Hi I am bhupendra from in nepal I have a question...

Treatment
In fact, there are many methods that are used to increase the size of the penis, but they are not very useful, as there are some medical centers that perform some cosmetic surgeries whose goal is to increase the size of the penis or increase the thickness of the penis. These methods include the following:

Penile injection with silicone or surgical treatment to replace ligaments in the penis in some cases.

The normal length of the penis varies according to genes, body structure, hormones, and the person’s age. The normal length of the penis ranges from 4-8 cm when flaccid and 10-18 cm
when erect
Diagnostic tests:
Undergo a medical examination by a specialist doctor if the length of the penis is less than the normal range, for the purpose of conducting a medical examination and taking your medical history, and in some cases a testosterone analysis can be done.
