Intracytoplasmic Sperm Injection (ICSI) is a technique that has been developed to maximise the chance of fertilisation. The procedure involves injecting a single sperm into the centre of each oocyte (egg).
During ICSI, the sperm doesn’t have to travel to the egg or penetrate its cumulus cells or outer layers. Instead, our scientists use sperm microinjection to inject a single sperm directly into the cytoplasm of the egg.
At the clinic, we use a medium called Sperm Slow™ during sperm selection. This medium contains hyaluronan (HA), which binds sperm that are more likely to have normal DNA and thus allows selection of these bound sperm for injection. By selecting the sperm that are bound to HA and using them for ICSI, the embryologists are preferentially using the better-quality, more mature sperm. This technique is also known as PICSI and we use it as standard practice with no additional cost to the patient.
The treated eggs are checked the day after the ICSI procedure to see if fertilisation has occurred.

For the egg: as ICSI is more invasive and requires more handling than standard IVF insemination techniques, there is a small chance (less than 5%) that the egg may be damaged during the procedure – resulting in a non-viable egg.
People contemplating fertility treatment should be aware of the possible risks, some of which are comparable to those of elective surgery. We encourage you to discuss these with your treating specialist.
