Mauro (R) and his partner Juan Carlos from Spain hold their twin babies at a private hospital after an Indian surrogate mother delivered twin baby girls for them in New Delhi February 16, 2011. Surrogate motherhood is among the latest in a long list of roles being outsourced to India, where rent-a-womb services are far cheaper than in the West. Fertility clinics usually charge $2,000-$3,000 for the procedure while a surrogate is paid anything between $3,000 and $6,000, a fortune in a country with an annual per capita income of around $500. But the practice is not without its critics in India with some calling it the "commoditisation of motherhood" and an exploitation of the poor by the rich.
