Thanks ladies. Yes - men are certainly wired differently to us aren't they? Yet when I asked him why he was so deadset against one last one he just said I don't have enough patience with the 3 we've already got. To me that is not really a decent enough reason. I have even offered him my full support for a vasectomy after this try if he will agree to it, so we'll see what happens. In the meantime I will just start taking my folic acid in high amounts, prenatal and Coq10 and pray for a miracle. :)
