There is no clear standard for the length of male genitalia to speak of, and it may be related to race, weight and other factors. The length of Asian male genitals is generally 4~12cm, and obese men may have 1~3cm less genital length than average men. 1. Race: The genital length of Asian men is less than that of European and American men, and the individual differences are also relatively large. China’s adult males in the soft state, the length of the genitals is generally 6 ~ 8cm; in the erectile state, the length of the genitals is generally 10 ~ 12cm, in the length of 1 ~ 2cm below or above 1 ~ 2cm are considered to belong to the normal length. 2. Body weight: The length of male genitals and body weight are also related. If a man is more obese, then his fat will be a little thicker, which may bury part of the genitals, resulting in the genitals being 1 to 3cm less than the standard length. So if a man is more obese which affects the length of his genitals and thus affects his sex life, he can get his genitals back to length by exercising, controlling his diet and reducing his weight, if the above methods are not effective, it is recommended to go to a regular hospital for treatment.
