Genetic Study of Embryos
What is the Genetic Study of Embryos?
The Preimplantation Genetic Study for Aneuploidies (PGTA) is an advanced technique that allows embryos to be analyzed before their transfer to the uterus to identify possible chromosomal abnormalities. This test ensures that only the healthiest and most viable embryos are selected for implantation, increasing the chances of a successful pregnancy and reducing the risk of miscarriages and genetic diseases.
What is the process like?
1. In Vitro Fertilization (IVF)
The eggs are fertilized with sperm in the laboratory, and the resulting embryos are cultured for a few days.
2. Embryo Biopsy
A biopsy is performed on the developing embryo, removing a few cells from the embryo without damaging it. These cells are evaluated by a geneticist to analyze chromosomes and rule out possible genetic diseases before transfer to the uterus.
3. Genetic Analysis
The extracted cells are analyzed to identify possible aneuploidies (chromosomal abnormalities) and other genetic conditions. Only genetically normal or euploid embryos are considered for transfer.
4. Transfer of Selected Embryos:
Healthy embryos identified through PGTA are transferred to the woman's uterus, significantly increasing the chances of a healthy pregnancy.

When is it recommended?
The PGTA is especially useful in the following cases:
- Women of advanced maternal age (over 35 years)
- History of recurrent miscarriages
- Repeated failures in IVF treatments
- Known genetic problems in the family
- Male factors of severe infertility

Answers to Your Questions
Although PGTA significantly increases the chances of a successful pregnancy by selecting the genetically healthiest embryos, it cannot guarantee it. Factors such as the quality of the embryo, the receptivity of the uterus and the general health of the mother also influence the success of the pregnancy.
The PGTA mainly detects aneuploidies, which are chromosomal abnormalities such as Down syndrome, Turner syndrome, and Klinefelter syndrome, among others. It cannot detect all genetic diseases, especially those caused by specific genetic mutations, for which other tests are required.
Yes, the PGTA is a safe procedure. The biopsy is performed at the blastocyst stage, when a few cells are removed from the outer layer of the embryo, without affecting its ability to develop. Studies have shown that there is no significant negative impact on embryos that undergo biopsies for PGTA.
Embryos with chromosomal abnormalities are generally not transferred due to the risk of implantation failure, miscarriage, or genetic diseases. Future parents can decide what to do with these embryos after receiving genetic counseling.
PGTA is recommended for couples with a history of recurrent miscarriages, previous IVF failures, advanced maternal age, severe male infertility, or a family history of genetic abnormalities. It is a valuable option for those who want to maximize the chances of a healthy pregnancy.
Our Patients
After many failed IVF attempts, Dr. Amezquita recommended genetic study of embryos. The difference was clear. Thanks to PGTA, we had a successful pregnancy and today we hold our baby in our arms.
The PGTA gave us the confidence we needed to proceed with our IVF treatment. Knowing that we were selecting the healthiest embryos made all the difference. We are very grateful to Dr. Amezquita for guiding us through this process.
After several miscarriages, we decided to perform PGTA to ensure the health of our embryos. Thanks to this study and Dr. Amezquita's team, today we have our beautiful daughter with us. We feel blessed and calm.
