Patient's question:
Recently, I feel that the erection is not complete, not as firm and powerful as before. Is there any medicine I can take?Doctor's answer:
An adult penis is 11-16 cm long and 10.8 cm in circumference when erect. In a natural state, it is 7-9 cm long and 6.9-9.4 cm in circumference. For most men, sexual maturity is reached around 18 years old, and development is mostly complete by then.Advice: Maintain a healthy lifestyle, avoid frequent masturbation, and exercise regularly.
