Chinese men's standard size

Men are more concerned about the size of their penis. A small penis will make men feel insecure. The size of the penis has a great impact on the quality of life of couples. Some men's penises are big, some are small, and it is not clear how long it is considered normal. So what is the standard size of a man's penis? What is the normal size of a man's penis?

1. Chinese men's penis standards

The male genitals of people are different from each other in height, weight, and size of facial features. In 1950, China measured the penis size of 1,412 healthy young men. The conclusion was that the maximum penis size was 14.5 cm, the shortest was 4 cm, and the average was 8.375 cm; the average diameter was 8.3 cm; and the average penis size was 12 cm when erect. This large number became the basis for Chinese condom manufacturers to divide the model specifications at that time.

In 1990, relevant authoritative experts conducted precise measurements of the male genitals of 2,547 male college students aged 16 to 40. The average length was 7.43 cm, the average diameter was 8.17 cm; and the average value when erect was 13.34 cm.

There are also scientific studies that emphasize that the average length of the male genitals in my country is 8.08 cm, the diameter is 8.11 cm, and the average length when erect is 12.4 cm. This precise measurement result is often related to the selection object and measurement method, so it can only be used as a reference.

In addition, the length of the penis of the same person is not stable under normal circumstances. For example, anxiety, severe cold or severe fatigue can cause the penis to shorten.

In clinical medicine, a boy is considered to have developmental abnormality if his male genitals are shorter than 2.5 cm before puberty and shorter than 5 cm after puberty, and if he has abnormal growth and development and no erectile function; in addition, his secondary sexual characteristics are incompletely developed and he has erectile dysfunction.

2. Formula for calculating whether the penis size is normal

The International Men's Health Organization (MTD) has calculated based on nearly 30 years of scientific research:

The normal penis length m=(height t-105)*0.618/3.14 (cm).

The normal vaginal diameter is d=m/3.14 (cm).

(America = Asia/1.414/0.618) cm.
