ICSI

Intra Cytoplasmic Sperm Injection

The availability of this Intra-Cytoplasmic Sperm Injection, “ICSI” technique (which was developed and perfected by the Brussels University and our institution in St. Louis) means that men whose sperm previously were too weak or too few to fertilize in vitro (IVF), now have no problem fertilizing the eggs.

The fertilization rate per egg using ICSI is about 70% even when lower quality sperm is used, the fertilization rate per infertile couple is over 99% if the wife has adequate eggs, and the pregnancy rate per treatment cycle is over 50%. This is not significantly different from regular IVF with normal sperm. This technique is very cost-effective.

This procedure is very similar to IVF except that the sperm are introduced directly into the egg and is used alongside IVF. This method is usually only used in cases where the male has low quality or quantity of sperm.
