ICSI in Spain

How is ICSI carried out?
The woman first takes fertility drugs to stimulate the ovaries for fertilization while the man produces a sample of sperm. If he has no sperm in his semen, doctors extract it under anesthesia using a needle. The doctor removes the woman’s eggs with a needle and a single sperm is injected into an individual egg. The fertilized eggs become embryos and are transplanted into the uterus. Any remaining embryos may be frozen for possible use in the future.

How often is ICSI used?
