How to Cope With Anxiety Over Low Egg Retrieval? A Key Step in Mexico Surrogacy

Before deciding to welcome a child through surrogacy in Mexico, many families first go through an anxious stage: seeing others retrieve a dozen or even twenty eggs in one cycle, while their own retrieval yields only a few, naturally raises questions—is something wrong with their physical condition? Did something go wrong with the ovarian stimulation plan? Will having fewer eggs affect their chances of having a child?

In fact, the number of eggs retrieved alone cannot directly determine the outcome of a cycle. For families planning to have a child through surrogacy in Mexico, it is more important to consider the entire pathway, from ovarian reserve and the number of mature eggs to fertilization, embryo culture, and subsequent embryo selection.

Why Do Egg Retrieval Numbers Vary So Much Between People?

The number of eggs retrieved is primarily related to ovarian reserve. The number of follicles varies from woman to woman, and factors such as age, ovarian function, and previous reproductive history can all affect the number of follicles that can be recruited and developed during a cycle.

Age is also an important factor. As age increases, ovarian reserve may gradually decline, making a reduction in the number of recruited follicles more common. Therefore, even when two people use similar ovarian stimulation medications, the final number of eggs retrieved can be completely different.

In addition, the ovarian stimulation protocol, baseline hormone levels, antral follicle count, and the ovaries' response to medication can all affect the final egg retrieval outcome. Someone retrieving 15 eggs in one cycle does not mean that retrieving 8 eggs is a “failure.” Likewise, retrieving a large number of eggs does not necessarily mean that more transferable embryos will ultimately be obtained.

What Really Matters Is the Number of Mature Eggs

Not all eggs retrieved are necessarily mature. Only eggs that have reached the appropriate stage of maturity have a greater opportunity to proceed to subsequent fertilization.

Therefore, when evaluating an egg retrieval outcome, it is important to look beyond the total number of eggs retrieved and also consider the number of mature eggs, fertilization results, and subsequent embryo development.

Assisted reproduction is a gradual selection process. Eggs need to mature and be fertilized, and fertilized eggs must continue dividing and developing to the blastocyst stage. Not every egg will progress through every stage to the end.

Why Is “Low Egg Count” More Concerning When Preparing for Pregnancy at an Advanced Age?

When some families begin preparing for surrogacy, the female partner may no longer be at an age associated with relatively higher fertility. As age increases, ovarian reserve and egg quality change. Therefore, a lower number of retrieved eggs may occur, while greater attention also needs to be paid to subsequent embryo development. After embryos develop to the blastocyst stage, IVF-PGT can be used for genetic testing to further understand their chromosomal status and provide more information for subsequent embryo selection.
