Physiological Intracytoplasmic Injection of Preselected Sperm (PICSI)
Sperm selection method for ICSI, which is based on the evaluation of irregularities of the sperm surface membrane. Prior to ICSI itself, the sperms are layered over a microplate that resembles zona pellucida (the egg coat) with its composition. Subsequently, only the sperm that is firmly bound to the plate is used to fertilize the eggs. It is assumed that the sperms thus obtained is genetically healthier and should stand the highest chance of fertilizing the egg.
