In-vitro fertilisation (IVF) is a type of assisted reproductive technology (ART) where sperm and an egg are fertilised outside of the human body. IVF is a complex process that involves retrieving eggs from ovaries and manually combining them with sperm in a lab for fertilisation. Several days after fertilisation, the fertilized egg (now called an embryo) is placed inside a uterus. Pregnancy occurs when this embryo implants itself into the uterine wall. A successful pregnancy can be confirmed about two weeks later.
