ICSI (intracytoplasmic sperm injection)
ICSI is one of the methods of egg fertilization. The sperm is injected directly in the center of the egg in this micromanipulation technique. The advantage of this method is that it only requires one sperm for one egg. The success rate of fertilization with ICSI is around 90%.
ICSI is used in the following cases:
- low sperm count
- disorders of sperm motility
- when few eggs were collected in OPU
