This study significantly extends understanding of the effects of long-term treatment with these drugs on sexual function in men with lower urinary tract symptoms associated with benign prostatic hyperplasia. Treatment with finasteride or combined therapy was associated with worsening sexual function while treatment with doxazosin alone was associated with minimal negative impact if any. Physicians should discuss with their patients the possible long-term effects of these drugs for lower urinary tract symptoms associated with benign prostatic hyperplasia on sexual function.
