Embryo freezing in Istanbul: compare private hospitals with a clear summary

Embryo freezing keeps extra embryos from one IVF cycle for a later transfer. Here is the short version, the questions that matter, and how we help you choose between our partner hospitals. The medical details belong on each hospital's page.

Checked against the sources at the end of this page on 2 November 2026.

MedHealthBridge is not a hospital. We are an independent guide. We compare private hospitals in Istanbul and help you choose.

The summary

What it is. Good embryos that are not transferred can be frozen [3]. The usual method is vitrification, a very fast freezing in liquid nitrogen [3] at about −196 °C [7].
Why. Spare embryos after a transfer, a very strong ovarian response (to lower the risk of OHSS), or a transfer timed for a well prepared uterus [1][2][3].
Timeline. Stimulation takes about 10–14 days [1]. Egg collection takes about 20–30 minutes, and the wife goes back to the hotel the same day [2]. Embryos are watched for 2 to 5 days, then frozen [1]. The transfer happens in a later month, and the pregnancy test comes about 10–14 days after it [1][2].
Success. Published information from an Istanbul IVF centre says frozen transfer success may be close to fresh transfer [1]. No one can promise a result [3]. The result depends mainly on the wife's age at egg collection, her health and her response to treatment [1][7].

Who can do it in Turkey

Legally married couples only, with the wife's eggs and the husband's sperm [2][4].
No donor eggs, no donor sperm, no donor embryos, and no surrogacy [2][5].
You need an apostilled marriage certificate with a certified translation [2].

If your plan needs a donor or a surrogate, Turkey is not the place for it. We tell you before you book.

Storage rules

According to Biruni Hospital, five years of storage, which can be extended by another five years, so ten years in total. The extension needs the couple's request and the approval of the competent authorities [2][4][6].
The yearly signed request was annulled by Turkey's Council of State (Danıştay) on 17 April 2025 [6]. Some centres may still ask you to renew consent each year.
Embryos can move to another centre inside Turkey if both of you apply in writing [4].
