We want to give your child the best possible start. Believe me, we have enough imperfection built in already. Your child doesn't need any more additional burdens. Keep in mind, this child is still you...simply the best of you. You could conceive naturally a thousand times and never get such a result. A British couple have used an enhanced in vitro fertilization procedure to become pregnant with a child guaranteed not to develop the breast cancer that has decimated the female relatives of the man's family. They were advised that children conceived naturally would have a 50-75% likelihood of developing the same breast cancer. Of eleven embryos successfully fertilized in the lab, five were identified that lacked the genetic marker for the disease, and two were implanted into the woman's uterus. The subject of eugenics is always a sticky wicket in public discussions. Personally, I'm in favor of such procedures and would like to see more research efforts focused along these avenues. As one of the fundamental goals of scientific medicine is the improvement of the human condition, this strikes me as the ultimate form of preventive care. It will be interesting to see how this is accepted and backed in terms of research time and money, as it flies directly in the face of the western pharmaceutical industry's traditional approach to treating the symptoms (at enormous and ongoing costs to patients) rather than eliminating root causes.
