What is testicular hair growth?

Pubic hair is the hair that grows on the human reproductive organs. When children enter puberty, due to the metabolism of female and male growth hormones, pubic hair begins to grow in the private parts, becoming increasingly dense and wrinkled. Pubic hair grows on the glans penis, the phalanges, and the inner thighs, generally forming a triangle. Pubic hair grows on the private parts, the phalanges, and the inner thighs, generally forming an inverted triangle. Let's discuss what happens when testicular hair grows.

The scrotum also has hair, and most men have hair on their scrotum. Because the scrotum also has hair follicles and tiny pores, but the number of pores on each person's skin is different, some people have a lot, and some people just have very few.

Throughout a man's life, there is a "player" that plays a very important role, and that is the male testicle. It looks like two "chestnuts", one on each side of the scrotum. The male testicle is an important internal organ that maintains male reproductive function and sexual characteristics. If the testicles of adult men are too large or too small, it will more or less affect the fertility function and should be taken seriously. The size of the testicle is related to age. For adolescents under the age of 12, the male testicles are in a relatively quiescent period, with a general volume of 1ml-4ml; after the age of 12, boys enter puberty and the male testicle volume expands rapidly. The male testicle volume of adult men is 16ml-25ml, with an average of 19.8ml. After the age of 60, men enter the stage of sexual decline, and their testicular volume gradually shrinks. After the age of 70, the testicular volume of men shrinks to less than 16 ml.

If the volume of both testicles of an adult male is less than 1b250l, it is microtestis, which may cause sexual dysfunction and male infertility. Too small testicles can hinder the spermatogenesis of testicles, and low sperm count or azoospermia may lead to lack of fertility. Physical examination and endocrine examination can easily show that the blood testosterone level is very low, male secondary sexual characteristics are poorly developed, such as beard, pubic hair, and armpit hair are sparse, letters are pronounced low or in a childish voice, and most people have low sexual desire and sexual dysfunction. The symptoms that lead to microtestis mainly include Klinefelter syndrome, congenital adrenal hyperplasia and some genetic diseases.
