'IMSI' High Magnification ICSI

When there is significant male infertility, the embryologist injects a sperm into each egg using a technique called ICSI. IMSI is a variation of ICSI using high magnification. ICSI can be useful for:

  • Men with poor sperm morphology. Poor morphology makes sperm more susceptible to oxidation damage
  • Men with a higher level of DNA fragmentation in their sperm. DNA fragmentation is a sign of oxidation damage
  • People with few embryos developing to the blastocyst stage 
  • People not pregnant despite the transfer of several reasonable quality embryos.
