IMSI is the acronym of Intracytoplasmic Morphologically Selecetd sperm injection . IMSI is the laboratory technique being used in the laboratory for the IVF treatment involving the process of insertion of the sperms into the egg to enhance the fertilization process. It uses high power magnification for the visualization of the sperm, allowing the experts to select the best sperm with high chances of fertility to be inserted into the eggs for a high degree of chances of pregnancy among couple to give a birth to a new life.
The Intra Cytoplasmic Sperm Injection selected, better known as IMSI for its acronym in English (Intracytoplasmic morphologically-selected sperm injection) is a laboratory technique used in IVF treatments (IVF) and involves inserting sperm into the egg.
IMSI is a real-time method where sperm is selected before the microinjection takes place. This is done using an inverted microscope that is able to provide much greater magnifying power (around 6000 times) than that normally used in reproductive laboratories (400 times) to carry out ICSI.
With this microscope, Biologists can see the internal morphology of sperm and discard those with abnormalities. Being able to select sperm without morphological alterations is believed to increase the chances of successful implantation of the pre-embryo and decrease the likelihood of miscarriage.
This technique still requires more study to demonstrate its efficacy and validity in order to be used routinely in the assisted reproduction laboratory and to be recommended with sufficient scientific evidence.
IMSI may improve the chances of fertilization in vitro and can be used if you have performed several unsuccessful In Vitro Fertilization attempts.
