For some couples surrogacy is their only chance to having a child. Each year hundreds of Americans go to India for the service.
According to CBS News, though the surrogacy business is booming in India it is however unregulated.

They have had no education and so there's a risk that some clinics could abuse them in this very lucrative industry.
