ICSI is a technique of assisted reproduction similar to IVF conventional, with the difference that the insemination of the eggs is done by introducing a sperm into the egg using a microneedle, directly and therefore much more elaborate than in IVF. The greater technical complexity implies a higher cost of the ICSI technique.
