As far as my knowledge from neurobiology, psychopharmacology, and personal experience, Wellbutrin has little, if not any at all, side effect on libido. Wellbutrin is also a dopaminergic and noradrenergic reuptake inhibitor. It has no direct effect on serotonin. The dopamine pathway is one of the pathways responsible for pleasure. Thus, an increase in dopamine, such as the result of Wellbutrin, theoretically enhances the pleasurable sensation. This is why some psychiatrists may couple wellbutrin with a serotonergic agonist, such as an SSRI, to counteract the decreased libido side effect.
