At Raffles Fertility Centre, our protocol involves freezing exclusively mature eggs, as these are the ones capable of resulting in a pregnancy. The quantity of eggs recommended for freezing is contingent on both the individual's age and the outcomes of their ovarian reserve tests. For women aged 35 or under with strong ovarian function, we generally suggest freezing between 10 to 15 mature eggs. Conversely, for women over 35 or those with reduced ovarian function regardless of age, we recommend consulting your doctor to determine the ideal number of attempts. This approach allows for multiple opportunities to conceive in the event that a cycle is not successful.
