Can Mexico Surrogacy Prevent Chromosomal Abnormalities?

As assisted reproductive technology continues to advance, more families are exploring Mexico surrogacy as a way to welcome a new baby through third-party reproduction. At the same time, one of the most frequently asked questions is: Can surrogacy solve the problem of chromosomal abnormalities in babies?

Surrogacy Does Not Change an Embryo's Chromosomes

Many people mistakenly believe that choosing surrogacy automatically reduces the risk of chromosomal abnormalities.

In reality, a surrogate mother is responsible for carrying the pregnancy and giving birth. She does not change the embryo's genetic information. An embryo's chromosomes come from the egg and sperm. Therefore, if the embryo itself has a chromosomal abnormality, even a healthy surrogate cannot fundamentally change that condition.

For this reason, high-quality embryos remain the foundation of a successful Mexico surrogacy journey.

What Increases the Risk of Chromosomal Abnormalities?

Chromosomal abnormalities can result from multiple factors, with maternal age being one of the most significant.

As women get older—particularly after age 35—the likelihood of chromosomal abnormalities in eggs gradually increases, while the chance of producing chromosomally normal embryos decreases. In addition, inherited genetic factors, sperm quality, and random errors during cell division may also contribute to chromosomal abnormalities.

This is why many families undergo comprehensive genetic risk assessments before beginning assisted reproductive treatment, rather than focusing only on whether pregnancy can be achieved.

How Does IVF-PGT Help Select Embryos?

Today, modern assisted reproductive technology allows fertilized eggs to be cultured to the blastocyst stage before undergoing IVF-PGT.

Embryo genetic testing helps identify embryos with better developmental potential, improving overall pregnancy efficiency while reducing the risk of miscarriage caused by chromosomal abnormalities. For families with advanced maternal age, recurrent pregnancy loss, or those hoping to improve success rates, IVF-PGT has become one of the major advantages of assisted reproduction.

It is important to understand that IVF-PGT does not "treat" chromosomal abnormalities. Instead, it helps identify embryos that meet testing standards among multiple embryos, providing a more scientific basis for embryo selection before transfer. From fertility assessment and individualized ovarian stimulation protocols to blastocyst culture, IVF-PGT, and the subsequent surrogacy process, every step contributes to the final outcome.

Power Fertility Clinic is a fully licensed fertility center in Mexico that operates under U.S. FDA standards and is directly managed by a U.S. reproductive healthcare organization. Located in the heart of Mexico City, just 500 meters from the U.S. Embassy, the clinic features advanced laboratories and an experienced medical team, providing comprehensive reproductive clinical services. POWER IVF offers egg donation, sperm donation, third-party reproduction, egg freezing, in vitro fertilization (IVF), and embryo screening (PGT-A). In Mexico, IVF, gender selection, and third-party reproduction are legally available to all families—including single individuals, married couples, and LGBTQ families. Mexican regulations also permit the importation of frozen reproductive tissue (sperm, eggs, and embryos), and POWER IVF is fully licensed to receive frozen reproductive tissue from overseas, providing efficient and professional fertility solutions for patients worldwide.
