And now, an article for the men. Dang!—it turns out Viagra has a sneaky side effect of making you feel love and not just arousal whenever you take it. In lab studies, it increases the amount of oxytocin in rats, which is a hormone associated with “feelings of love,” including nursing and childbirth as well as sexual pleasure. (This should not be confused with the drug OxyContin, which does something else entirely, and which tends to be widely abused by lab rats in the midwest.)
