How to spot a fertility scam
Look for references.
Many fertility scams will advertise that " research " has proven that a certain treatment will help you get pregnant with no side effects. Whenever you see statements about proven research, you should always look into the actual studies behind the research to make sure that the claims are not false.
For instance, check websites for direct references to medical studies. If the claims are true then the site will likely provide adequate referencing.
