Egg freezing has become a useful means for women who want to preserve fertility, but timing plays a critical role. Biologically, the best age for fertility is 23 to 29 years; it is when anti-mullerian hormone (AMH) and ovarian reserve are at their peak. The majority of women in their 20s, however, are focused on building their careers or are not emotionally prepared yet to have a family.

Dr Kaberi Banerjee, Infertility & IVF Expert, Founder & Medical Director, Advance Fertility & Gynecology Centre shares all you need to know:

Although egg freezing in the 20s is most likely to recover healthy eggs,this process is usually used by women with certain medical conditions, such as cancer or who have a strong family history of premature menopause, or even by those who want to delay their pregnancy and want to conceive later on. Freezing eggs early can allow women to pursue personal ambitions with the assurance that they have saved their fertility. However, it is an expensive and time-consuming procedure that requires long-term storage of the eggs.

In the early to mid-30s, egg freezing becomes more common. At this stage, women are more likely to have a clearer idea of their reproductive intentions. Egg quality does begin to deteriorate after 35, but success rates are still good until the late 30s. A meta-analysis confirmed that women who preserve eggs at or before the age of 35 years had a live birth rate of 52%, whereas it was only 19% above 40 years. To achieve a 70% live birth chance, the women will have to preserve more eggs with increasing age—around 14 at 30–34 years, 15 at 35–37 years, and 26 at above 38 years.

The ideal time for freezing eggs varies depending on individual purpose, health, and timing. Physicians advise acting at once for those with established risks, but for others, careful planning during their early 30s will provide the most favorable combination of medical success and personal preparedness.
