ICSI | IMSI
Intracytoplasmic Sperm Injection (ICSI) and Intracytoplasmic Morphologically Selected Sperm Injection (IMSI) are names of procedures that involve injecting the sperm into the eggs.
Intracytoplasmic Sperm Injection (ICSI) is a type of IVF treatment where sperm is injected directly into the egg. This technique is used when the sperm is not optimal, whether this is due to low count, motility or morphology. It may also be performed in the presence of bacteria in the ejaculate or raised sperm antibody levels in the semen sample. This is the most commonly conducted procedure to address male subfertility.
Intracytoplasmic Morphologically Selected Sperm Injection (IMSI) is a relatively new technique used to assist sperm selection for fertilisation. This technique uses high power magnification to visualise the sperm, allowing specialists to pick sperm with the highest chance of achieving a successful fertilisation. This technique is particularly important in cases of repeated IVF failures, in those with history of miscarriages or in those with high sperm DNA fragmentation.
