Surrogacy
Surrogacy means getting pregnant and carrying a child for other persons/person who will become the child's parents\parent after their birth. Some reasons why people may look for surrogacy is if a single man wants a child, pregnancy is too much of a risk, or if a woman can't 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, Japan, Germany and France 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.
