An IVF blunder that denied a couple the chance of another baby has led to calls for an increase in the number of treatment cycles available on the NHS in Wales.

The couple, from Bridgend, South Wales, have been compensated by their NHS trust after their last embryo was implanted in the wrong woman by mistake.

The woman who received the embryo at the IVF Wales clinic, in Cardiff, chose to have a termination after finding out what had happened.

Currently, suitable couples can have one cycle of IVF treatment, despite advice from the National Institute for Health and Clinical Excellence that they should receive three.

Conservative assembly member Darren Millar, chairman of the Welsh Assembly’s cross party health, wellbeing and local government committee, said: “I want it to be in accordance with the NICE guidance and the NICE guidance indicates that there should be up to three courses of treatment.”

But an assembly government spokesman said that while it recognised the rationale for more than one cycle, the assembly was constrained by the the budgetary position of the NHS in Wales.

The regulation of human fertilisation and embryology has not been devolved to Cardiff.
