Microjection, also called intracytoplasmic sperm injection (ICSI), implies injecting a single selected sperm into the egg. An enzyme is used to remove cells that surround the egg before the procedure. Microinjection uses micropipettes that are attached to special microscopes. ICIS has been used since 1992 and fertility rates have increased up to 80 to 90 percent.
