The Court determined that it is OK to check for serious genetic defects of embryos prior to implantation in couple with known serious genetic illnesses. In one of the cases the woman considering conceiving another child had already given birth to a disabled daughter, another woman went thru three failed pregnancies. It goes without saying that embryos that are non implanted after PID took place (ie after serious genetic defects have been diagnosed) will be destroyed.
Critics have trotted out the usual stuff like that this discriminates against the disabled, and that this takes us on a slippery slope to designer babies (ie selection in favor of blue eyed kids was mentioned). It is true that the court judgment takes a clear stance on the former issue. If at the embryonic stage it is possible to make a choice between a future seriously disabled child and a healthy (healthier) child, the latter is preferable and it is up to pregnant women to decline the implantation of the embryo known to be defective. On the latter issue, currently such choices would not be covered by the judgment, but frankly, what if someone chose blue eyes over brown eyes, or brown eyes over blue eyes, what danger would this really entail? If someone - like me - subscribes to the ethical stance (as I do) that women are very much entitled to make reproductive choices entailing abortions, for any reason or none, why should it matter that they decline the implantation of an embryo with the wrong eye color?
I do think my progressive friends need to think carefully about whether or not they support unconditionally a woman's right to make reproductive choices. If they do, the above mentioned slippery slope arguments must not faze them.
