Physiological Intracytoplasmic Sperm Injection (PICSI)

PICSI is a method for selecting sperm for intracytoplasmic sperm injection (ICSI). It allows the embryologist to pick a fertile spermatozoon in the same way as nature does. The hyaluronan, a biopolymer in the gel layer surrounding the oocyte, is responsible for this. To facilitate penetration into the egg, we coat the sperm with Hyaluronic acid. PICSI detects sperm that can attach to Hyaluronan hydrogel in the dish. These ideal sperm are then chosen for therapy and used for ICSI.
