Depending on your situation, CRE offers many other services that may be used with IVF-ET.
This procedure uses microscopic instruments to enhance the chances of egg fertilization and implantation of the embryo. This is used on patients who have a low sperm count, non-moving sperm or abnormally shaped sperm. There are two approaches:
Intracytoplasmic Sperm Injection (ICSI)
This is done in the laboratory. It involves injecting a single sperm into an egg so that the sperm doesn’t have to swim through the reproductive tract to reach and penetrate the egg.
This involves thinning the outer covering of the embryo so that it can expand and implant in the uterine lining.
Microsurgical Epididymal Sperm Aspiration (MESA)
This outpatient procedure involves extracting sperm from the epididymis, where developing sperm are stored. This is used for congenital problems, a vasectomy, neurological problems or inability to ejaculate. These sperm can be used in IVF-ET procedures. The sperm are put in direct contact with the egg or are injected into the egg using ICSI.
