IVF cell injection
Description
IVF procedure. IVF (in vitro fertilisation) is the fertilisation of an egg cell (centre) outside the human body. The technique depicted here is called intracytoplasmic sperm injection (ICSI), where a single sperm cell is injected directly into the egg using a micro-needle (right). The fertilised egg is then cultured for a few days before being introduced into the mother's uterus. IVF is used to help infertile couples have children.
