The article in the Sunday Times last week ‘Embryos destroyed for minor disorders’ was inaccurate and misleading and could cause confusion and distress for those families undergoing or considering IVF treatment with pre-implantation genetic diagnosis (PGD). PGD is licensed only for serious medical conditions which severely threaten the future health and wellbeing of children. It is not a ‘routine’ procedure. In 2007, out of nearly 37,000 patients who received fertility treatment, 169 had PGD, fewer than one in 200. Embryos are tested when they are just three days old and made up of about eight cells. They are not at the developed stage of the foetus as shown in the photograph.Finally, to suggest that embryos are destroyed for ‘minor conditions’ which would require ‘unpleasant treatment’ is not only misleading, it is disrespectful both to those living with the condition, and those seeking to avoid passing on these serious conditions to their children.
