year family legacy of HD. He has been talking about babies a lot lately but he is afraid to get tested and I don't know how to ease him into it. - Krystin (23) Hi Krystin, Thanks for your question. If you are thinking of having children but your husband doesn't want to have the test, there is a way you can do this without risking passing on the HD gene, without him having to know whether he has the HD gene or not. I know it sounds weird or not possible, but it is done with IVF, and is called preimplantation genetic diagnosis (PGD) -- exclusion. You would need a blood sample from both of you and from one or both of his parents, if they are alive. Basically what they do is trace which chromosome 4 has been passed onto the embryos from your side and from his side, and any that have the chromosome 4 from his parent with HD (or the side that has the HD in his family) they would not use for the pregnancy. They don't know for sure if that chromosome 4 actually has the HD gene on it, but it is regarded as 'suspicious' because it comes from the HD side. It is a bit hard to explain but it can be done so that no one knows if he has the HD gene or not. If you want more information about this type of testing you could go to the website
