ICSI

Intracytoplasmic Sperm Injection – ICSI

What Is ICSI?

ICSI is a very effective method to fertilize eggs in the IVF lab after they have been aspirated from the female. With the use of specialized micromanipulation tools and equipment including a specialized microscope, the embryologist is able to pick up an individual sperm in a specially designed ICSI needle.

The needle is then carefully advanced through the outer shell of the egg and egg membrane. The sperm is then injected into the inner part of the egg. This results in the normal fertilization in about 75% to 85% of eggs.

The most common reasons for using this method of fertilization is in cases with severe male factor infertility, previous IVF with no fertilization of the eggs or a female with low egg yield at retrieval.
