What is ICSI?
Intracytoplasmic sperm injection (ICSI) is a very sophisticated micromanipulation technique consisting in the introduction of a sperm into an egg using a very fine needle.
When is this technique used?
ICSI is used when the patient has very few sperm, since only one sperm is needed for each egg. It is also used in couples who have had a failure of fertilization after an IVF treatment, in patients who require the use of epididymal or testicular sperm, and in couples to whom a preimplantation genetic diagnosis is going to be performed.
This technique constitutes a spectacular advance to solve fertility problems due to male factor, since a single spermatozoa can be successfully used from poor quality semen samples, even from the epididymis and testis.
Currently this technique is most often used to fertilize the majority of the eggs in our center, because we can obtain more fertilized eggs in order to select the best embryos for transfer. Our professionals in charge of this technique have microinjected the biggest amount of eggs in the country.
What steps do you follow?
The whole process before and after ICSI is the same as for in vitro fertilization, the only difference is that the eggs must be washed to remove the surrounding granulose cells in order to facilitate the microinjection process.
• Thanks to ICSI you can get pregnant even though your couple has previously had a vasectomy, since through a testicular biopsy we can obtain sperm to microinject.
• In order to perform this technique the signing of an informed consent by the two members of the couple is required, as well as a negative infectious serology, to ensure the good health of your child.
• You can get pregnant even though your couple has no sperm in the ejaculate (Azoospermia). By performing a testicular biopsy, testicular sperm can be obtained, and with ICSI the eggs produced by the patients are inseminated.
• Assisted reproduction treatments are not unnatural treatments. The nature or course of pregnancy is not altered. All we do is restore fertility, facilitating the meeting between the egg and sperm in order to form an embryo with the same characteristics as if it has been formed in the uterus.
• Assisted reproduction treatments have minimized the side effects. These treatments do not alter the reproductive tract or the rest of the body.
