Rotterdam: Rotterdam: The impotence drug Tadalafil is being studied by doctors in Holland to treat prostate cancer patients.

Prostate cancer which can be cured by surgery and radiotherapy often leaves sufferers with nerve damage leaving them impotent.

But the study, carried out at the Erasmus MC-Daniel den Hoed Cancer Center in Rotterdam, published in the International Journal Of Radiation Oncology Biology Physics says that successful sexual relationswere reported in 48 per cent of the survivors who took Tadalafil versus 9 per cent of the men who were given placebo. Sixty-seven per cent of patients reported their erectile function improved versus 20 per cent of the placebo group.
