Surrogacy means getting pregnant and carrying a child for another group of parents or for other women if they're unable to have children through their own pregnancy. The carrier of the children is called a surrogate mother. It may or may not involve monetary arrangements between the surrogate and the biological parents. In some countries like China and Japan it is considered illegal. In Australia and New Zealand commercial surrogacy is an offence. India is the main destination for this as surrogacy here is cheaper.
