An advanced modification of the ICSI technique, IMSI treatment examines the sperm samples under a microscope that is almost 6000x more persuasive to evaluate their "morphology" more effectively. The embryologist can see relatively small deformities in the sperm head that aren't noticeable with standard ICSI at a higher magnification. Although it is yet to be proved to be of benefit for all involving sperm injection, it is recommended in those with a history of repetitive implantation failures, repeated ICSI failures or severe teratozoospermia (abnormal sperm shape).
Intracytoplasmic Morphologically Selected Sperm Injection (IMSI) is a sperm infusion (ICSI) of an exceptionally chosen single sperm straightforwardly into the full-grown egg. IMSI is a new and moderately unstudied strategy. Sperm have formed heads and frequently have vacuoles (holes) and it is accepted that these strange sperm are less inclined to convey typical hereditary elements. IMSI Treatment utilizes high force amplification to distinguish these irregularities of sperm, thus selecting the most typical looking sperm. Since sperm are so minuscule contrasted with the egg, exceptional high force amplification is required. With the advanced procedure of IMSI Treatment, high-quality sperms are detected for final fertilization.
