Treatments for infertility - Intra-cytoplasmic sperm injection (ICSI)
A computer monitor showing intra-cytoplasmic sperm injection
ICSI can be used when:
- sperm counts are low
- mature sperm are abnormally shaped or don't move normally
- where sperm needs to be removed surgically
- frozen sperm that has reduced in quality is being used
A sample of sperm is collected and the head of the sperm is drawn into a needle and injected directly into the egg in order to increase chances of fertilisation.
