What Is Embryo Freezing?

Embryo freezing is a process where embryos are preserved at very low temperatures using liquid nitrogen for future use in fertility treatments. This allows couples to plan pregnancy at a later time without affecting fertility outcomes.


Embryo freezing is commonly recommended when women are undergoing treatments like chemotherapy or radiotherapy, or when there are multiple embryos after IVF. Using advanced vitrification techniques, embryos remain viable and safe for future transfer.

How Are Embryos Frozen?

Embryos undergo cryopreservation followed by vitrification, which prevents ice crystal formation and preserves cell integrity. Once frozen, they are stored in liquid nitrogen tanks until needed for embryo transfer.

Embryo freezing provides flexibility in family planning and increases the chances of successful pregnancy by allowing multiple transfer attempts from the same IVF cycle.

Embryo freezing is a procedure where embryos are frozen and stored at very low temperatures, usually with the help of liquid nitrogen, for later use.

Embryos are frozen for various reasons, such as planning pregnancy at a later stage or when ovaries may be damaged due to treatments like chemotherapy or radiation.

Embryos are preserved through cryopreservation and vitrification, which prevents ice crystal formation and ensures embryos remain viable in liquid nitrogen storage.

Embryos can be stored for many years. On average, they are stored for 10 years, but in some cases, they may remain viable for longer.
