Why is my pubic hair becoming less and less?

Both men and women have pubic hair, but the amount of pubic hair varies from person to person. Some people have sparse pubic hair, while others have thicker pubic hair. So what happens if pubic hair suddenly becomes less and less?

The amount of pubic hair in men and women is often an important indicator for diagnosing disease. The amount of pubic hair varies greatly between men and women. Generally speaking, women have less pubic hair than men. Female pubic hair usually appears when the breasts begin to develop, first appearing on the labia majora and then developing to the mons pubis triangle area. The distribution of pubic hair is an inverted triangle. Armpit hair grows after pubic hair appears and before menarche.

Too little or too much pubic hair mainly manifests itself in women. Normal women have less body hair, most of which is physiological. There are no major diseases in the body and it has no impact on health. Having too little pubic hair is a pathology in a few women. There is a genetic disease called Nayson syndrome caused by sex chromosome abnormalities. The disease often causes very little pubic hair. Female patients with this disease have hypogonadism, short stature, underdeveloped breasts, childish external genitalia, almost no pubic hair on the mons pubis, amenorrhea, and no fertility. Some women have hypothyroidism, often have no armpit hair, sparse pubic hair, and have low libido. Some women also experience heavy postpartum bleeding, pituitary ischemia, pituitary insufficiency, amenorrhea and infertility, weight loss, weakness, loss of libido, loss of hair and pubic hair, and less pubic hair.

When men and women have less pubic hair or pubic hair falls out, they should go to the hospital for examination in time. Some young men may have sparse or absent pubic hair, often without Adam's apple, high-pitched voice, and no sperm in their semen. This is caused by congenital testicular dysgenesis or microtestis. If men experience the above symptoms, they should go to the hospital for a chromosome test to determine the cause as soon as possible.

Some women have excessive hair growth, which is often a sign of disease. Women with eosinophilic or alkaliphilic pituitary adenomas often have hirsutism in the pubic area. The former has sausage-like fingers, thickened gums, enlarged tongue, and gonadal dysfunction; the latter has a full-moon face, a drum-like belly, rough skin, and is accompanied by amenorrhea and hypertension. Women with adrenal cortical hyperplasia and tumors have excessive secretion of male hormones, which can cause excessive pubic hair and clitoral hypertrophy. Polycystic ovary syndrome can also cause excessive hair growth, which is characterized by a slight amount of hair at the beginning, and a significant increase in pubic hair and body hair after the onset of amenorrhea, oligomenorrhea, obesity, infertility and other conditions. In addition, people with hereditary hirsutism, drug-induced hirsutism, and neurogenic hirsutism should be examined and diagnosed in a timely manner.
