When considering fertility preservation, both egg and embryo freezing offer unique benefits and challenges.
Freezing eggs provides reproductive autonomy, allowing individuals to fertilize them with sperm at a later date when they are ready to build a family. This approach is often less expensive, especially for those paying out of pocket, as it involves fewer laboratory procedures compared to embryo freezing. However, the main drawback of egg freezing is the uncertainty surrounding their future potential. Egg quality is primarily determined by the individual's age at the time of freezing, but even with good-quality eggs, not all will survive the freezing, thawing, and fertilization processes.

Embryo freezing, on the other hand, offers greater predictability since fertilization is completed prior to freezing. Embryos that are tested and found to be chromosomally normal have a 60–70% chance of resulting in a live birth once transferred. However, this approach requires a sperm source, whether from a partner or a donor, which may not align with everyone’s current circumstances. Using a partner’s sperm introduces legal complexities, as both parties retain rights to the embryos, potentially complicating future use if the relationship ends. Alternatively, embryos created with donor sperm give the individual full control but might pose challenges if a future partner prefers not to use donor-conceived embryos.
For individuals under 38, egg freezing may be sufficient, as the eggs tend to be better quality and have more predictable outcomes.
For those 38 or older, embryo freezing is often recommended due to the reduced reliability of eggs at that age. Some individuals, if resources allow, choose to freeze both eggs and embryos to maximize future options. Ultimately, the best choice depends on factors such as age, relationship status, financial situation, and long-term reproductive goals. Consulting a fertility specialist can help tailor the decision to your unique circumstances and provide guidance through this complex but empowering process.
