Investigations by Danish broadcaster DR reveal a Danish man, a former SS volunteer, secretly donated sperm in Sweden during the 1960s. This resulted in the birth of at least 15 children, unaware of their donor’s background. The man reportedly concealed his past when providing donations at a Swedish fertility clinic. Authorities are now grappling with the ethical implications and notifying those affected. This case raises questions about screening procedures for sperm donors during that era and the right of children to know their genetic origins. Families impacted are expressing shock and seeking answers about their heritage. The Swedish National Board of Health and Welfare is reviewing the historical practices of fertility clinics.
