For Chinese adult males, the average length of the penis in the soft state is about 5~6cm, and the average length of the penis in the erect state is 11~13cm.
The average girth of the penis is 8.3cm in the soft state and 10.7cm in the erect state, and it is generally considered that a penis is short if its length is less than 4cm in the soft state and less than 7cm in the erect state.
Generally speaking, as long as the length of the penis is within the normal range, it will not affect the experience of sexual life, while patients with a short penis who are not satisfied with their sexual life or are unable to have sex will need to undergo surgical treatment.
It is important to note that when measuring the length of the penis it is important to pay attention to the correct method of measurement. The correct measurement is to use a straightedge against the pubic symphysis and measure the full length from the pubic symphysis to the head of the penis.
If there is any abnormality in the length and development of the penis, it is recommended to consult a doctor in a timely manner and have standardized treatment under the guidance of a professional doctor.
