Abstract

Background: Penile prosthesis (PP), or penile implant, is one of the oldest effective treatments for the condition of erectile
dysfunction and a Penile implant is always seen as a tool to provide rigidity in the penis with no other effects regarding the ejaculation.
Aim of the study: To assess any change in ejaculatory function after penile prosthesis implantation (PPI)
Patients and Methods: 40 male patients with erectile dysfunction scheduled for malleable penile prosthesis implantation
(PPI) were included in this study. The mean age of patients was (52.5 ± 12) years. Patients were married and in a stable
relationship. We excluded patients with anejaculation or patients’ candidates for re-implantation following a complicated PPI.
All patients were asked to sign an informed consent, Stating the intravaginal ejaculation latency time (IELT) before PPI and
after six months of regular coitus following the operation. Patients were asked to Fill-in the Index of Premature Ejaculation (IPE). and Premature Ejaculation Diagnostic Tool Questionnaire (PEDT) before PPI and after six months of regular coitus following PPI.  Results: Our study found PPI to increase ejaculation latency in patients who had IELT less than 12 minutes before PPI. This is especially important in patients with acquired premature ejaculation (who experienced a reduction in latency time usually less than 3 min.). In the current study, the percentage of premature ejaculation (PE) decreased from 8 patients (20%) before the operation to 3 patients (7.5%) after the operation with a highly statistically significant difference.  Conclusion: PPI does not interfere with ejaculation or orgasmic function in ED patients. Ejaculation latency time may be increased in men with rapid ejaculation (less than three minutes) or moderate ejaculation time (3-12 min), however, few men after PPI may still suffer PE. PPI for ED patients with concomitant PE may offer an added value in delaying ejaculation after the operation.
