ABSTRACT
INTRODUCTION: In recent years, recreational use of phosphodiesterase type 5 (PDE5) inhibitors has become popular as a sexual enhancement aid among some men without erectile dysfunction (ED) and even among women. AIM: The aim of the present study, therefore, was to investigate the recreational use of PDE5 among young and healthy men. MAIN OUTCOME MEASURES: We evaluated the use of PDE5 inhibitors among young and healthy men, their main reasons for using these drugs, and their expectations regarding its effects. METHODS: A survey was carried out among 167 male medical students (21.2 +/- 2.3 years, range 17-31). The surveys were divided into domains, assessing epidemiological data, use of PDE5 inhibitor, and the simplified International Index of Erectile Function (IIEF-5). RESULTS: All men considered themselves with perfect erectile function. However, 9% reported previous use of PDE5 inhibitors. Of these, 46.7% had used PDE5 inhibitors more than three times, and 71.4% had mixed them with alcohol. Among this group of men, 13.3% had ED according to the IIEF-5. ED occurring with condom use, however, was twice more common, and 71.4% of the men who had taken PDE5 inhibitors thought that the drug had potential to facilitate condom use. CONCLUSION: In conclusion, the use of PDE5 inhibitors by young men is more frequent than previously reported. Condom-related ED seems to be an underestimated problem, frequently solved with PDE5 inhibitors. However, potential deleterious effects might exist. Because PDE5 inhibitors are being used as non-prescribed drugs by as much as 9% of young men, further studies must evaluate the effects of these drugs in young and healthy men.
