What is the normal length of the penis?

For men, they are more concerned about the length of their penis. They are always worried or afraid that their penis is short and will affect the sex life of the couple. But in fact, there is no unified standard for penis length in China, and the length of male penis is also different in different countries.

1. There is no unified standard in China for the normal length of the penis. Congenital micropenis is a very rare disease. Its cause may be related to insufficient androgen secretion during pregnancy and genetic factors. It can only be diagnosed after a doctor's examination. But it is worth noting that many adolescents and even adult men who are concerned about the size of their penis have normal penis anatomy.

2. The size of the penis varies greatly among individuals. Professor Wang Yixin, President of Shanghai Union Hospital, once measured the length and diameter of the penis of 283 normally fertile men in a non-erect state. The length of the penis from the pubic surface of the lower abdominal wall to the glans penis ranged from 4 to 12 cm, while the diameter of the lower part of the coronal sulcus of the penis ranged from 2.1 to 3.2 cm.

3. The Shanghai Family Planning Technical Guidance Institute also conducted measurements on 900 newly married men. The results showed that the longest penis length in the non-erect state was 11 cm, the shortest was 3 cm, and the average was 6.9±1.4 cm; the maximum penis diameter was 4.0 cm, the minimum was 1.5 cm, and the average was 2.5±0.3 cm.

4. Data from the United States show that the average length when erect is 5.7 inches, 70% of people are in the range of 4.7 to 6.3 inches, 15% are less than 4.7 inches, and 15% are greater than 6.3 inches. The circumference is 3.9 to 5.9 inches, with an average of 4.7 inches. These data were published in the American Journal of Urology and show that black Americans have larger penises than white Americans. Other assessments show that Asian men are smaller.
