I purchased a number of "natural" infertility books when my husband and I decided against fertility treatments. Although I think Fern may have some good ideas, it is dangerous for someone with no training whatsoever to put forth her ideas as facts. Don't eat soy? Soy is a great alternative to pesticide laced meat and poultry. I suggest books from people with SOME training. I found that most of her "don'ts" conflicted with the suggestions of professionals. Also, I found much of her suggested supplements advice worthless, as she never gives amounts/dosages. With that said, I located the yams (what could it hurt?) on the web at Frieda's, which is an African market. Good luck to all of you and stay strong.
