Abstract
Selection of a live and morphologically normal spermatozoa is a fundamental stage in ICSI success because of its potential effects on early and late embryo development. In addition to the routine tests such as the spermogram and the spermocytogram, a number of tests have been developed for this purpose : the hyaluronic acid test, which measures the rate of DNA fragmentation using TUNEL (% of fragmented DNA) or electrophoresis separation of SPZ, SPZ evaluation using the FISH method, MSOME (motile sperm organelle morphology examination) techniques, et IMSI (intracytoplasmic morphologically selected sperm injection), which can evaluate the nuclear vacuoles, etc.
