How long is a normal penis erection?

The penis can only complete sexual intercourse when it is erect. In the eyes of many people, the length of the erect penis has a great relationship with the quality of sex life. Therefore, when they are dissatisfied with their sex life, many men worry that their penis is too short and are very concerned about the length of the normal erect penis. So, how long is the penis after erection? Let's take a closer look.

The size of the penis varies among races and individuals. The length of the penis (non-erection) of Chinese men (18-45 years old) is between 4.5-8.8 cm, with an average of 6.5 cm, an average transverse diameter of 2.5 cm, and an average circumference of the middle part of the penis of 8 cm. Generally speaking, the male penis, like the height, weight and thinness of the body, has great individual differences. Shi Chengli in China once measured the penis size of 1,412 healthy young men in China and the erect penis length of 26 healthy men. The results showed that the longest was 14.5 cm in normal state. The shortest was 4 cm, with an average of 8.375 cm. The maximum circumference was 12 cm, the minimum was 4.5 cm, and the average was 8.3 cm. When erect, the longest was 16 cm, the shortest was 9 cm, and the average was 12 cm.

How to measure the length of the penis?

Here is a method commonly used by doctors. To measure the length of a non-erect penis: At room temperature of 25°C, stand upright, lift the penis to a 90° angle 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. 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, and 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 of the erect penis). It is worth reminding that some men are obese and have more abdominal fat, so part of the penis is buried in the fat, making the penis look smaller. When measuring, you can use your hands to push the fat in the lower abdomen. However, men with smaller penises don’t have to worry about it, as it will not affect their sex life as long as they use the right method of making love.

The formula to calculate whether the penis size is normal!

The International Men's Health Organization (MTD) has concluded through nearly 30 years of research:

Normal erect penis length M = (height T-105) * 0.618/3.14 (cm)

Normal erect penis diameter D = M/3.14 (cm)

The above is an introduction to the length of the penis after erection. I hope it will be helpful for men to understand. There is no fixed value for the length of the erect penis. The length of the penis in the erect state is different for men of different physiques, but there is also a normal range of values. You can compare it according to your own situation. If it is too short, you can get appropriate treatment.
