If you decide to proceed with ICSI, we will make every effort to inject as many eggs as possible. It is important for you to understand that only eggs that are mature can be injected with sperm. Our PICSI treatment centre in noida can easily tell if an egg is mature or immature. Although the immature eggs are incubated with sperm, the likelihood of fertilization is very low. On average, we are able to inject 75 percent to 80 percent of the eggs that are recovered.
