What would you consider the ultimate selfless act? Louise, 38, and her husband James, 36, are giving a childless couple a true gift - a baby.
After five unsuccessful surrogate pregnancies in four years, Louise is due to give birth to another couple's baby in March. Louise and James say having a family is something they have been lucky to experience with their own biological children, and they can't wait to see the look on the intended parents' faces.
Despite the disappointments and setbacks, they have created a legacy and say they have no regrets on their surrogacy journey.
Commercial surrogacy is illegal in the UK, and so potential surrogates can only receive expenses
Those lucky enough to be chosen by a surrogate face an estimated bill of £25,000. This includes IVF treatment (around £7,000 a cycle) all private medical bills for their surrogate, travel and accommodation expenses, maternity pay, life insurance and maternity clothes.
The first known case in the UK was in 1985 and since then it is estimated that around 900 children have been born as a result of surrogacy
>There are approximately 50 surrogate children delivered in England and Wales each year
If the surrogate mother decided she wanted to keep the child, the intended parents would have to make an application through the court for custody of the child. The court would determine the outcome.
