Minoxidil as a treatment for ED

Is it possible that oral min has an impact on prolactin levels and erectile dysfunction? I swear I started developing symptoms only on oral min and no fin, not able to sustain an erection.

Yes, minoxidil can increase prolactin levels in women and impact their menstrual cycle. From what I read, it has no impact on testosterone and there are no reports that it can cause sexual dysfunction in men. In fact, the vasodilatation associated with minoxidil may be a reasonable treatment for erectile dysfunction according to some reports.  Maybe you are having a placebo side effect?
