Viagra May Decrease Ability To Smell (Who Needs Smell When You’re Getting Some Ass?)

Higher doses of Viagra (sildenafil) may impair the ability to smell, which is possibly related to an increase in nasal congestion, German researchers report in The Journal of Urology.

“In our subjects, the most likely reason for impaired…olfactory function was nasal congestion” brought on by Viagra, the authors write. They note that, while it was not evaluated in this study, previous reports have linked Viagra with a drop in nasal airflow - probably because if you can “stay up” all night, your ass is probably too tired to breath.
