Patient's question:
Patient is male, 37 years old, and infertile.Doctor's answer:
Generally, a normal adult penis measures 7-9 cm in length when flaccid and 6.9-9.4 cm in circumference. When erect, it is about 11-16 cm long, with an average circumference of 10.8 cm. If the penis is less than 5 cm in length when flaccid and less than 10 cm when erect, it can be classified as micropenis. Males typically reach full development around the age of 22. For sexually mature males, penis elongation can only be achieved through surgery.
