The ICSI Procedure


The ICSI procedure is performed in the lab, after the egg collection. ICSI involves the injection of a single sperm into the fluid contents of the egg cell, called cytoplasm. A glass pipette, which is finer than a human hair, is used to collect a single sperm and inject it into the egg. The fertilised embryo(s) is then transferred to the women’s womb. Other than this element in the lab, your experience of treatment is the same as that of patients undergoing IVF.

Who is suitable for this treatment?


This treatment is particularly suitable for couples with a male factor infertility problem. This can be related to the density, morphology or mobility of sperm. The treatment can also be used where there is a suspicion that there may be an issue with fertilisation.
