Eggs need to be fertilised with sperm during IVF (in vitro fertilisation). This usually occurs in the laboratory. The eggs are checked after approximately 20 hours to see if any have been fertilised. Sperm is injected directly into the egg using a micromanipulator if the sperm are slow or weak. A human egg (ovum) is approximately 0.1mm in diameter. This means precise coordination and a microscope are needed.
