The IMSI method was first developed in 2004 by a team led by Benjamin Bartoov, of Barilan University in Israel, who used IMSI to select those sperms with a shape and size that indicated good genetic quality. The pregnancy rate in patients jumped from 30% to 66%.
It Is a new breakthrough for treating male infertility. It is a new microscope machine that will allow infertility specialists to select the best quality sperm which satisfy all parameters and use it for specialized test-tube baby procedure of ICSI.
This microscope will help to magnify the sperm 7,200 times, in actual it is the advanced version of of the earlier technique of Intracytoplasmic Sperm Injection (ICSI), having the magnification capacity of 16 times higher than ICSI.
IMSI is said to be more beneficial than ICSI as it improves the success rate among men with the worst prognosis and for the couples who have unexplained infertility. Also it was found that egg fertilized with the help of IMSI p-rocedure resulted into better quality embryo as well as better rate of blastocyst formation and therefore better pregnancy rates.
