Embryo cryopreservation (freezing)

If during IVF procedure more embryos were obtained than are coing to be transferred into the uterus, these embryos, if of good quolity, can be frozen. These frozen embryos are the property of the couple alone and can be used for the next attempt or a next pregnancy. The benefit of cryopreservation is that a woman has an additional chance to conceive without stimulation procedure and follicular puncture. She only needs to prepare for the embryo transfer with tablets. This process starts in the first 3 days of menstruation, lasts for two weeks and requires 1-2 US examinations.

Cryopreservation is a biological "support" for the couple since it is not always clear whether the next possible stimulation and fertilization attempt will be successful. Embryo cryopreservation increases the couple's chances to conceive. Embryo cryopreservation is fairly economical since preservation, unfreezing and embryo transfer costs are much lower compared to the cost of a new IVF attempt.

The cryopreservation is a reliable and trusted approach. It has no negative impact on the fetus and pregnancy. Some embryos, however, can be lost during freezing - thawing processes since not all embryos survive them. The issue of freezing of the excess embryos is usually discussed with the doctor before IVF treatment starts.

Embryo cryopreservation makes the treatment milder and more economical.
