Intracitoplasmic sperm injection (ICSI) is a method that significantly increases the chances of pregnancy. It is the process of injecting sperm into an egg.
What is ICSI?
In order to have a natural pregnancy, the secreted ejaculate (sperm) travels through the vagina, uterus and fallopian tubes, and reaches a mature, newly ovulated egg. Between 300 and 500 million sperm are ejaculated in one ejaculate, while only a few tens of thousands reach the ovum, and only one sperm can fertilize the ovum - the one that penetrates it first. It is this fusion of sperm and egg that we call fertilization.
Intracytoplasmic sperm injection (ICSI) is a method by which sperm are injected directly into a mature, ovum cell to fertilize. This technique is used in couples in whom the previously described sperm pathway is disabled, for various reasons.
Who is it recommended for?
ICSI as the most advanced technique of medically assisted fertilization is recommended to:
- Men with reduced sperm count; poor mobility and poor morphology,
- Couples in whom classical IVF treatment did not succeed or fertilization did not occur,
- Men who have had a vasectomy,
- Couples who are recommended for PGT.
- In infertility resulting from immune factors,
- Men who have retrograde ejaculation;
- In men who have had TESA / Micro-Tesa
The ICSI technique allows the embryologist to directly select the sperm that are of the highest quality and have the best morphological characteristics, and connect them to the egg. This increases the chance of pregnancy more than any other medically assisted fertilization technique.
The ICSI procedure requires a highly educated embryologist, as well as state-of-the-art equipment. A previously processed sperm sample, from which the highest quality and morphologically correct sperm are extracted, is connected to a mature egg cell, through a microscope and micromanipulators.
The procedure is repeated as many times as we have mature eggs and sperm, all with the aim of obtaining a larger number of quality embryos.
