Indian couple Erramatti Mangayamma, 73, and Raja Rao, 80, made headlines on Sept. 5, when Mangayamma, a farmer from the southern state of Andhra Pradesh, became pregnant through IVF and gave birth to the babies via caesarian section. The couple had been married since 1962 but had had difficulty conceiving naturally.
"The surgery went well ... the mother and the babies are all healthy with no complications," Dr. Sanakayyala Umashankar, who performed the surgery, told CNN at the time.
Yet, just a day after the announcement, Rao reportedly collapsed from a heart attack and was taken into intensive care. Since giving birth, Mangayamma has also been in intensive care, though it is unclear why.
The girls' births have also sparked a heated debate over the ethics of letting a septuagenarian — a person between 70 and 79 years of age — undergo IVF treatment, the Telegraph notes. Umashankar denied claims that he was trying to break any records and has since accused Mangayamma of lying about her age.

NANTES, FRANCE - MARCH 23: Staff work in a hospital on March 23, 2011 in Nantes, France. The center of medically assisted procreation Hospital of Nantes is the first center in France to benefit from renting an Embryoscope for conducting an international collaborative study. The Embryoscope consists of an incubator to receive the embryo; in the incubator a microscope is installed to continuously visualize the development of the embryo on the computer screen. Instead of leaving the embryo in the incubator for observation under the microscope as it is today, this very high-tech equipment meets all the conditions necessary for its cultivation by guaranteeing a stable environment. Embryoscope is developed by the Danish company Unisense Fertilitech and should improve the chances of success of IVF. The center of medically assisted procreation from Nantes hospital performs each year about 1,100 attempts at in vitro fertilization, which places it among the top ten French centers.
