In recent years, science has achieved critical breakthroughs, and nowadays many couples experience the birth of one or more children through assisted reproduction. Evidently, the high pregnancy rates following IVF result from the production and utilisation of ample, good quality eggs and subsequent embryos, and mainly, through the selection process of the most competent embryos based on morphological criteria, morphokinetic data (through Time lapse imaging-EMBRYOSCOPE analysis) and genetic diagnosis (Pre-implantation Genetic Diagnosis/ PGS)
The whole IVF process has been simplified over the last years minimizing the time required to reach the transfer of the embryos back in the uterus. The basic steps of IVF are the following:
The phase of ovarian stimulation begins usually on the first day of the period and lasts for approximately 12 days. Following egg collection and fertilization the developing embryos can be transferred back in the uterus either on the 3rd day of development (at the 6-8 cells stage) or on the 5th day of development (at the blastocyst stage).
