Scientific Methods for Measuring Penis Length

The penis is an important part of the male reproductive organ, and the size of the penis is related to the male's self-esteem. Male friends are eager to know the length of their penis, but due to unscientific measurement methods, errors often occur. The following is an introduction to scientific measurement methods.

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.

1: Measurement of 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. 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). A length greater than or equal to 8 cm is normal.

1: The International Men's Health Organization (MTD) has concluded through nearly 30 years of research that the normal penis length M = (height T-105) * 0.618/3.14 (cm); the normal penis diameter D = M/3.14 (cm); (Europe and America = Asia/1.414/0.618) cm.

Due to obesity, there is more abdominal fat, which causes part of the penis to be buried in the fat, making the penis look smaller. When measuring, you can push the abdominal fat with your hands.
