Physiological effect
Absorbs sweat and mucus
Pubic hair is not useless, but grows to protect our body. Pubic hair can absorb the sweat and mucus secreted by these parts and spread to the surrounding area, which is beneficial to our health. During sex, it can also play a role in increasing the pleasure caused by friction in the external genitalia. In addition, pubic hair also has the function of keeping warm and protects the normal survival temperature of sperm and eggs.
Reduce friction and pain
In addition to being a sexual feature, pubic hair can also reduce friction and pain caused by rapid movement during sexual activity. In addition, the human pubic sweat glands are relatively thick and rich, sweating a lot, and the hidden parts are prone to poor ventilation, pubic hair. The existence of it can play the role of "ventilation".
menstrual cycle
General introduction
Pubic hair is one of the secondary sexual characteristics of the human body. Pubic hair begins to appear at the age of 11-12 for girls and 12-15 for boys. If there is no pubic hair or sparse pubic hair at this time, it is medically called hirsutism. A woman suffering from hirsutism is commonly known as "white tiger", and men's chest hair, belly button hair and pubic hair are connected into a line called "green dragon". is nonsense. It puts a lot of pressure on the patient's spirit, and some people even dare not fall in love.
puberty
Generally speaking, after the onset of puberty, adolescents, due to the action of estrogen and androgen, make their pubic hair follicles grow pubic hair. Androgens in men are secreted by the testes, and there is also a certain amount of estrogens in women, which are secreted by the adrenal cortex and ovarian stroma. Whether male or female, the presence and density of pubic hair is related to the level of estrogen and androgen in the body and the sensitivity of pubic hair follicles to estrogen and androgen. Those who simply do not grow pubic hair and are otherwise normal may be caused by the insensitivity of pubic hair follicles to their own estrogen and androgen. This is not pathological and has nothing to do with it. It does not affect physical health, marriage and fertility, so there is no need to worry about it. Anxiety, let alone believe those nonsense.
disease problem
Of course, very few people can also be caused by diseases, such as hypothyroidism, and pubic hair may be sparse. Another example is inflammation, tumor or trauma that damages the function of the structure of the hypothalamus-pituitary-adrenal axis, which affects the secretion of sex hormones. Or due to congenital diseases or some unexplained diseases, such as idiopathic Addison's disease, which affects the secretion of sex hormones, manifested as menstrual disorders, amenorrhea, sparse pubic hair, and sexual dysfunction. Another example is the influence of drugs, the long-term use of glucocorticoids in large quantities before puberty, feedback inhibits the function of the hypothalamus-pituitary-adrenal axis, resulting in hypofunction or even atrophy of the renal cortex, and the secretion of estrogen and male hormones is reduced or If it is not secreted, there will be sparse or no pubic hair. The pubic hair is sparse or not long, and the vast majority of people belong to the local type of poor sensitivity. If it is caused by a disease, and the disease is cured, pubic hair will grow, and it will not affect marriage and sexual life after marriage.
growing age
Female pubic hair is located in the pubic symphysis and is distributed in an inverted triangle. From about 10-13 years old, sparse and soft pubic hair appears on the vulva, and the number gradually increases and the color gradually deepens. There are also people who don't grow pubic hair until after menstruation (or after age 18).
growth stage
female
Pubic hair is a secondary sexual characteristic of humans. In the development of women during puberty, there are two prominent developmental features, one is the breasts, and the other is the growth of pubic hair. The growth of female pubic hair is divided into six stages: Stage 1, before the age of 10, there is no visible pubic hair. The second stage, around the age of 10-11, sparsely grows long, soft pubic hair, and slightly curly hair. The third stage, 12-13 years old, the pubic hair increases, and gradually collects and curls, thick and dark in color. Stage 4, 14-15 years old, pubic hair extension covers the labia. In the fifth stage, 16-17 years old, the pubic hair expands into the pubic area and becomes an adult type. Stage 6, at age 18, pubic hair in a typical inverted triangular distribution to the inner thighs.
male
Stage 1: There is no pubic hair, and body hair grows in the same way as other general body parts.
Stage 2: A slight fluffy, straight or slightly curved pubic hair begins to appear, mainly at the base of the penis.
Stage 3: The pubic hair becomes darker, thicker, more curved, and begins to spread to the middle of the pubic area.
Stage 4: The pubic hair is similar to that of an adult, but the area covered by the hair is still narrow and does not extend to the legs. Stage 5: The growth of pubic hair reaches the state of quality and quantity of adults, and the distribution of pubic hair forms a diamond shape.
Influencing factors
basic knowledge
Chinese girls generally begin to have pubic hair at the age of 14, and by the age of 17 and 18, the density of pubic hair is basically finalized. The existence and density of pubic hair mainly depends on two factors: one is the level of estrogen and male hormones produced by the adrenal cortex in the body; the other is the sensitivity of pubic hair follicles to estrogen and male hormones. If the female pubic hair is developing, for some reason, the level of estrogen and androgen produced by the adrenal cortex is low, or the pubic hair follicles are not sensitive to estrogen and androgen, which will cause sparse or no pubic hair.
misunderstanding
The misunderstanding of pubic hair is that people know too little about pubic hair, that it is optional, or even that its presence hinders sex. In fact, among the hairs, the pubic hair is the most sexually characteristic. Pubic hair is one of the secondary sexual characteristics of adult men and women. It is not a superfluous display, nor is it "in the way". Pubic hair has its own reason.
other
In reality, the density of pubic hair varies greatly among individuals. For women with sparse pubic hair or no pubic hair, if other secondary sexual characteristics are normal (such as breast development, body shape, voice changes, etc.), menstruation is on time, indicating the development of sexual organs and sexual function. There will be no problems, can have a normal sex life, and will have a normal reproductive capacity.
Be careful not to shave your pubic hair, as it will grow harder and denser after shaving. It is recommended not to shave pubic hair.
