Intracytoplasmic sperm injection (ICSI) is performed as part of in vitro fertilization (IVF) procedure. It is a process in which an embryologist injects a single sperm into the cytoplasm (centre) of each egg. After the embryologist fertilizes the egg with the sperm, he or she will observe the egg over the next day or so. If fertilization occurs and the embryo matures properly, a doctor can transfer it into uterus. ICSI is performed by gynecologists.
