Oocytes, sperm and thereafter embryos are placed into special mediums (cultivation solution), which provide suitable conditions for their further development.
Cultivation solutions are every day in exact intervals adjusted so they could provide optimal and as natural conditions as possible.
Embryos are cultivated for 2-6 days and then are transferred into uterine cavity. Supranumeral embryos can be cryopreserved and stored for future use.
It is laboratory technique, which significantly improves results of IVF and ET method.
Using special cultivation solutions, it is possible to prolong the cultivation duration for 5-6 days (blastocyst stage). The advantage of this method is the possibility of selection of the highest quality embryos for transfer which improves the chances of pregnancy. Usage of blastocyst culture is suitable mainly when the count of fertilized ova is sufficient (5 and more). Determining the optimal day for embryo transfer is individual and can change during recurrent IFV cycle.

Our clinic provides its patients with the option to use a modern method of viewing and scoring embryos in the incubation box during the treatment. The box is equipped with micro cameras which are connected to computer and microscope.
The unique PrimoVision device monitors embryo development. Development data are continuously evaluated and the result is being recorded. Embryologists have constant control over the embryo conditions. Analytical program helps embryologists with the selection of most suitable embryos for embryo transfer.
Cameras also allow to provide the treated couple with a recording of embryo development.
Up to certain size, embryo develops under sturdy layer. In order to achieve pregnancy the embryo must leave this layer after the transfer to uterus. This is superior embryological technique, during which is made a hole (by laser) into the sturdy layer through which the embryo leaves this layer. Assisted hatching is recommended for embryos with strong sturdy layer or in the cases of so called implantation failure – embryo failed to implant itself in previous cycles.
Mature embryos are subsequently transferred into the woman’s uterus.
