What is the normal length of a male penis?

Some male friends find that the length of their penis is shorter than others when taking a bath or urinating in a public bath. This makes them begin to suspect whether there is any growth and development abnormality in their sexual organs. So, how long should the male penis be to be normal? How should the length of the male penis be measured accurately? Let's learn about the length and measurement method of the male penis.

First, how long should the male genitals be normal?

The human penis has many differences, just like the height, body shape, and facial features. It varies in length and size. Shi Chengli of China once measured the penis size of 1412 healthy young Chinese men and the erect penis length of 126 healthy men.

The conclusion is that the normalized length is 14.5 cm at most, 4 cm at most, and 8.375 cm on average; the larger diameter is 12 cm, the smallest is 4.5 cm, and the average is 8.3 cm. When erect, the largest is 16 cm, the shortest is 9 cm, and the average is 12 cm; when erect, the larger diameter is 14 cm, the smallest is 8 cm, and the average is 10.75 cm. The length of the penis of 1,000 normal adult men investigated by Liu Guozhen et al. is: the normalized length range is 4.9-8.6 cm, the average is 6.55 cm, the largest is 10.6 cm, and the shortest is 3.7 cm.

Second, male genitalia measurement

The measurement method of penis length is very important. First, measure the softness of the skin, and second, measure the changes when it becomes hard. For accurate measurement, the indoor temperature should be around 25°C. After calming down and taking a proper rest, lift the penis flat with a handle, use one end of a hard ruler to slightly press against the pubic joint, try to reduce the fat layer, and use the other end to measure the external opening of the glans urethra as the standard. The large number read is the normal length of the penis. Then use a soft ruler to measure the leg circumference of the penis 1 cm away from the coronal edge. Because patients are anxious or not suitable for the environment of the diagnosis room, they are often unable to erect in front of the doctor, so it is common to see the stretched length of the penis instead of the erect length.

In fact, when you notice that your penis is shorter than others, as long as it is within the standard value, you don’t have to worry too much, because such a situation does not mean that your penis is abnormal. It is recommended that you choose the appropriate method to accurately measure it, and then judge whether your penis is abnormal after accurate measurement.
