If ferritin is kept constantly under control, it greatly increases the chances of staying fertile. I believe that antioxidants also can play a positive role in keeping the pituitary healthy. I also like the natural chelators like IP6 and green tea extract, as they can penetrate areas where other chelators have problems, helping to keep iron under control in places like the glands and brain. Fermented Papaya Preparation (FPP) is also a very intriguing development. I wish I could have heard Prof. Eliezer E. Rachmilewitz speak at the recent conference in Turkey, as he is a top expert in nutrition and antioxidants. He has done much research into the effects of FPP. Hopefully, we will eventually hear some updates from the conference on this topic.
BMT definitely is more of a threat than thal to fertility if the patient is well compliant with a good treatment program. This is one factor to be considered, but there are also positive factors, like being cured. It is not an easy decision to make.
