We aimed to estimate the frequency of recreational use of erectile dysfunction medication (EDM) and to identify any adverse effects on confidence in gaining and holding erections resulting from such use. In addition, we explored differences in erectile function and sexual behavior between recreational and medicinal users of EDM to control for the possibility of recreational users having but not admitting erectile dysfunction. A subset from the Genetics of Sex and Aggression population-based sample of 4428 males with a mean age of 29.51 (s.d.=6.77) years provided information on their use of EDM, erectile function during first intercourse and currently, sexual behavior and confidence in their ability to gain and hold erections. There were 2.6% (n=115) recreational and 0.9% (n=39) medicinal users of EDM. Recreational users had currently significantly lower confidence in their erectile ability than non-users even though they had significantly better erectile function and significantly more unrestricted sexual behavior as well as had more confidence when initiating sexual activity. More frequent use of EDM was associated with significantly less confidence in erectile ability among the recreational users. We conclude that recreational users of EDM may be vulnerable for becoming psychologically dependent on pharmacologically induced erection.
我们旨在估算勃起功能障碍药物（EDM）的非医疗用途频率，并确定此类使用对获得和维持勃起信心的任何不良影响。此外，我们探讨了EDM非医疗使用者与医疗使用者在勃起功能和性行为方面的差异，以控制非医疗使用者存在但未承认的勃起功能障碍的可能性。基于“性与攻击行为遗传学”样本中的一个子集，该样本包含4428名平均年龄为29.51岁（标准差=6.77）的男性，他们提供了有关EDM使用情况、首次性交时及当前的勃起功能、性行为以及对获得和维持勃起能力的信心等信息。有2.6%（n=115）的EDM非医疗使用者和0.9%（n=39）的医疗使用者。尽管非医疗使用者的勃起功能明显更好、性行为明显更自由，并且在开始性行为时更有信心，但他们目前对勃起能力的信心明显低于非使用者。在非医疗使用者中，更频繁使用EDM与对勃起能力的信心明显降低有关。我们得出结论，EDM的非医疗使用者可能容易在心理上依赖药物诱导的勃起。
