Doctors at the fertility clinic say at first they also worried about the couples' age, but eventually agreed to go through with the treatment.
"I first tried to avoid the case because she looked very frail. Then we made her undergo all the tests and once all the results were okay we went ahead,"said Dr. Anurag Bishnoi, who runs the fertility clinic.
The couple says despite what others may say, they are thrilled to finally have their own child.
