Intracytoplasmic morphologically selected sperm injection (IMSI)

IMSI stands for intracytoplasmic morphologically selected sperm injection. IMSI is a process that uses high magnification optics (up to 6000X magnification) to select the best sperm for injection – the most morphologically normal sperm. IMSI is indicated for couples where the male partner has significant known sperm morphology problems and possibly for couples who have experienced recurrent unexplained implantation failure or miscarriage.
