Ninety-nine males were included, mean age 70.6 y. The results demonstrate that 17% of patients lost a sexual activity that they had preoperatively, and no one regained sexual activity after surgery , A correlation between increasing age and risk of losing sexual activity w as demonstrated. 26.1% lost a normal erectile function they had preoperativ ely, while 6.7% regained normal erections.
