How long is the penis when erect? To measure the length of an erect penis: Stand upright, pinch the glans penis with your hands and pull it forward until it can no longer be extended. Use a ruler to measure the length from the pubic symphysis to the glans penis (the length after pulling is basically the same as the length when erect).

The International Men's Health Organization (MTD) has developed a formula for calculating whether the penis size is normal through nearly 30 years of research (Asia):

Normal penis length M = (height T-105) * 0.618/3.14 (cm) Normal penis diameter D = M/3.14 (cm) (European and American = Asian/1.414/0.618) cm

The above formula is only calculated based on most statistics. Actual data proves that penis length has nothing to do with height. The size of the penis is more closely related to race and genetics.

There are many differences in penis size, which are related to ethnicity and race. Many factors may affect the normal size of the penis, including excessive body fat, cold weather, and stressful situations. Different lengths and thicknesses are normal physiological phenomena. The length of the penis has nothing to do with male sexual ability, nor is it a factor that affects women's sexual pleasure. In general medicine, it is believed that a male penis longer than 5 cm can perform normal sexual function. The normal (non-erect) penis length ranges from 4.5-8.6 cm.

The length of the penis (non-erection) of Chinese men (18-45 years old) is between 4.5-10.1 cm, with an average of 6.6 cm, an average of 2.5 cm in cross-sectional diameter, and an average of 8 cm in circumference in the middle of the penis. Shi Chengli of China once measured the penis size of 1,412 healthy young Chinese men and the length of the erect penis of 126 healthy men. The results showed that the longest penis was 14.5 cm in normal state, the shortest was 3 cm (fat man), and the average was 8.375 cm; the circumference was 14 cm at most, 2.5 cm at least, and 7.3 cm on average. The longest penis was 23 cm at most and 8 cm at least when erect; the circumference was 14 cm at most and 8 cm at least when erect, and the average was 10.75 cm. Liu Guozhen et al. investigated the penis length of 1,000 normal adult men: the normal length range is 4.9-8.6 cm, the average is 6.55 cm, the longest is 11.6 cm, and the shortest is 3.7 cm. Another scholar measured the penis of 2,547 male college students aged 16-25, and the average length was 7.43 cm, the average circumference was 8.17 cm; the average penis length was 13.34 cm, which is similar to the calculated erection length of 13.08 cm, so the length can be considered to represent the length after erection.

The above is the introduction about the normal length of the penis when it is erect. I believe that after reading the above introduction, you already know how long the penis is when it is erect. Of course! The length of the penis when it is erect cannot indicate whether a person's sexual function is good. In addition, it needs to be judged from many aspects.
