What does success in an IVF treatment mean?

The answer seems simple: getting pregnant! As a matter of fact, we can indeed offer you absolutely leading pregnancy rates:



The above original (anonymised) screenshot shows my self-programmed IVF planning tool. In 2015, our team was happy to announce a 51% pregnancy rate with fresh and close to 40% with thawed embryos, despite a high average age of the women exceeding 37 years. Such figures can only be obtained 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 younger women, it can make sense to transfer just one embryo of optimal quality. This is termed elective single embryo transfer (eSET).
  • Sometimes, but certainly not in all treatments, one can wait five days until the embryos have developed into blastocysts. According to new research data from the UK, the longer period outside the mother's womb can have certain disadvantages, except when using low-oxygen culture (what we have been doing since 2013). Blastocyst culture has obviously the significant advantage to transfer (or freeze) only embryos who have already made an important developmental step (from day 3 to day 5).


The baby boy above was conceived naturally, but is so cute that it needs mentioning! 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 even after IVF, many healthy babies are born into happy families.
