I was unable to find any suggestion that anticoagulants cause ED. ED is cited as a rare side effect that occurred in less than 2% of the men using Lipitor (Atvorstatin). So it doesn't look like these medicines would be related to problems with ED. However, the best way to know for sure is to talk to your pharmacist or the doctor who prescribes these medications.
