ICSI (Intra Cytoplasmic Sperm Injection):-

ICSI, is Intra Cytoplasmic Sperm Injection. ICSI is used as advanced part of an IVF treatment.

In normal IVF, many sperm are placed together with an egg, in hope that one of the sperm will enter and fertilize the egg.

With ICSI, the embryologist takes a single sperm and injects it directly into an egg.

What is the Success Rate for ICSI?

The ICSI procedure fertilizes 50% to 80% of eggs. (Interestingly, just because a sperm is injected into an egg, it does not guarantee fertilization will happen.) Even if fertilization takes place, the embryo may stop growing. However, once fertilization happens, the success rate for a couple using ICSI with IVF is the same as a couple doing regular IVF treatment.

Indications for ICSI are same as IVF, but it is more required in severe male factor infertility.
