Erection, orgasm, and ejaculation are three independent functions. Men who are impotent from vascular causes continue to have an orgasm and ejaculation with a soft penis. Therefore, restoring erections with a prosthesis in that individual will result in a patient that continues to have an orgasm and ejaculation. Patients have fathered children with an implant.
A patient suffering from ED following radical prostatectomy or radiation therapy loses the ability to have erections and ejaculation. Therefore an implant in that scenario will result in a patient that has an erection and orgasm but no ejaculation.
No, 50% of patients undergoing this procedure are diabetics.
The erection with the implant is identical to an erection post injection. The difference is in the flaccid penis. A penis with an implant will never be as small/short or soft as a penis without an implant. Patient satisfaction with the erection is much higher with implants than with injections.
