Sperm donor with cancer gene fathers 197 children
December 10, 2025
A sperm donor with a genetic mutation that increases cancer risk has fathered at least 197 children across Europe, including in Cyprus. This mutation affects the TP53 gene, which is vital for preventing cancer. Children born from this donor face a high risk of developing cancer throughout their lives. The European Sperm Bank, which managed the donations, expressed condolences to the affected families. Doctors have raised concerns about the health of these children and emphasized the need for regular medical monitoring.
