A trial to see if the early use of tadalafil can help with sexual function after surgery for cancer of the prostate

This trial looked at using tadalafil in men after surgery for prostate cancer. It is for men who had prostate surgery (prostatectomy) that was nerve sparing. After this type of operation some men may have problems getting erections. You may hear this called erectile dysfunction. This means you are not able to get an erect penis, or keep it erect enough for sexual activity.

We know from research that tadalafil helped men with erectile dysfunction between 1 and 4 years after surgery. But doctors were not sure if giving tadalafil sooner after surgery could help.

In this trial the researchers compared tadalafil with a dummy drug (placebo) soon after surgery to see if tadalafil helped men to keep their erectile function.
