IVF is a multiple-step process that consists of ovary stimulation through the use of medication, oocyte retrieval, egg fertilization outside the body (using ICSI if required), embryo transfer into the uterus and finally  vitrification of remaining embryos . This medical process in stages is described in detail in the part procedure and medication.

  2. Embryos

In-vitro fertilization (IVF) is the procedure of fertilization outside the body and subsequent transfer of an embryo into the uterus. Primary indications for IVF are the following: fallopian tubes dysfunction meaning that the egg and sperm cannot meet, decrease in sperm quality, endometriosis or unexplained infertility. The efficiency of IVF treatment depends on multiple factors for example type and a period of infertility. However the most important factor is female age.

We are very happy and proud of our success rates in both IVF and ICSI treatments with own women’s eggs which are high due to individually designed pretreatment and stimulation protocols. Even without PGS, including the patient group of advanced reproductive age and gladly present the results below:

As you already know the success rates of IVF and ICSI with own eggs decline with the age of a woman. This happens due to the egg aging process which starts after 30 and results in chromosome abnormality in more and more eggs, which makes them incapable of creating a healthy ongoing pregnancy and/or a healthy child.
In women:

  • 20-25% eggs are already abnormal in the age of 30
  • 40-45% of eggs are abnormal in the age of 35
  • 70-75% of abnormal eggs in the age of 40
  • almost all eggs are abnormal after the age of 42

Luckily there is a genetic method to help sort out the abnormal eggs and embryos and to create a pregnancy with a healthy child. 

According to our own results, checking your embryos for all the 23 chromosome pairs allows you to increase your chances of becoming pregnant from 20-53% in IVF in different age groups to 60% with just one embryo transferred independent of your age!
