Study predicts risk of impotency after prostate cancer treatment

DOCTORS can advise men undergoing prostate cancer treatment with more certainty about their future sexual function. 

Researchers longitudinally studied 1000 men undergoing prostatectomy, radiotherapy or brachytherapy to develop a model predicting erectile dysfunction two years after treatment.

They found that better pre-treatment sexual functioning scores, younger age, lower PSA levels and lower BMI were associated with functional erections after two years. The model was validated in 1200 community-based patients.

“This study provides formulas which will make predicting the outcome much more certain,” Dr Stephen Ruthven, president of the Urological Society of Australia and New Zealand, said.
