My GP told me that cardiovascular exercise helps with ED. I started running on the treadmill and elliptical. It did not help. But the weather is getting warmer so I started running outside. This has definately helped. I ran for 3 days and saw immediate positive results. Then I had too stop for 2 weeks and things reverted back. But now I tried running again and once again it has helped. I think you use more musculature running outside and thats the difference vs. a treadmill.
However it’'s not all good news-see my help!!! post.
