The issue of the length of men's "there" has been a concern since ancient times. Some men, out of curiosity, secretly compare the size of their penis with those around them in the bathtub. Once they discover that their penis is short and small, they will experience inferiority complex.
In fact, there are many differences between a person's penis and their height, weight, and facial features. In 1950, the penis size of 1412 healthy young men was measured in China. The results show that under normal conditions, the longest is 14.5 cm, the shortest is 4 cm, and the average is 8.375 cm; The average circumference is 8.3 cm; The average time of erection is 12 centimeters. This number became the basis for domestic condom manufacturers to classify models at that time.
In 1990, relevant experts measured the penis of 2547 male college students aged 16 to 40 years, with an average length of 7.43 centimeters and an average circumference of 8.17 centimeters; The average time of erection is 13.34 centimeters. Other studies have pointed out that the average length of the penis in Chinese men is 8.08 centimeters, the circumference is 8.11 centimeters, and the average effective length of an erection is 12.4 centimeters. These measurement results are related to the selection of objects and measurement methods, so they can only be used as a reference. In addition, the length of the penis of the same person is not constant under normal conditions, such as tension, cold, or severe fatigue, which can cause the penis to shorten.
Clinically, the penis is shorter than 2.5 centimeters before puberty and less than 5 centimeters after puberty, and has abnormal development and no erectile function; At the same time, the second sexual sign of dysplasia, sexual dysfunction, can be considered as abnormal penis development.
