Physiological Intra-Cytoplasmic Sperm Injection (PICSI)

PICSI is one method of sperm selection. This method uses natural substances that bind mature sperm to each other. At first glance, healthy-looking sperm may actually be immature. With hyaluronic acid, mature sperm can be separated from immature sperm. Mature sperm have a functional receptor on the head that is a prerequisite for successful fertilization. Only those sperm that can attach to hyaluronic acid are suitable for fertilization.
