IMSI: the new improved application of ICSI

The development in ICSI, in combination with the improvement of microscopes’ optical systems, enables the effective detection of viable spermatozoa. Recent studies and new technology in optical microscopy systems together with our laboratory experience in Embryolab confirm that the combination of the ICSI and IMSI methods improves:

• the fertilisation rate,
• the proportion of embryos reaching the blastocyst stage, increasing the chance of pregnancy, while decreasing the probability of miscarriage.

It is important to note that this method enables the selection of the healthiest spermatozoa, avoiding the use of sperm with defects, which are not visible to the lenses commonly used in conventional laboratories.


• Embryolab is one of the first laboratories in the world to have adopted this technology
• Our scientific team is highly experienced in the application of this method
