Promises from doctors about this regarding their drugs dealing are likely to contain misinformation from the drug companies themselves.
The doctors often just repeat, as the drug companies are allowed to buy them lunches, advertise to them, they buy the top doctor professors to teach the benefits of their drugs to students. They surely influence the medical learning books, pay through the universitys, pay the drug regulators and so on and on. So unfortunately as found guilty in trials. You may find your doctor simply prescribing you wellbutrin as something that may actually improve your sex life. In reality there has no been no study to suggest that. There may have been studies that wellbutrin has caused sexual dysfunction, but at a lower rate than some other antidepressants.
thats all doctors and their drug company backers need for them to claim it is good for sex.
