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.
