Ten children conceived with the same sperm donor, who carried a rare genetic mutation linked to cancer, have been diagnosed with cancer, prompting calls for limits on the number of families per donor. The sperm bank confirmed the mutation was present in some of the donor's sperm and used by at least 67 families, raising concerns about genetic disease dissemination and the need for stricter regulations.
