Why do some men have less pubic hair?

Pubic hair is one of the secondary sexual characteristics. The growth of pubic hair is the result of androgen stimulating pubic hair growth receptors. After puberty, male pubic hair not only gradually increases, but also presents a typical male diamond distribution. The growth of female pubic hair is the result of estrogen stimulation. Therefore, the distribution of female pubic hair is characterized by a flat upper edge and an inverted triangle distribution, which is completely different from that of males.

Girls have greater individual differences in body hair growth, so even if they have less or no pubic hair, it is mostly physiological, and not growing pubic hair does not necessarily hinder their development. However, if a man does not grow pubic hair, it is very likely that there is a problem of incomplete development, especially if he is over 17 or 18 years old and still has no pubic hair, then you should have a serious check-up. The key is to check whether there are any abnormalities in the size of the testicles, penis size, beard, Adam's apple, voice tone, etc.

That is to say, pubic hair deficiency is not an isolated problem, but one of a series of signs. If there are multiple other abnormal manifestations, it may mean that there is something wrong with the endocrine system or chromosomes. But if there are no other indications, it is likely that there is a problem with the receptors. When the pubic hair growth receptors are defective, the pubic hair is sparse and soft, and when the growth receptors are deficient or insensitive to androgens, the pubic hair does not grow.

At this time, it is likely to be accompanied by a thinning of armpit hair and other body hair, and there may also be a family history. This simple abnormal growth of body hair has no effect on the overall health and reproductive health. It is just a physiological variation, so there is no need to worry about it.
