It is an advanced IVF treatment with a better chance of fertilisation. A single live sperm is directly injected into the egg through the eggshell and fertilised in a lab. The fertilised embryo is transferred to the womb. It is an effective treatment when men have infertility due to very low sperm count or no sperm at all; in which case we retrieve sperms from their testes or epididymis.
The success rate after transferring the embryo is the same as that of IVF treatment.
