Is IMSI right for me?

Sperm quality and mobility is just as important to a successful IVF cycle as the egg. Fortunately, there are now a wide variety of techniques available to help support your dream of parenthood – and one of them is IMSI. Although it doesn’t increase the fertilisation rate using an Intra-Cytoplasmic Sperm Injection (ICSI) or the outcome, it can help lower the chance of a miscarriage caused by a genetic problem.

Who’s it for

You might want to have IMSI if…

  • You’ve had more than two failed ICSI cycles not related to egg quality
  • You have a history of miscarriage
  • You have a high number of abnormal forms
  • You produce poor quality embryos not related to egg quality
