In Vitro Fertilisation
IVF comprises a fertilisation technique outside of the body. By means of extra-corporeal insemination techniques these patients are treated, where neither natural induced pregnancy nor insemination yielded a pregnancy. This may have causes in malfunctioning tubes or because of tubes that were extracted surgically. Typical causes may be inflammation, adhesions, endometriosis, tubal pregnancies or other abdominal operations.
For this treatment the ovaries will be stimulated hormonally, and then eggs will be extracted through ultra sound supported follicleaspiration. These eggs will then be inseminated outside the body with the partners semen, that has been processed for fertilisation. In principle the insemination of the egg is the same as under a natural fertilisation, only with the difference that is takes place outside the body. The fertilised eggs, now called embryos, will be transferred into the uterus either in a 6-8 cell state or after 5 - 6 days as blastocysts. If the fertilised eggs development is satisfactory, we prefer the blastocyst transfer, since this yield a pregnancy rate of more than 45%.
