The Human Fertilisation and Embryology Authority (HFEA) has advised that since October 2007 it has only collected data where a congenital abnormality was reported as either observed or uncertain following a birth event. The HFEA has also advised that it does not collect information on the incidence of autism or other neurological disorders in births or pregnancies resulting from the use of frozen oocytes after thawing and fertilisation.
