For many couples, the only hope to create a child of their own is to fertilize an egg in a test-tube and implant it in a surrogate.
Indian clinics do that for a fraction of the usual cost.
The procedure in which doctors implant an embryo into the womb of a surrogate mother is a delicate operation.
If all goes well, in nine months time, the surrogate will deliver a baby for a childless couple.
But the country's baby business has critics, like Dr. Ranjana Kumari.
According to CBS News, Dr. Kumari argues that there so many Indian women who want to do this because the country has so many poor women.
There are so many women who don't want to see their own child dying out of bad health, or not getting educated, not getting two meals a day. So that's why so many women are available, she added.
Dr. Ranjana Kumari pointed out that the industry needs to be regulated.
According to the report, the stressed that the vulnerability of poverty is being exploited in this whole system, and it should be banned.
The report pointed out that there are some clinics in India that give the surrogate mothers life insurance and medical care, even after the baby is born.
But other clinics don't provide this care. Their primary concern is the baby because that's where they make their money.
