Question
A 12-year-old boy asks, his penis size is about 3 centimeters, height is 1 meter 55 centimeters, and weight is 70 pounds. The main issue is that his penis is relatively small, and his testicles have not developed. He has consulted Nanjing Children’s Hospital and Huai’an First Hospital, but the opinions of the two are inconsistent. He is worried about his future fertility and hopes to get a definite answer.
Answer
A 12-year-old boy is still in the growth and development stage of puberty, so it cannot be simply determined whether his penis size (3 centimeters) is normal. Generally speaking, a 12-year-old boy who has entered puberty should have an erect penis length of more than 9 centimeters, which is considered normal. According to the information provided, the boy’s condition is still normal, and there is still a possibility for further growth and development. It is recommended to maintain a proper diet and engage in physical exercise. However, for more accurate information, it is suggested that he go to the hospital again for a detailed examination.
