Frozen Eggs and Embryos

Since 1988, our Toronto Reproductive Center has been assisting single men, single women, and couples in preserving their fertility for future use by freezing sperm, eggs, and embryos for over 30 years.

The number and quality of eggs in women decrease with age. Typically, ovarian function in women begins to decline around the age of 33, and by the age of 40, the quality of eggs in most women significantly diminishes. The Reproductive Center's Frozen Egg Project is an essential option for women looking to preserve their fertility and secure it for the future.

The collected sperm, eggs, or embryos are preserved in ultra-low-temperature liquid nitrogen tanks, ensuring that the best biological samples at the time of collection are stored for future use. Currently, these samples can be stored for up to 30 years.

Additionally, individuals facing serious medical conditions such as cancer have the opportunity to preserve their eggs or sperm before undergoing chemotherapy or radiotherapy. This is because radiotherapy, chemotherapy, and some medical procedures may harm the ovaries or reduce a patient's reproductive capability.

How to Freeze Eggs?

Freezing eggs involves a 10 to 12-day ovulation-promoting cycle, which stimulates the maturation of more small follicles in the ovary. During this period, doctors will closely monitor follicle growth using blood tests and ultrasound scans. The egg extraction process is typically painless and takes about 10-15 minutes.

Once the eggs are frozen, you can choose to thaw them when you're ready. They can then be fertilized with sperm from a male partner or a sperm donor to create embryos, which can subsequently be implanted in the uterus for pregnancy.

At our reproductive center cooperative clinic, we have a team of experienced clinical reproductive experts and skilled medical professionals. We're here to provide you with a detailed explanation of the egg/sperm/embryo freezing process to ensure the healthy birth of your future child.
