ICSI (Intra Cytoplasmic Sperm Injection)

Sperm have several important functions, the most critical of which are capacitation and hyperactivation ( “swimming” to meet the egg), zona binding and acrosome reaction (penetrating the egg’s outer shell and inner membrane), and the ability to fertilize the egg (delivery of male DNA to the egg).

ICSI is a micro-manipulation technique in which a trained scientist carefully selects a single healthy sperm and gently injects it directly inside of the egg. ICSI can overcome many of the most severe sperm related problems that impair natural fertilization.
