Intracytoplasmic Sperm Injection, ICSI for male infertility
Intracytoplasmic sperm injection, ICSI- is an injection procedure to help fertilize the egg. To fertilize an egg, the sperm must attach to the outside of the egg and then move through the layer called the zona pellucida to the inside of the egg. When the sperm can’t penetrate the outer layer, intracytoplasmic sperm injection can help by injecting the sperm directly into the egg.
Who needs intracytoplasmic sperm injection?
ICSI is most often a treatment for male fertility issues. Those fertility issues can be the result of not producing enough sperm, sperm that is not shaped correctly or does not move normally, sperm that has trouble attaching to an egg, or a blockage in the reproductive tract that may keep the sperm from getting to the egg. If there are very few eggs to be fertilized, often ICSI will also be used. In the case of preimplantation genetic screening -PGS-, ICSI is used to help ensure a good biopsy specimen without contamination of other sperm in the specimen.
Intracytoplasmic sperm injection is successful in fertilizing approximately 90 percent of eggs. However, in cases where criteria are not met for the indication of ICSI, standard insemination may have better results. It is possible, though rare, for babies conceived by ICSI to be born with a birth defect or an increased risk of infertility themselves. Though these risks appear to be due to the nature of the infertility, not the fertility treatment itself.
