IMSI, short for intracytoplasmic morphologically selected sperm injection, is a variation of the ICSI technique. It allows the embryologist to utilize a microscope with significantly high magnification to analyze the morphology of sperm closely, providing a more comprehensive evaluation.

IMSI may require an additional two to three hours of sperm examination to identify the most suitable and genetically promising ones for injection into the available eggs.

Studies comparing the two techniques, ICSI and IMSI, found no significant disparity in fertilization rates. However, couples who underwent IMSI experienced higher rates of pregnancy and lower rates of miscarriage compared to couples who opted for ICSI.

In our clinic, we offer IMSI to couples with male factor infertility with excellent results.
