It can be a suitable treatment when sperm quantity or quality is so poor that conventional IVF would lead to low or no fertilisation. For the woman, the treatment protocols, egg collection and embryo transfer techniques are the same as for IVF.
The only difference occurs in the laboratory after egg collection when, rather than allowing the egg and sperm to interact in the dish, a single sperm is injected into the centre of each egg using a micro-injection needle.
