In a globalised world where everything at home is becoming more costly, outsourcing your needs to a third party thousands of miles away for less money makes a lot of sense.

For a country like India, one of the top global destinations for outsourcing, the benefits are tremendous – creating millions of jobs in sectors ranging from garment, software and car manufacturing to call centres and back office operations.

But over the last decade, a more controversial sector for outsourcing has emerged in India: pregnancy and childbirth.

With infertility rates on the rise and a growing acceptance of same-sex couples, thousands of people annually are opting for surrogacy as a way of having genetic children through a process of in vitro fertilisation (IVF) and embryo transfer.

With commercial surrogacy banned in most nations, many are flocking to India – a country free of regulation and with top medical professionals and low costs – to hire the wombs of women in what is known as “surrogacy tourism”.
