Not as such unless VERY high with blood vessel damage. BUT lots of the medications that are used to lower the blood pressure have a LARGE effect on a man's virility and a smaller, but very real effect on the libido for both sexes.
There are exceptions, but these drugs can be real "downers."
I have been on antenolol and zestril for about two years. Never had any side (sexually) affects at all. Although I did ask my doctor about it and he said "it depends on the dosage and person." I guess I'm lucky.
