It is measured by the reproductive potential of the man. It encompasses the testicle’s ability to produce quality sperm capable of fertilizing the egg and the man’s ability to copulate.
IMSI is based on the technical developments of the microinjection procedure known as “ICSI”. Within IMSI, sperm selection is carried out through further evaluation of their appropriate morphology, since it is possible to observe them with a 6,300 magnifications facing the 400 magnifications of common ICSI. Therefore, certain microstructural aspects of sperm which may go unnoticed for the embryologist’s eye can be displayed in detail.
