink. In general, its color deepens with age and number of deliveries. Some African tribal women are proud of the length of their labia minora, so they pull it from childhood, so the labia minora in adulthood are thick and long, protruding high beyond the labia majora, but their size has no obvious effect on sexual response .
