Couples desperate for children are turning to India, where relaxed laws on surrogacy means the business in babies is booming. Here a womb can be rented for a few thousand pounds and IVF treatment is a fraction of what it costs in the West. "My criteria is very strict," Dr Anup Gupta tells me in the midst of a packed waiting room in New Delhi. "The surrogate must be healthy and she must already have a family with at least one or two children of her own, minimum. "She must NOT be doing this primarily for financial reasons but because she wants to help another family." Dr Gupta says he gets about 15 patients from abroad every month looking for a surrogate. Most of the time he uses eggs and sperm harvested from the couple and then implants the embryo into the surrogate mother. The couple then pay all her medical expenses plus lump sums in stages. By the time a baby is born the woman who has effectively rented out her womb stands to make around 3.5 lakh Indian rupees or around £4,600. Bobby and Nikki Baines from Ilford in east London spent nearly a decade and £70,000 on IVT trying to conceive before advertising in an Indian paper and finding a woman who was prepared to carry their child. Now they have a baby daughter called Daisy.
