A French couple who were both conceived using sperm donation have confirmed through genetic testing that they are not biologically related.
Audrey and Arthur Kermalvezen met at a gathering of donor-conceived activists in 2010. At the time, France had only two sperm banks and many donors had made multiple donations, meaning they could not rule out sharing a biological father. However, French law prohibits people from taking DNA tests at home.
The couple eventually obtained a genetic test through a doctor, which indicated that they were not related. They later took a home DNA test despite the legal restrictions, which confirmed the result.
