Intracytoplasmic Sperm Injection (ICSI)

What is Intracytoplasmic Sperm Injection (ICSI)?

Intracytoplasmic Sperm Injection (ICSI) is a procedure which is done either in accordance with IVF or if IVF does not work. The key difference between IVF and ICSI is how the sperm fertilizes the egg. As the name suggests, in Intracytoplasmic Sperm Injection, a single sperm is directly injected into the egg to maximise the chances of fertilisation.

• The healthiest and most potent sperm is chosen.
• In male factor infertility, ICSI has a greater chance of success than IVF.

A form of ICSI which uses high powered microscope to select sperm with the best visible morphology is a further step to maximise the chances of fertilisation. This is known as IMSI (Intracytoplasmic Morphologically Selected Sperm Injection)
