OBJECTIVE: To evaluate quantitatively and qualitatively the degree of sexual dysfunction in an unselected population of men attending a prostate-assessment clinic using a sexual-function inventory, and to ascertain the degree of correlation between sexual dysfunction, urinary symptoms and age. PATIENTS AND METHODS: In all, 168 men with symptomatic BPH attending a prostate assessment clinic were investigated prospectively using the International Prostate Symptom Score (IPSS), BPH Impact Index (BPHII), a measurement of urinary flow rate and residual urine volume, and a sexual function questionnaire. The results were assessed using Spearman's rank order correlation to discern any correlations between the measured variables. RESULTS: The data from 140 patients were available for analysis; of these, low scores were obtained in 59% for sexual drive, in 56% for erections (with 46% of men satisfying the National Institute of Health criterion for impotence) and in 38% for ejaculation. There was a statistically significant rank order correlation between age and the sexual symptom scores for each of the three categories (sexual drive, erection and ejaculation), but no correlation between age and the problem assessment scores for these domains, suggesting that the older patients are just as bothered by their sexual dysfunction as the younger men. Furthermore, the BPHII scores correlated weakly but significantly with all aspects of sexual function, including overall sexual satisfaction, in contrast to the poor correlation seen with the total IPSS and sexual function scores. CONCLUSION: There is a significant number of patients with symptomatic BPH who have sexual dysfunction, with the proportion increasing with advancing age and with the older men still showing a high degree of bother from their symptoms. Sexual function scores were better correlated with BPHII scores than with the total IPSS, although some of the individual IPSS questions correlated well.
