How to Improve Egg Quality Before Surrogacy in Mexico

As more families begin planning for the future, surrogacy in Mexico has become an important option for achieving parenthood. During consultations, many intended parents focus on the surrogacy process and success rates but often overlook an even more fundamental factor—egg quality. In reality, whether or not you choose surrogacy, an embryo's developmental potential depends first and foremost on the quality of the egg and sperm.

Why Is Egg Quality So Important?

Egg quality affects not only whether fertilization occurs successfully, but also embryo development, implantation, and pregnancy outcomes.

High-quality eggs are more likely to produce embryos with strong developmental potential. When egg quality declines, even successful fertilization may result in embryo arrest, chromosomal abnormalities, or repeated implantation failure.

How Is Egg Quality Evaluated?

At present, there is no single test that can directly determine whether an egg is "good" or "bad." Instead, physicians perform a comprehensive assessment based on multiple indicators.

These include a woman's age, anti-Müllerian hormone (AMH) level, antral follicle count (AFC), hormone profile, and reproductive history.

Age remains the most significant factor affecting egg quality. As women get older, both egg quantity and quality gradually decline, while the risk of chromosomal abnormalities increases. After age 35, the likelihood of producing high-quality embryos generally decreases, which is why fertility specialists often recommend an early fertility evaluation for those planning a family.

Which Lifestyle Factors Affect Egg Quality?

Although age cannot be changed, many lifestyle habits can influence ovarian function and the environment in which eggs develop.

Chronic sleep deprivation, smoking, excessive alcohol consumption, prolonged stress, obesity, and extreme dieting may all disrupt hormonal balance and follicle development.

On the other hand, maintaining regular sleep habits, eating a balanced diet, exercising appropriately, and keeping a healthy body weight help create a more stable environment for follicle development. Individuals with thyroid disorders, insulin resistance, or other endocrine conditions are also encouraged to receive appropriate medical management.

How Can Assisted Reproductive Technology Improve Success Rates?

Modern assisted reproductive technology not only uses individualized ovarian stimulation protocols to obtain more mature eggs, but also combines advanced laboratory techniques to improve overall treatment outcomes.

After fertilization, embryos are typically cultured to the blastocyst stage before undergoing IVF-PGT. Through preimplantation genetic testing, embryos with stronger developmental potential can be selected, improving overall pregnancy success rates while reducing the risk of miscarriage caused by chromosomal abnormalities. This has become one of the major advantages of modern assisted reproduction.
