One fertility expert at the London Fertility Clinic revealed that: "many women were willing to use black surrogates because there was a lesser chance of the host becoming attached to a child of a different color".

He noted that surrogacy has become a booming business as some couples pay up between £100,000 to £150,000, including additional £25,000 for the surrogate to carry the child.
