More and more people are incorporating the timing of childbearing into their long-term life plans. Factors such as work schedules, marriage and childbearing timelines, and personal life arrangements can make “I don’t plan to have children now” and “I don’t want children in the future” two completely different things. As fertility preservation becomes increasingly familiar to more people, egg freezing in the U.S. has also continued to grow. According to the latest preliminary national data released by SART for 2024, a total of 39,133 non-donor egg freezing cycles were initiated, with 18,750 cycles involving women under 35, making this the largest age group. This figure also shows that egg freezing has become an option for many women who want to plan their future fertility in advance.

What Exactly Does Egg Freezing Preserve?

Egg freezing does not determine the outcome of future fertility in advance. Instead, it preserves mature eggs. After ovarian stimulation and egg retrieval, doctors assess the maturity of the eggs and then preserve them using freezing technology. When they are needed in the future, the eggs still need to go through thawing, fertilization, and embryo culture.

According to SART data from 2024, there are clear differences in the number of eggs retrieved at each retrieval according to age. Women under 35 had an average of 18.8 eggs retrieved per cycle and an average of 14.5 eggs frozen; women aged 35 to 37 had 15.1 eggs retrieved and 11.6 eggs frozen, respectively; while women aged 38 to 40 had 12.3 eggs retrieved and 9.4 eggs frozen. Overall, the average number of eggs retrieved and frozen tends to decrease with increasing age.

Why Consider Embryos After Egg Freezing?

Frozen eggs need to be thawed in the future and then combined with sperm to form embryos, followed by further embryo culture. Not every frozen egg can be successfully fertilized after thawing, and not every fertilized egg can continue developing into a blastocyst. Therefore, there are still multiple stages between egg freezing and obtaining embryos suitable for transfer.

If IVF-PGT is planned later, once embryos have developed to the appropriate stage for testing, relevant testing can provide information about chromosomes and relevant genetic characteristics, offering additional reference for subsequent embryo selection. For families planning to complete pregnancy through Mexico surrogacy, understanding this entire pathway in advance is more important than simply focusing on how many eggs have been frozen.

How Should Mexico Surrogacy and Egg Freezing Be Connected?

Surrogacy addresses who carries the pregnancy, while egg freezing addresses when eggs are preserved. They are different stages of the fertility planning process.

If it has already been determined that pregnancy may be completed through Mexico surrogacy in the future, it is possible to organize plans for eggs, sperm, embryos, and subsequent pregnancy arrangements earlier. For families who hope to use their own eggs, preserving eggs in advance can complete an important part of the fertility plan ahead of time. When it is actually time to create embryos, the eggs can then be thawed and proceed through fertilization, embryo culture, IVF-PGT, and other steps based on the circumstances at that time.
