QUEBEC CITY—A Canadian study of men with erectile dysfunction (ED) following prostate cancer therapy showed that those who received radiation therapy alone had greater success with ED treatment than men treated with radical prostatectomy alone or in combination with radiation.

The proportion of patients who felt their ED treatment was successful (defined as the ability to have sexual intercourse) was 11.2% among men treated with radical prostatectomy, 43.2% among those who received radiation alone, and 23.3% among men who received both. Study findings were presented here at the Canadian Urological Association annual meeting.
