Has anyone ever gotten pregnant while their SO was taking steroids ?

I know they say that steroids can be a form of birth control . My boyfriend takes steroids . Not faithfully, but he does a 8 week cycle or 2 per year . 
I know people are gonna have their negative thoughts on it but I don't . I support him if that is what he wants to do to make himself feel better about himself. And it does , he lightens up & is overall happier laughing at himself getting so excited about new muscles. Anyway , I just want to know does anyone else out there have a SO that takes steroids ? Have you ever gotten pregnant by a man that has ? 
Thanks :)
