What is the normal length of the penis?

The penis is a symbol of a man's ability. Many men are curious about the length of their penis. Is it normal? Or is it longer or shorter than the standard? In fact, there are two types of penis length: the normal penis length and the penis length when the man is erect. Let's popularize this knowledge!

The scientific way to measure the length of the penis is from the pubic bone to the glans penis. There are two common methods used by doctors:

1. Measurement of non-erect penis length: At room temperature of 18°C, stand upright, lift the penis to 90° with the body, and use a ruler to measure the length from the pubic symphysis above the penis to the top of the glans penis.

The second is to measure the length of the erect penis: stand upright, pinch the glans penis with your hands and pull it forward until it can no longer be extended, and use a ruler to measure the length from the pubic joint 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.

It can be seen that the normal standard of penis is different in different regions, and it is not the same standard. In fact, the length of the penis cannot fully prove the ability of men. As long as men are confident enough and their penis is healthy and free of male diseases, it is enough. This can guarantee a pleasant sex life and normal fertility.
