Does Peyronie's disease cause impotence or difficulty maintaining an erection?

The presence of simultaneous curvature and erectile dysfunction is one of the main reasons why the patient seeks specialized treatment.

This can happen for different reasons:

1. PainIn the acute phase, pain during erection can hinder the patient, making it difficult to maintain rigidity.
2. Difficulty in PenetrationThe physical deformity itself can prevent sexual intercourse, leading to anxiety and loss of erection.
3. Structural and Biomechanical Changes (Instability)This is a very important factor. Fibrosis alters the geometry of the penis, creating “weak points” that compromise axial rigidity (the ability to remain straight and firm for penetration):
   • In cases of Narrowing (Ampulheta): The penis loses structural support at that point. During penetration, it can “fold” or “collapse” in this thinner area, even though the rest of it is rigid.
   • In cases of curvature: When trying to penetrate, the force is concentrated on the inner (concave) side of the curve. This side “sinks in” or loses its tension, leading to loss of erection.
   • Veno-occlusive failure: The fibrous plaque itself can prevent the penis from “capturing” the blood properly, reducing overall rigidity.

The treatment for erectile dysfunction associated with Peyronie varies. It may include oral medication, injections, or the implantation of a penile prosthesis.
