Female reproductive ability has a specific duration. Age is an important factor that drastically affects fertility and with age progression, the chance of pregnancy decreases.
This decline translates into a decrease in the quantity and quality of eggs that begins strongly after 35 years, accelerates after 37, and fertility sharply declines after the age of 40.
The benefit of this method is that the eggs keep their quality unchanged, regardless of the time they remain frozen. During thawing, the eggs have the same dynamic and prospects of pregnancy as they had when they were frozen.
Because the egg quality is better at younger age, it is recommended to freeze the eggs as early as possible. Ideal age is between 30 and 35 years.
Today, compared to earlier decades, women start a family at an older age for personal, social, financial, or other reasons. To prolong their fertility, they need to “freeze” their biological clock. Egg freezing is the only realistic way to maintain and prolong female fertility.
It is practiced in many countries and some consider it to be a method of preventive medicine against declining fertility with age.
For freezing an IVF treatment is followed until the stage of egg collection. This is followed by freezing and storage of the eggs. When a woman decides to have children and cannot conceive naturally, she will have IVF with the frozen eggs.
Candidates for the method are women who:
- Plan to have children at an older age
- Have a low value of the hormone AMH (antimullerian hormone) and a small number of antral follicles, which translates into a low ovarian reserve
- Have a history of premature menopause in the family
- Have a history of ovarian surgery due to cysts
