Intracytoplasmic sperm injection (ICSI) is a lab technique used within an IVF cycle. Instead of leaving eggs and sperm together in a dish, our embryologist selects a single healthy sperm and injects it directly into each mature egg under a high-powered microscope.
When we recommend ICSI
- Low sperm count, poor motility or abnormal shape
- Sperm retrieved surgically
- Fertilisation failed or was low in a previous IVF cycle
- Using frozen eggs
For you, an ICSI cycle feels exactly like IVF. The difference happens in the lab on the day of egg retrieval.
