What is the oldest age at which it is safe to be a mother?

Becoming Pregnant: Medicine does not answer this question in the way you ask. Until a female is no longer fertile (has gone into menopause) she is able to become pregnant. After aged 35 i believe that is when some of the genetics problems in some percent of pregnancies begin to increase.

Record: The world's oldest mother gave birth to twins at age 70. She suffered complications from her C-section and died 18 months later, was too weak to recover. The next oldest was 68 when she gave birth. I would suggest that you have your children in your 20s and 30s.
