Intracytoplasmic sperm injection (ICSI) is performed as part of your in vitro fertilization (IVF) procedure if medically indicated. It is a process in which an embryologist injects a single sperm into the cytoplasm (center) 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 physician can transfer it into your uterus.
Your physician may recommend ICSI as part of your IVF procedure to treat many causes of infertility, especially when there is a problem with the sperm, such as low motility (movement) or a low sperm count. ICSI is especially useful in cases where the sperm cannot penetrate the egg or if the sperm is abnormally shaped. This treatment has been revolutionary in treating male factor infertility cases.
