Context
What is the effect of different treatment options for benign prostatic hyperplasia (BPH) on sexual function or dysfunction? With increasing age, sexual dysfunction and BPH become more prevalent. Some treatments for BPH can affect sexual function. Different surgical treatments have different effects on sexual function depending on how much the internal involuntary sphincter is affected. The same is true for medical therapies, each class of drug having a unique affect on sexual function.
Starting point
In the past, many articles suggested a causal relation between BPH and sexual dysfunction. But a recent report by H Leliefeld and colleagues (BJU International 2002; 89: 208–13) confirms the idea that the relation is coincidental. Prospectively, these investigators examined patients at baseline and 9 months after various treatments for BPH with questionnaires on voiding symptoms, related complications, and sexual function. 84% of patients reported no change in sexual function. All treatments showed both improvement and deterioration in 3–14% and 0–16% of patients, respectively. As expected, age was the most important determinant of sexual function. In addition, the effect of severe irritative symptoms or the presence of urological comorbidity, such as bladder stones, increased the rate of sexual dysfunction. In this study, most patients underwent surgical therapy or watchful waiting while fewer had medical therapy. Too few patients had minimally invasive procedures to comment on their effect on sexual function.
Where next?
Thus the relation between treatment of BPH (or watchful waiting) and sexual dysfunction is usually coincidental, unless symptoms become severe or complications (such as bladder stones or urinary retention) develop. More prospective studies are needed to assess the effect of BPH and its treatment on sexual function. Medical therapy is now more common than surgery in developed countries and treatment of BPH is commonly advocated for improvement in quality of life. Therefore any effects on sexual function become even more important. As minimally invasive surgical operations become more common, more data will be required for such interventions. The difficulty will be in keeping up with the rapidly evolving techniques of minimally invasive therapies
