[8] DNA testing is rarely carried out to confirm claims of maternity at advanced ages, but in one large study, among 12,549 African and Middle Eastern immigrant mothers, confirmed by DNA testing, only two mothers were found to be older than fifty; the oldest mother being 52.1 years at conception (and the youngest mother 10.7 years old).
