(msnbc) A Spanish woman believed to have become the world's oldest new mother when she gave birth at 66 has died at 69, leaving behind twin toddlers, newspapers reported Wednesday. Maria del Carmen Bousada, who reportedly died Saturday, gave birth in December 2006 as a single mother after getting in vitro fertilization treatment at a clinic in Los Angeles. The births ignited a firestorm of debate over how old is too old for a new mother, and how much responsibility fertility clinics have over who gets treatments. Bousada told an interviewer she lied to the fertility clinic about her age, and maintained that because her mother had lived to be 101, she had a good chance of living long enough to raise a child.
