IMSI-Intracytoplasmic Morphologically Selected Sperm Injection.

What is IMSI?

  • IMSI stands for Intracytoplasmic Morphologically Selected Sperm Injection.
  • The IMSI process requires the evaluation of sperm, at very powerful magnification, utilizing an inverted microscope.
  • The digitally enhanced lens presents a much greater magnifying power compared to the one usually used in ICSI.
  • This highly-magnified view enables us to identify subtle sperm defects that are not visible with a conventional ICSI microscope.
  • The embryologists examine defects within the sperm as well as checks for more familiar shape, size, and motility abnormalities.
  • Once selected, the sperm is introduced into the egg in the same way as with the standard ICSI procedure.

Who needs IMSI?

The following patients can benefit from IMSI:

  • The men with elevated levels of DNA fragmentation.
  • When there have been reoccurring miscarriages.
  • Where implantation hasn’t worked on several occasions following the ICSI treatment.
  • Where preceding, embryos have developed unsuccessfully.
  • Male factor infertility – a high number of abnormal sperm.
