ICSI treatment is widely known as Intracytoplasmic Sperm Injection. In this process, the fertilization of the egg is done by a tiny needle known as a micropipette. With the help of this needle, a single sperm is directly injected into the center shell of the egg. Later on, the embryo is developed by fertilization of the egg in a laboratory then it is transferred into the womb of a woman. It is one of the effective methods for fertilization outside the body.
