Is there a relationship between height and genitals?

In fact, many people are now studying whether there is any relationship between height and genital size. In fact, it has been discovered that there is no direct relationship between height and genital size. The size of the genitals depends on each person's height development requirements and standards. In addition, there is no essential relationship between human sexual desire and genital size. This still comes from the body's physiological structure and normal physiological activity.

There is no direct relationship. Some people who are very tall do not necessarily have big penises. Suggestions: The normal length of the penis of an adult in my country is 3.5-12 cm, with an average of 7.1 cm. 7-18 cm when erect, average 12.4 cm

The circumference of the penis of normal people in my country is 5.5-11 cm under normal conditions, with an average of 8.1 cm. When erect, it is 8-14.5 cm, with an average of 11.1 cm. The length and circumference of the penis are normal within the above range. Abnormalities generally require surgical treatment.

1. Function of testicles

(1) Sperm production

The seminiferous tubules of the testis are where sperm are produced. It takes about 2 months for human spermatogonia to develop into sperm. If the sperm count is less than 20 million/ml of semen, it is difficult to get pregnant.

(2) Secretion of androgen

Leydig cells of the testes synthesize and secrete androgens, mainly testosterone. Testicular supporting cells synthesize and secrete inhibin. There is also a structural close relative of inhibin - activin.

2. The role of testosterone

(1) Testosterone

①Maintain spermatogenesis.

② Stimulate the growth, development and maturation of reproductive organs.

③ Promote the appearance of secondary sexual characteristics and maintain normal sexual desire.

④ Promote protein synthesis, increase calcium and phosphorus deposition, promote bone and muscle growth; enhance bone marrow hematopoietic function, increase red blood cells; and cause water and sodium retention.

(2) Inhibitors

Inhibin has a strong inhibitory effect on the secretion of FSH from the pituitary gland (physiological doses have no significant effect on LH).

Activin, a structural analogue of inhibin, promotes the secretion of FSH from the pituitary gland.
