It’s not the PD meds. It’s Just another symptom of PD. The ED meds help the physical aspect of sex, the libido aspect is another issue, but certainly treatable.

Thanks for the reply. I wondered if the meds had something to do with it.

A lot of men end up with ED, thanks to Parkinson's. So it can make a difference. For others, some Parkinson's medications may increase sex drive.
