Intracytoplasmic morphologically selected sperm injection (IMSI) is a variation of ICSI that uses a higher-powered microscope to select sperm. This allows embryologists to look at the sperm in greater detail (including the nucleus which contains the sperm’s genetic material). The motile sperm organelle morphology examination allows the detection of sperm vacuoles that seems to be related to sperm DNA damage.
