Cryopreservation is the freezing and storage of eggs, sperm, and/or embryos for future use. This allows individuals to preserve their fertility in order to achieve a future pregnancy. It is frequently used in conjunction with fertility treatments such as in vitro fertilization (IVF).

Cryopreservation enables individuals to freeze and store their eggs, sperm, and/or embryos, effectively stopping their biological clock. This is ideal for people who are not ready for parenthood, are transitioning to male, or have been diagnosed with cancer and want to keep their pregnancy options available in the future. Cryopreservation protects and preserves eggs, sperm, and/or embryos for as long as necessary.
Cryopreservation is a relatively safe, advanced procedure that frequently results in a successful future pregnancy. Cryopreservation is the process of preserving fertility by freezing eggs, sperm, and/or embryos at subzero temperatures for later use. The biological age of the eggs, sperm, and/or embryos remains the same after they are frozen and stored.
Egg Cryopreservation – Also known as oocyte preservation or egg freezing, is the process of harvesting, freezing, and storing eggs for future use. Hormones are prescribed to patients to stimulate the ovaries, causing multiple follicles to grow. Eggs that are ready to be fertilized will be retrieved, frozen, and stored.
Embryo Cryopreservation – Embryo cryopreservation freezes a fertilized egg through the process of in vitro fertilization (IVF). During IVF, patients are given hormones to stimulate their ovaries to produce a large number of eggs. Once the eggs have developed, they are gently removed and fertilized with sperm, resulting in the formation of an embryo. The embryo is then frozen and stored for future use.
Sperm Cryopreservation – Men and adolescent boys who have reached puberty can freeze sperm prior to medical treatments, certain types of surgery, chemotherapy/radiation therapy, or other conditions that can harm sperm. Under optimal conditions, healthy sperm can be frozen, thawed, and utilized at a later time.
Ovarian Cryopreservation – Ovarian tissue cryopreservation involves removing the egg-producing portion of the ovary (the ovarian cortex) prior to a patient’s medical treatment, such as cancer surgery, chemotherapy/radiation, or gender affirmation surgery. The tissue is frozen and stored, then transplanted in the future to make pregnancy possible.
Individuals considering cryopreservation should consult with their primary care provider, gynecologist, or fertility specialist for an evaluation and counselling on the risks, benefits, and options best suited to their needs.
There are multiple factors to consider with cryopreservation. A person’s fertility is influenced by a variety of factors, from lifestyle and nutrition to genetics and hormones. Cryopreservation can help individuals or couples get pregnant later in life if they are facing current obstacles such as, but not limited to:
Following an initial consultation with the preferred physician, gynecologist, or fertility specialist, appropriate pre-treatment tests will determine the best way to proceed. Depending on the individual’s goals, IVF cycles may be required prior to the retrieval and storage of the eggs, sperm, and/or embryos. Patients are frequently able to return home the same day as the procedure, with only minor pain and discomfort. It is critical to follow the instructions given by your preferred healthcare provider.
The cost of cryopreservation varies depending on factors such as geographic location, the physician’s clinical experience/technique, the length of time in storage, and additional medical factors such as tests, medications, and IVF cycles (if applicable). In Canada, the cost of cryopreservation alone ranges from $10,000 to $14,000.
The risks of cryopreservation are minimal, but as with any medical procedure, there are risks and complications including, but not limited to:
