Quite often, during in vitro fertilization programs embryos can be stored using cryopreservation technology. In addition, the ultra-fast freezing — vitrification — extend the life of the embryo, so in the future — their use in treatment of infertility. Sperm cells can also be frozen using this method. They remain intact for years! This method avoids the formation of ice crystals that can damage the cells during thawing. It is very important that after vitrification about 98% of the embryos thaw successfully. Our embryology laboratory has equipment of the highest standards. That’s how we are fighting for every new life!
Embryos can be frozen at any stage of development. But the best results (for a successful pregnancy) occur when the embryos are frozen on 5-6th day, ie at the blastocyst stage. Each embryo is a separate numbered cryotope. 1 to 2 embryos at the request of patients can be transferred into the uterus. Cryopreserved embryos are stored in our Cryobank under the watchful supervision of experts.
When using the method of cryopreservation a woman gets an extra chance of embryo transfer without re-stimulation and follicle puncture.
Freezing oocytes can be tricky. Female cells are very sensitive to the process of freezing, so our specialists perform the procedure of cryopreservation of oocytes very carfully. But sperm can be frozen very easily! Often couple resort to freezing spermatozoa when a man cannot attend the clinic on the same day as his partner.
The cryoprogram has a significantly higher clinical pregnancy rate compared to programs carried out in open loop.
There is no evidence to show that the cryopreservation has a negative impact on the future health of your baby. Worst case scenario – you may have to endure your child’s love of sledding!
