13 The little girl has pubic hair

If pubic hair appears on a little girl, parents will feel very nervous and anxious, especially when puberty has not yet arrived. If these problems appear, it means precocious puberty, which will have a certain impact on their physical development. This should be paid attention to. Only a few girls have pubic hair growing prematurely due to certain diseases.

Pubic hair is one of the secondary sexual characteristics of the human body. Pubic hair begins to appear in girls between the ages of 11 and 12, and in boys between the ages of 12 and 15. If pubic hair does not grow or is sparse at this time, it is medically called alopecia. Women with alopecia are commonly known as "white tigers", and men with chest hair, navel hair and pubic hair connected into a single line are called "blue dragons". In the old society, there were sayings that "blue dragons and white tigers are unlucky" and "men with alopecia will kill their wives, and women with alopecia will kill their husbands", which are pure nonsense. This puts a lot of mental pressure on patients, and some even dare not to fall in love.

puberty

Generally speaking, after the onset of puberty, pubic hair grows from the pubic follicles of adolescents due to the effects of estrogen and testosterone. The androgens in men are secreted by the testicles, and there is also a certain amount of estrogen in women, which is secreted by the adrenal cortex and ovarian interstitium. Whether male or female, the presence and density of pubic hair is related to the level of estrogen and androgen in the body, as well as the sensitivity of the pubic hair follicles to estrogen and androgen. For those who simply do not grow pubic hair but are normal in other aspects, it may be that the pubic hair follicles are insensitive to their own estrogen and androgen. This is not pathological and has nothing to do with anything. It neither affects your physical health nor your marriage or fertility. Therefore, there is no need to worry about it, and don't believe in those nonsense.

Disease issues

Of course, in a very small number of people, it may be caused by disease, such as hypothyroidism, and the pubic hair may be sparse. For example, inflammation, tumors or trauma may cause structural damage and functional impairment of the hypothalamus-pituitary-adrenal axis, thus affecting the secretion of sex hormones. Or it may be due to congenital diseases or some unexplained diseases.

For example, idiopathic Addison's disease affects the secretion of sex hormones, which manifests as menstrual disorders, amenorrhea, sparse pubic hair, and sexual dysfunction. For example, the influence of drugs. Long-term and large-scale use of glucocorticoids before puberty will feedback inhibit the function of the hypothalamus-pituitary-adrenal axis, causing renal cortex dysfunction or even atrophy, and reduced or no secretion of estrogen and androgen, resulting in sparse or no pubic hair.

Pubic hair

Most people have sparse or no pubic hair, and they have poor local sensitivity. If it is caused by a disease, pubic hair will grow again once the disease is cured, and it will not affect the marriage and sexual life after marriage.

Age of growth

Women's pubic hair is located at the pubic symphysis and is distributed in an inverted triangle shape. Starting from around 10-13 years old, sparse and soft pubic hair appears on the vulva, which then gradually increases in number and becomes darker in color. Some people grow pubic hair after their menstruation (or after the age of 18).
