The ICSI procedure is used in cases where the patient suffers from: low sperm motility, abnormal amounts of sperm, or the presence of antispermal antibodies. The ICSI procedure is done under an electron microscope. Special glass micromanipulation devices are used on the ovum and sperm (microinjectors and micropipettes). An embryologist selects the fastest and most average built sperm, immobilizes it, and draws it into the microinjector. Afterwards, the sperm is transported with the help of a micropipette and pierces the cytoplasma of the egg with the microinjector (injecting the sperm into the egg).
For residents of Saint Petersburg the IVF and ICSI procedures are practically the same thing. Children born from ICSI and in-vitro fertilization turn out the same as naturally born children.
How It Works:
- At the beginning the eggs (ova) are prepared. Only the best eggs are selected and cultivated until they reach maturity.
- The sperm is prepared. The sperm’s quality is improved with the goal of selecting the most vital specimen for the procedure.
- The ICSI procedure itself is performed by an embryologist, who injects the sperm with the help of a special micropipette into the cytoplasm of the egg.
- Embryo cultivation takes place. The fertilized eggs develop in a special laboratory environment for a period of 2-5 days.
- The embryos are then transported into the uterine cavity using the IVF method.
- 90-95% of embryos successfully develop after fertilization.
- Only 1 sperm is needed for the ICSI procedure to be successful.
When Is In-Vitro Fertilization (IVF) + ICSI Recommended?
- In difficult cases of male infertility (autoimmune infertility, sperm pathology).
- The complete absence of sperm in the semen (in order to make sperm the TESA/PESA procedure may have to take place).
- Failed fertilization in previous IVF procedures.
- Low egg (ova) count.
- Unexplained infertility.
