A 65-year-old German Annegret Raunigk is set to become the oldest woman ever to give birth to quadruplets.
German Annegret Raunigk, already has 13 children, and her remarkable story will be featured in a TV documentary.
Her latest pregnancy was the result of artificial insemination using both donated sperm and eggs.
Ms Raunigk, who is in the 21st week of her pregnancy, said she was ''shocked'' when an ultrasound scan showed she was carrying quadruplets.
Her gynaecologist initially mentioned the possibility of a 'selective reduction', where one or more fetuses is aborted in a multi-fetal pregnancy, but she declined.
