Why preserve fertility?

For women, fertility decreases gradually over time and from the age of 35, it begins to drop more rapidly. As the number of eggs available, known as the ovarian reserve, decreases, the eggs also begin to lower in quality. This makes it more difficult for women to conceive naturally as they get older. This is a normal biological process, which cannot be altered.

However, the reality is that today more and more women are choosing to have children later in life. This may be due to personal, social or career circumstances. As a result, many women now preserve their fertility by freezing eggs at a younger age, allowing them to be used in the future.

Through the freezing method known as vitrification, the eggs retain their quality at the time of preservation. This means if you decide you want to have a baby later in life, you can use these eggs and have the same chances of getting pregnant as you would have had at the time of preservation.

Preservation of Fertility

When is it recommended?

Women who might not be ready for a family right now, but wish to have the option of having children later in life. The best time to preserve fertility is before the age of 35. Beyond the age of 35, it is still possible to freeze eggs however the eggs will likely be lower in quality and quantity, and might not provide optimal chances of a pregnancy if used in a fertility treatment.

Success Rates

Thanks to the freezing technique known as vitrification, we are able to maintain the quality of the eggs until the day they are thawed, with very high survival rates. This rate is currently over 95% for eggs collected from women under the age 35, which is much higher than that of traditional freezing methods. They can also be kept frozen for longer periods, with no time limitation.

When used in assisted reproductive treatment, previously vitrified eggs do not negatively affect the chances of the success in any way, as the oocytes maintain the same quality at the time they were preserved. In addition, the IVF success rates achieved with eggs that have been previously frozen and thawed are equal to those achieved with fresh eggs.
