The screening of in vitro embryos resulting from in vitro fertilization (IVF) treatment for chromosomal abnormalities (aneuploidies) has as a primary aim to help patients achieve a successful pregnancy. Most IVF centers will not transfer aneuploid embryos, as they have an enhanced risk of leading to implantation failure and miscarriage. However, some aneuploidies, such as trisomy-21, can lead to viable pregnancies and to children with a variable health prognosis, and some prospective parents may request transfer of such embryos. I present two cases where the testing for and detection of trisomy-21 can lead to conflicts between IVF professionals and patients and argue that in most such cases respect for choices of patients should prevail.
