Penile suspenory ligament is important to support the penis and maintain axial rigidity during intercourse. It has been speculated that patients with penile prosthesis complaining from penile instability during intercourse is due to laxity of suspensory ligament. Aim: To assess the operative outcome of strengthening of suspensory ligament in cases with laxity of suspensory ligament and loss of axial rigidity as a complication of semi rigid penile prosthesis implantation. Methods: The study was carried out on 6 penile prosthesis patients complaining of penile instability during intercourse. All patients were subjected to full history taking, general and local examination, penile length measurement before and after surgery, photographing of penis before and after surgery, IIEF-15 before and after surgery and satisfaction score for both patients and partner before and after surgery. Results: We found in all patients statistically significant improvement in erection function, intercourse satisfaction, overall satisfaction domains of IIEF-15 improved ; while orgasmic function and sexual desire remained the same. Satisfaction questionnaire for both partners improved. The penile length was shortened after the surgery in all patients. Conclusion: Corporopexy is an effective procedure for management of laxity of suspensory ligament with penile prosthesis despite the inevitable shortening of the penis.
