ICSI involves the use of a holding pipet to keep the egg in place and in injection pipet to inject the sperm inside the egg. Pinching by the holding pipet and the zigzag movement of the injection pipet can be very stressful to the egg so we developed an ICSI technique that avoids these stressors.
Less stress = higher fertilization rate and higher embryo quality. The national average ICSI fertilization rate is around 60%, ours is greater than 80%.
