Hi and welcome. Having an enlarged prostate may be annoying, but it does not cause erectile dysfunction. However, certain treatments for enlarged prostate can raise the risk for problems getting and sustaining an erection.
If you have one, have you checked your PSA lately?
Hi S, If your your doctor suggests that you start on medication to treat your enlarged prostate, it probably means that your symptoms are bothersome and are unlikely to resolve with time. It could also mean that they are so severe that you can't tolerate them, or that they are resulting in a back-up of urine. Experts, however, caution against rushing into starting BPH medication before it is needed.
BPH Benign Protatic Hypertouphy.
So the longer you have this enlaged protate, it will efect your erections.
Good Luck
