OUR TECHNOLOGIESState-of-the-art technology

State-of-the-art technology

We use the latest, ultrafine needle to puncture the egg for fertilisation in order to spare the ovaries thus reducing the potential risk of postoperative complications. We are constantly striving to increase the quality of treatment.

More about our technologies

The popularity of ICSI continues to grow

90% of couples at the clinic would like to use this method, even if the man has normal semen analysis results. Using ICSI, we are able to minimise interruption of the cycle because eggs are not fertilised using the “classic or conventional IVF” method, where the egg is fertilised with sperm in a culture dish spontaneously.

The ICSI method

Experience with the ICSI method

ICSI is a long-proven method that was first used by doctors at the Brussels University Hospital in 1991. The first woman in the Czech Republic became pregnant thanks to IVF/ICSI in 1995. Today, this method is widely used throughout the world, as evidenced by ESHRE (European Society of Human Reproduction and Embryology) registers, which monitor the use of individual techniques in European countries.

So far, no studies have shown any difference in the psychomotor development of children born after ICSI and children born from spontaneous conception. Based on current knowledge, it can also be said that the fertilisation of eggs using ICSI does not increase the risk of delivering a foetus with a congenital defect compared to pregnancies following spontaneous fertilisation.
