In vitro fertilisation (IVF) is one of several techniques available to help people with fertility problems have a baby.
During IVF, an egg is removed from the woman's ovaries and fertilised with sperm in a laboratory.
The fertilised egg, called an embryo, is then returned to the woman's womb to grow and develop.
It can be carried out using your eggs and your partner's sperm, or eggs and sperm from donors.
