IVI is one of the European centres with the best pregnancy rates: 9 out of 10 couples that consult IVI due to problems with infertility and who put their trust in us achieve their goal.

The effectiveness of assisted reproduction treatments varies depending on the technique chosen and the reproductive prognosis of the patients. At IVI assisted reproduction clinics, techniques such as egg donation, give an accumulated pregnancy rate of close to 97% over three attempts.
