Patient's question:
The penis is 7 cm in length and 9 cm in circumference when not erect. After erection, it measures 13 cm in length and 12 cm in circumference. Is this development normal? Will it stop developing at this age?Doctor's answer:
Your situation is normal. The size of the penis is similar to the height and weight of a person, and there is a significant individual variation in penis size. In China, Shi Chengli measured the penis size of 1,412 healthy young Chinese men and the erect length of 26 healthy males. The results showed that the longest normal length was 14.5 cm, the shortest was 4 cm, and the average was 8.375 cm. The circumference ranged from a maximum of 12 cm to a minimum of 4.5 cm, with an average of 8.3 cm. During erection, the longest length was 16 cm, the shortest was 9 cm, and the average was 12 cm. In non-erect state, a penis length of 4 cm and 14 cm is normal for adult males. An erect length of 9 cm and 16 cm is also normal.
