Since everyone else here has focused their attention on laws in India, and included some very insulting and offensive definitions, let me answer your question from the perspective of someone that's actually done it!
Primarily, let me first confirm that I’ve carried 5 babies as a surrogate and I’ve never been to India, so surrogacy does actually happen in other places besides India. I’ve carried for European Caucasians, Canadian Jews, a Canadian man of European stock and Canadian-born Caucasians, in that order. Not one was Indian, so other people besides Indians do access surrogacy.
But you asked for a definition, and I’ll use very simple terms, and rather than bend your ear with a lengthy discourse on Indian laws, I’ll simply provide a definition.
There are 2 types of surrogacy, called Traditional Surrogacy and Gestational Surrogacy.
Traditional Surrogacy is where the pregnant woman has provided her own ova for the creation of the pregnancy and has been inseminated by a doctor or using an at-home method (I do not endorse the at-home method) and very rarely, through intercourse.
Gestational Surrogacy is where the pregnant woman is carrying a baby to which she has no genetic relationship. The baby was created with an ova that came from another woman other than the surrogate. It may have been a donated ova or come from the intended mother, but it is definitely not the surrogate’s. A gestational surrogacy can only be created and achieved with the help of a clinic, a doctor and trained medical staff.
In both versions of Surrogacy, the pregnant woman will not raise the baby.

Let's see how surrogacy inspires hope in single parent, infertile couple etc to have child(ren) and changed their life forever.Continue... andrewspradlin.weebly.com/
