A mild curvature of the penis is common and often does not require treatment if erections are normal and intercourse is possible. However, if the curvature is significant enough to make penetration difficult, causes pain, or has worsened over time, it may be due to a condition such as Peyronie's Disease. Unfortunately, there is no simple tablet that reliably corrects penile curvature. Treatment depends on the severity and may include observation, specialized medications prescribed by a urologist, traction therapy, or, in some cases, surgery. I recommend consulting a urologist for a proper examination and assessment of the degree of curvature so that the most appropriate treatment can be advised.
