In 2003 Dr Nayana Patel, who ran her own fertility clinic in the state of Gujarat in India, carried out her first surrogacy procedure. It was a purely altruistic case and involved a surrogate mother and her own daughter. Dr Patel's clinic would go on to become one of the biggest in India attracting Western couples in a country where women were paid to become surrogates. It was legalised in 2002 but due to growing criticism, the government banned couples from the West from paying Indian surrogates to bear their children in 2015, arguing that the industry was exploiting poor women.
