From the southern state of Andhra Pradesh, Mangayamma was impregnated through IVF after she and her 80-year-old husband could not conceive naturally during their more than 55 years of marriage, according to CNN.

"The surgery went well ... the mother and the babies are all healthy with no complications," Dr. Sanakayyala Umashankar, who conducted the C-section because of Mangayamma's age, told CNN.

The mother will be watched over by doctors for the next 21 days.
