The Human Fertilisation and Embryology Authority (HFEA) has advised me that between 1991 and 2004, 1,950,757 embryos were created, of which 78,505 were donated for research purposes. Data on embryos created for research is not routinely collected by the HFEA. However, information obtained by the HFEA from licensed centres suggests that approximately 370 embryos have been created for research purposes since 1991.
Data on the HFEA's register is currently being audited to improve the accuracy of the information available. It may, therefore, be subject to further amendment following completion of the modernisation programme in March 2006.
