Intracytoplasmic sperm injection of eggs is the most frequently used technique of egg fertilization. On average, 8-9 out of 10 eggs will fertilize when using this method. During the procedure a single sperm is selected and injected directly into an egg using a microneedle.
This method is especially indicated when the values of sperm parametres are low or in case of previous fertilization failure where ICSI was not applied. Nowadays, this technique is used in more than 90% of couples, even in case of regular sperm parametres, as it minimizes the risk of cycle interruption due to fertilization failure when using conventional IVF.
In cases where we want to test the natural fertilizing capacity of spermatozoa , ICSI technique can be applied to a certain part of eggs to ensure higher chances of successful fertilization , and the second part of eggs combined with sperm in conventional IVF.
Until now, no study has proven any difference between children born after ICSI and children born after spontaneous fertilization.
