Intracytoplasmic Sperm Injection (ICSI)

Intracytoplasmic Sperm Injection (ICSI)

ICSI is when a single, healthy sperm is injected into each egg during the IVF Laboratory stage rather than just placing the sperm in a dish with the eggs.

For eggs to be successfully fertilised in IVF, at least 100,000 motile sperm need to be present in each petri dish with the egg. So, for men with low sperm count, low motility or other quality issues, IVF would not lead to a good chance of the eggs being fertilised. In these cases we may recommend ICSI.

We may also recommend ICSI if you have unexplained infertility, or when there has been low fertilisation in previous IVF cycles. It’s also used if DNA fragmentation levels in sperm are high.

In men with low sperm count, low motility or other quality issues, IVF would not lead to a good chance of the eggs being fertilised. In these cases ICSI is recommended. This is when a single healthy normal looking sperm is injected into each egg.
