What does success in an IVF treatment mean?

Getting pregnant fast and giving birth to a healthy singleton baby. As a matter of fact, we can indeed offer you absolutely leading pregnancy rates (click on image to view additional information):



In 2019, our team was rewarded with 47% pregnancies in fresh, and 53% in thawing cycles. With pre­implantation testing (see thawed euploid blastocysts in the table) we could even observe 66% pregnancies despite a high average female age of 38.5 years. The average number of transferred embryos dropped from 1.8 (2015) to 1.1 (2019) while maintaining success rate - a very welcome consequence of the new Swiss Reproductive Medicine Act!


Such figures can only be attained thanks to impeccable teamwork of doctor, biologists, nurses and assistants, putting an emphasis on details like comprehensible instruction in self-injections, and relaxed setting during embryo transfer.


However, a clinical pregnancy with gestational sac on ultrasound is just the beginning. 18% to 25% of those pregnancies will unfortunately end als early miscarriages or, rarely, ectopic pregnancies; the rate of early miscarriage rises exponentially with the age of the woman. Once you have reached 12 weeks, you can breathe deeply and break the news, because 98% of those babies will be born (live birth), and 96% to 97% will be healthy.

Our practice strives hard to optimise success rates even further, but without jeopardising the quality of your treatment:

  • In women younger than 38, as well as after preimplantation testing, only a single blastocyst of optimal quality should be transferred in order to reduce risky twin pregnancies. This is termed elective single embryo transfer (eSET).
  • Splitting treatment in stimulation, freezing and transferring the embryo four weeks later (so-called freeze-all strategy) is increasing world-wide. We continue to have excellent pregnancy rates in fresh cycles, but the list of situations when freeze-all is recommended is getting ever longer. Special emphasis is hereby put on measuring progesterone in blood.


Having the privilege to deliver many babies, both after natural conception and after fertility treatments, obstetrics is my ideal compensation to reproductive medicine, and gives me constant reassurance that IVF produces many healthy babies that are born into happy families.
