why can't the penis be enlarged?

Hello,

Welcome to the ehealthforum and I am really glad to help you out.

The size of an erect penis usually over 2 inches is normal. No scientific research supports the use of any non-surgical method to enlarge the penis, and no reputable medical society endorses penis surgery for purely cosmetic reasons. The techniques you see advertised can damage your penis, and some may even cause erectile dysfunction (impotence). Hence penis cannot and should not be enlarged.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
