Negitive ions sway for a girl so I was looking at all the ion stuff I could get. I got an air purifier and water fountain for our bedroom. A personal ion generator for me. I also found ion underwear. I thought well that's where you want the ions right as close to the eggs as you can. Can't get closer I don't think. They say they help with circulation. That would help with fertility I'd think if anything. What do you guys think?
