IVF to the Rescue In every nation some babies begin life in a laboratory dish, as IVF overcomes blocked fallopian tubes, low sperm count, and other common fertility impediments. IVF now solves uncommon problems as well. In Kentucky, Avery Kennedy (left) began life via a donated frozen ovum, fertilized by Jared (shown here) and implanted in Wendy’s uterus. In Spain (right), a few hours after Roger’s conception, one stem cell was removed and tested for the gene for Huntington’s disease. Since one of his parents (shown here) has that dominant gene, a zygote had a 50/50 chance of inheriting it. Roger did not.
