In vitro fertilisation (IVF) is a process where eggs are fertilized by sperm outside of the body in a laboratory. The fertilized egg is then transferred to the patient's uterus in an attempt to establish a pregnancy. The first successful IVF birth was Louise Brown in 1978. IVF involves stimulating a woman's ovaries to develop multiple eggs, retrieving the eggs, fertilizing them with sperm, and transferring the resulting embryo into the uterus if development is successful.
