Yes. Generally, we advise women to consider freezing their eggs within the age range of 30 to 38, with the optimal window falling between 32 and 35. Freezing eggs at a younger age often yields more favorable outcomes. If you were to freeze eggs at 30 and later utilize them at 40, your chances of success and the likelihood of miscarriage would be comparable to those of a 30-year-old. Essentially, you're securing your success rates based on the age at which the eggs were frozen. An advantage of this approach is that while our ovaries age over time, the uterus typically remains healthy until around age 50. Assuming you're in good health, there's usually no cause for concern if you choose to use your frozen eggs in your 40s.
