Can You Choose Your Baby’s Sex Through Surrogacy?
November 2025
At Surrogate Mexico, one of the most frequently asked questions from people looking to build a family is: “Can I choose my baby’s sex?” And the answer is yes. Thanks to advances in reproductive medicine, it’s now possible to make more informed and personalized decisions to fulfill that desire.
Sex selection is a completely safe and scientifically supported option when performed as part of an In Vitro Fertilization (IVF) treatment, and it can be integrated into the surrogacy process. Here, we explain how it works and what you should know.
How Is the Baby’s Sex Selected Through Surrogacy?
The key lies in Preimplantation Genetic Testing (PGT), a technique that provides detailed genetic information about each embryo before it is transferred to the surrogate’s uterus.
During the IVF process, eggs and sperm are used to create embryos in a lab. These embryos are then genetically tested to identify chromosomal abnormalities and, if desired, to determine their sex.
This allows intended parents to select a male or female embryo according to their preference, offering not only more control but also the possibility of preventing sex-linked genetic diseases.
Why Do Some People Choose Their Baby’s Sex?
Choosing a baby’s sex can stem from many deeply personal and valid reasons. Some of the most common include:
- Family balance: Many people dream of having children of both sexes, and this option allows for that balance.
- Personal or cultural ties: Some families feel a special connection to a particular sex, whether due to tradition, family history, or simply preference.
- Prevention of hereditary diseases: In certain cases, sex selection also helps avoid severe genetic diseases that predominantly affect either males or females.
Whatever the reason, at Surrogate Mexico we accompany every story with respect, without judgment, and with the best available technology.
How Does the Process Work, Step by Step?
When you choose your baby’s sex as part of a surrogacy journey, the process follows these steps:
- Initial personalized evaluationA thorough medical and emotional evaluation is carried out to understand your case and design a comprehensive treatment plan.
- **Ovarian stimulation and in vitro fertilization (IVF)**Eggs are obtained from a donor and fertilized with sperm to create embryos in the lab.
- **Preimplantation Genetic Testing (PGT)**Embryos undergo genetic testing to determine their chromosomal makeup, including sex.
- Embryo selectionA healthy embryo of the desired sex is selected for transfer.
- Transfer to the surrogateThe selected embryo is transferred into the uterus of a carefully screened and approved surrogate.
- Comprehensive follow-up and supportThroughout the pregnancy, all parties receive continuous medical monitoring and emotional support.
Technology That Empowers Your Decisions
At Surrogate Mexico, we work in partnership with Ingenes, one of the most advanced fertility and genetics institutes in Latin America and a pioneer in tools such as Eligender®, a genetic analysis technology that allows for accurate and safe sex selection.
Thanks to this technology, not only can the embryo’s sex be identified, but it’s also possible to ensure the selected embryo is genetically healthy. This significantly increases the chances of a successful pregnancy and reduces the risk of hereditary diseases.
Becoming a Parent with the Freedom to Choose
Sex selection through surrogacy is especially valued by:
- Single individuals who want to have a child and have a specific preference.
- Same-sex couples who wish to share a genetic bond with their child and choose whether they’ll have a boy or girl.
- Couples who already have children and want to balance their family.
Whatever your family structure, Surrogate Mexico recognizes your right to build a family on your own terms, with the medical and ethical support of professionals who guide you every step of the way.
