Why does the penis grow hair?

The penis is a unique organ of men. When it matures, hair will grow around it. This is called pubic hair. The growth of pubic hair is normal, but many teenagers will have anxiety due to lack of sexual knowledge, which may even affect their studies. Generally, men will have pubic hair after the age of 14, and it will basically grow by the age of 18. Next, let's talk about why the penis grows hair?

Generally speaking, after the onset of puberty, adolescents will grow pubic hair due to the effects of estrogen and androgen. The androgen in the male body is secreted by the testicles, and there is also a certain amount of estrogen in the female body, which is secreted by the adrenal cortex and ovarian stroma. Whether male or female, the presence and density of pubic hair are related to the level of estrogen androgen in the body, as well as the sensitivity of the pubic hair follicles to estrogen androgen. For those who simply do not grow pubic hair but are normal in other aspects, it may be due to the insensitivity of the pubic hair follicles to their own estrogen androgen. This is not pathological and has nothing to do with it. It does not affect physical health, marriage, and fertility. Therefore, there is no need to worry about it, and don't believe those nonsense.

Stage 1: No pubic hair, body hair growth is the same as other general body parts.

Stage 2: Slightly loose, straight or slightly curved pubic hair begins to appear, mainly at the base of the penis.

Stage 3: Pubic hair becomes darker, thicker, and more curly and begins to spread to the middle part of the pubic area.

Stage 4: Pubic hair is similar to that of adults, but the area covered by the hair is still narrow and has not extended to the legs.

Stage 5: Pubic hair growth reaches adult quality and quantity, and the distribution of pubic hair forms an inverted triangle.
