Patient's question:
Patient, male, 43 years old, in good health. Over the past year, after falling asleep at night, my penis becomes very hard, and it gradually softens upon waking up. Additionally, over the past year, my penis has become thinner and shorter. There are no other symptoms. What could be the cause?Doctor's answer:
Hello! A normal adult male penis is 7-9 cm long in a flaccid state, with an average circumference of 6.9-9.4 cm. It measures 11-16 cm in length when erect, with an average circumference of 10.8 cm. If the penis is underdeveloped or abnormally small, it can be improved through surgery.
