10 Key Questions About PGT-A — Your Path to a Successful Pregnancy at Reproart
🌟 At Reproart, we are committed to providing the highest standards of reproductive medicine, supported by advanced technology, a state-of-the-art in-house genetic laboratory accredited by GENQA and certified under ISO 9112:2015 and a dedicated team of experts. Our goal is to optimize your chances of success and help turn your dreams of parenthood into reality.
One of the most groundbreaking tools we utilize is Preimplantation Genetic Testing for Aneuploidy (PGT-A) — a process that screens embryos for chromosomal abnormalities, ensuring that only healthy, chromosomally normal embryos are transferred.
If you are exploring your options or are curious about how PGT-A can improve your IVF outcomes, here are the 10 most important questions answered:
Q1: What is PGT-A?
🧬 PGT-A is a preimplantation genetic test conducted in our GENQA and ISO9001:2015 certified in-house genetic laboratory. It screens embryos for chromosomal abnormalities (aneuploidies), helping us select the most viable embryo for transfer.
Q2: When during IVF is PGT-A performed?
🕒 The test is performed when the embryo reaches day 5 of development, once it has attained a suitable stage for biopsy.
PGT-A is typically performed on day 5, 6, or sometimes day 7 of embryo development – when the embryo reaches the blastocyst stage.
Q3: Who should consider PGT-A?
👩🔬 PGT-A may be especially helpful for patients who are over 35, have experienced multiple miscarriages, failed IVF cycles, or have concerns about chromosome-related conditions. It helps identify embryos with the correct number of chromosomes, which can improve the chances of a healthy pregnancy and reduce the risk of miscarriage.
Q4: How much does PGT-A improve pregnancy chances?
🚀 PGT-A can help improve your chances of pregnancy by identifying embryos with the correct number of chromosomes, especially if you are over 35 and have multiple embryos available. In women aged 35 to 40, using PGT-A can increase implantation rates to around 60–70% per transfer, compared to 40–50% without it. It also reduces the risk of miscarriage to about 5–10%, while without PGT-A, miscarriage rates in this age group can be as high as 20–30%. While PGT-A does not improve embryo quality, it helps your doctor select the healthiest embryo, giving you a better chance of a successful pregnancy and reducing the emotional and physical toll of repeated IVF attempts.
Q5: How is the embryo biopsy performed and is it safe?
🔬 Embryo biopsy is the clockwork process that requires both state-of-the-art equipment and experienced hands. At Reproart, the embryo biopsy is performed with the highest level of precision using advanced laser technology and carried out by our highly qualified embryologists. On the third day of development, a tiny opening is made in the outer shell of the embryo using a specialized laser. This step prepares the embryo for a safe biopsy later on. By the fifth or sixth day, when the embryo reaches the blastocyst stage, a few cells are carefully taken from the trophectoderm - the outer layer that will eventually form the placenta, without touching the part that becomes the baby, so the procedure does not harm the developing embryo. The sampled cells are then analyzed in Genomics, our in-house genetic laboratory, while the embryo is safely frozen.
Q6: What results indicate a healthy embryo?
✅ In PGT-A, a healthy embryo is one that is euploid – meaning it has the correct number of chromosomes (46 total, or 23 pairs), which gives it the best chance to implant, grow into a healthy baby, and reduce the risk of miscarriage.
Embryos labeled as “aneuploid” (abnormal number of chromosomes) or “mosaic” (a mix of normal and abnormal cells) are generally not recommended for transfer, though some mosaic embryos may still be considered after genetic counseling, depending on the specifics.
Q7: How long does the genetic testing take?
⏱️ After biopsy, the sample is sent to our in-house laboratory and results are typically available within 10 working days.
Q8: Are there risks involved in PGT-A testing?
⚠️ PGT-A is considered a safe and low-risk procedure when performed by experienced professionals, but like any medical procedure, it carries a few small risks — including potential damage to the embryo during biopsy (though this is rare), the possibility of not having any embryos suitable for testing or transfer, and the chance of uncertain or inconclusive results. Additionally, if the temperature is not properly maintained during sample transportation, it could affect the accuracy of the analysis. To minimize these risks, Reproart conducts all PGT-A testing in our dedicated in-house laboratory, Genomics in Tbilisi, ensuring full control over the process and providing our team and patients with precise, timely, and reliable diagnostic services.
Q9: Can PGT-A be performed on frozen embryos?
❄️ Yes – PGT-A can be performed on previously frozen embryos. The embryo is carefully thawed, a small number of cells are taken once it reaches the blastocyst stage, and then it is safely refrozen while waiting for results. This approach is safe and widely used, especially when patients decide to test embryos created in earlier IVF cycles. Hower, the process itself requires delicate handling, and our experienced team at Reproart ensures it is done safely and reliably, giving you peace of mind.
Q10: What is the main benefit of PGT-A?
🎯 The main benefit of PGT-A is that it helps identify embryos with the correct number of chromosomes, which gives them the best chance to implant successfully, reduce the risk of miscarriage, and increase the chances of a healthy pregnancy.
At Reproart, quality is not just a standard — it is our signature.
