In vitro fertilisation is the procedure of fertilising an egg outside of the body in a laboratory.
The fertilised egg may then be implanted into a living womb, frozen and stored for later use, or used for experimentation or the creation of embryonic stem cells. Different countries have different legislations about such procedures.
