ICSI Treatment

ICSI is used when the male partners’ sperm is suboptimal, when previous standard IVF treatment has been associated with a low fertilisation rate and occasionally used if only a few eggs are available. With ICSI a single motile sperm is isolated from the male partner’s semen sample and the tail of the sperm is cut to immobilise the sperm. The sperm is aspirated into a very fine glass needle (about one tenth of the diameter of a human hair at its tip).

The sperm is then injected directly into the centre of the egg and the needle withdrawn. A very small percentage of eggs can be damaged by the injection procedure but this is more than offset by the increased fertilisation rate.
