Embryo freezing, also known as embryo cryopreservation, is a process in which embryos created through IVF are preserved for future use. At Almond Blossoms, embryos are frozen only once they reach the blastocyst stage on Day 5 or 6, as research shows this stage offers the highest implantation and live birth rates. We use vitrification — an ultra-rapid freezing technique that prevents ice crystal formation — achieving survival rates of over 95% compared to older slow-freezing methods. Embryo freezing can be beneficial for patients delaying embryo transfer for medical or personal reasons, those undergoing Preimplantation Genetic Testing (PGT), cancer patients preserving fertility before treatment, and couples wishing to store surplus embryos for later use.
Vitrification rapidly cools the embryo to a glass-like state within milliseconds, avoiding damage from ice crystals. This method has become the gold standard recommended by both ESHRE and ASRM, delivering consistently high thaw survival rates and excellent outcomes for blastocyst-stage embryos. Blastocysts are more resilient to freezing and thawing, and minor cell loss rarely affects their ability to result in a healthy pregnancy. Evidence also shows no increased risk of congenital anomalies in babies born from frozen embryos. By focusing exclusively on blastocyst freezing, Almond Blossoms maximises embryo viability, safety, and overall success rates.
In the UAE, embryos are stored in liquid nitrogen at −196°C for an initial period of five years, with mandatory annual renewals and the option to extend for an additional five years. When you are ready, embryos can be thawed and transferred during either a natural or medicated frozen embryo transfer (FET) cycle. Success depends on factors such as the woman’s age at the time of egg collection, embryo quality, and uterine receptivity at transfer. Embryo freezing offers couples flexibility in family planning, allowing treatment to be timed for optimal health, readiness, and life circumstances.
