IVF treatment. Technician using a light microscope to inject human sperm into a human egg cell (ovum) during in vitro fertilisation (IVF). This technique is known as intracytoplasmic sperm injection (ICSI). IVF is performed when a couple want children but cannot conceive naturally. Usually several fertilised eggs are implanted in the woman's uterine lining to improve the chances of success.
