Embryo freezing is a process that preserves fertilized embryos from an IVF cycle for future use. At CARS in Toronto, embryos are frozen using a rapid freezing technique called vitrification, which prevents ice crystal formation and protects embryo quality. When you’re ready to conceive, the embryos are thawed and transferred, offering excellent success rates for future pregnancies.

Embryo freezing is ideal for couples planning delayed parenthood, same-sex partners using donor eggs or sperm, and patients undergoing fertility treatment after cancer. It’s also a great option for individuals who want flexibility in their fertility journey while preserving high-quality embryos for future IVF transfers.

Embryos can be safely stored for many years without losing quality, thanks to advanced cryopreservation technology. At CARS, our accredited facility in Toronto maintains secure, temperature-monitored storage tanks to ensure the long-term safety and viability of your embryos until you’re ready to use them.

The cost of embryo freezing is generally lower than undergoing repeated IVF cycles, as it allows you to use previously fertilized embryos for future attempts. At CARS, we provide transparent fertility treatment cost information and flexible storage plans. Embryo freezing offers both financial and emotional peace of mind, helping you plan your family on your timeline.
