Embryo Freezing - Dr. Senai Aksoy

Embryo Freezing

After transfer there are usually excess embryos that can be frozen for later use. Only embryos that are of good quality are suitable for freezing. In Turkey, according to regulations embryos can be stored for 5 years. Embryo freezing does not harm the embryo. We currently prefer vitrification over slow freezing as the former is associated with higher survival rates after thawing higher pregnancy rates after transfer.

There are over 700,000 babies worldwide that were born after the transfer of frozen-thawed embryos.

We have a very successful embryo-freezing program. Our pregnancy rates for frozen-thawed embryo transfers are approximately equal to fresh transfers.

A couple can elect to have their frozen embryos replaced after an unsuccessful attempt or after delivering a baby. Preparation for frozen embryo transfer is a relatively simple procedure that entails stimulation of the inner lining of the uterus with orally used medications.
