How can I fix this?

Surgery

Pros: quick time

Cons: penis length reduction, risk of recurrence

Penile infiltrations

Pros: drug directly on site

Cons: microtrauma on the T.A., therapeutic continuity over time, loss of working hours, prolonged treatment over time

Non-invasive medical therapy (IdroBrea)

Pros: convenience of home therapy, therapeutic continuity over time, treatment of the entire affected organ (T.A.)

Cons: prolonged treatment over time (but at home!)
