Why does UK DonorLink use DNA testing?
DNA testing is used because there is insufficient or little information available from clinics or other records to make links between those who may be genetically related. Prior to the Human Fertilisation and Embryology Act 1990, fertility clinics were not regulated by law. Donations were usually anonymous and in some cases records were not kept or were lost when a clinic closed. There were a mix of private, NHS and charitable clinics involved in fertility treatment. Sperm donations started to be routinely frozen from the early 1980’s onwards rather than only being used fresh. Some donations were transported to other parts of the country to be used in treatments away from where the donation was made. It is not known how many donors or patients used each clinic. Some donors donated at several clinics at the same or different times. For those who donated or were conceived prior to 1980, information such as the name of a clinic, doctor and year of conception can provide useful background
