Real Consultation Scenario: Patient Enters Clinic with Karyotype Report
A 38-year-old woman with two miscarriages carries a balanced chromosomal translocation. She asks: "Doctor, I heard that Gagua Hospital in Georgia can perform embryo genetic testing. Is that true? Which type do I need?"
Can Gagua Hospital Perform Embryo Genetic Testing?
Yes. Gagua Hospital (Gagua Reproductive Center) offers preimplantation genetic testing (PGT), including:
- PGT-A (Aneuploidy Screening): For advanced maternal age, recurrent implantation failure, recurrent miscarriage.
- PGT-M (Monogenic Disease Testing): For carriers of known pathogenic gene mutations, such as thalassemia, cystic fibrosis, etc.
- PGT-SR (Structural Rearrangement Testing): For carriers of balanced translocations, Robertsonian translocations, etc.
However, conditions must be met: embryos must be cultured to the blastocyst stage, biopsy reports are issued by partner genetic laboratories (e.g., Embryolab, GENOMA), and the cycle takes approximately 5-7 days.
Why Is There a Misconception That It "Cannot Be Done"?
Some patients confuse PGT with "embryo sex selection." Georgian law permits PGT for medical indications but prohibits non-medical sex selection. Additionally, some agencies claim "all hospitals do it," but in reality, Gagua Hospital advises patients with low egg counts or low blastocyst formation rates to accumulate embryos first; otherwise, there may be no viable embryos after biopsy.
Decision-Making Logic from a Doctor's Perspective
Reproductive center doctors first evaluate:
- Indications: Confirm chromosomal abnormalities, genetic disease risk, or recurrent failure history. PGT is not recommended without indications, as biopsy may damage embryos.
- Embryo Quantity: At least 3-5 blastocysts are needed for clinically meaningful biopsy; otherwise, there is a risk of "no embryos available for transfer."
- Lab Accreditation: Biopsy doctors at Gagua Hospital must be trained by the European Society of Human Reproduction and Embryology (ESHRE), and partner labs must be ISO 15189 certified.
Differences Among Patient Groups
| Patient Group | Suitable PGT Type | Key Considerations |
|---|---|---|
| Women ≥35 years | PGT-A | Embryo aneuploidy rate increases with age; sufficient blastocysts needed |
| Monogenic disease carriers | PGT-M | Both partners' gene loci must be identified; genetic counseling first |
| Balanced translocation carriers | PGT-SR | Simultaneous PGT-A recommended to exclude other aneuploidies |
| Recurrent implantation failure | PGT-A + Endometrial Receptivity Analysis (ERA optional) | PGT does not replace endometrial factor investigation |
Actual Process and Timeline
Step 1: Preparation (1-2 months)
- Couple's karyotype analysis, genetic counseling.
- Female: AMH, hormone panel (day 2-4), antral follicle count via ultrasound.
- Male: Semen analysis (sperm DNA fragmentation test if needed).
- Infectious disease screening (Hepatitis B, HIV, syphilis, etc.).
Step 2: Ovarian Stimulation and Egg Retrieval (approx. 2 weeks)
Procedure is identical to conventional IVF, but advance confirmation of PGT scheduling at the hospital is required.
Step 3: Embryo Culture and Biopsy (5-7 days after egg retrieval)
Blastocysts are biopsied and immediately frozen. Biopsied cells are sent for testing. Genetic results are available in approximately 5-7 working days; expedited service (2-3 days) incurs an additional fee.
Step 4: Transfer Decision
Based on the report, doctors select euploid/normal embryos for transfer. If no transferable embryos are available, a new cycle or consideration of egg/sperm donation may be needed.
Factors Affecting Cost
PGT costs at Gagua Hospital are not fixed; main variables include:
- PGT Type: PGT-A approx. $800-1,200 per embryo; PGT-M/PGT-SR require custom probes, costing approx. $2,500-4,000 per embryo (including probe development fee).
- Number of Biopsied Embryos: Some labs charge a base price for the first embryo with discounts for subsequent ones.
- Partner Laboratory: Genoma Genetics (Israel) is more expensive than local labs but has stricter quality control standards.
Easily Overlooked Details
- Genetic counseling must be done in advance: Gagua Hospital requires patients to complete genetic counseling before starting a cycle; otherwise, PGT-M/PGT-SR cannot proceed.
- Embryo freezing time after biopsy: Freezing duration may be extended; confirm embryo thaw survival rate (typically >95%).
- Legal documents: Georgian law requires both partners to sign informed consent, explicitly stating PGT is for medical purposes only.
Common Pitfalls
- "Guaranteed success" claims: No PGT can guarantee 100% normal; mosaic embryos may still be missed.
- Confusing PGT with "third-generation IVF": Some agencies blur the lines. Gagua Hospital clearly states PGT screens existing embryos and cannot improve egg quality or endometrial lining.
- Ignoring male factors: Advanced age, obesity, smoking, etc., increase sperm DNA fragmentation. Even with normal PGT, miscarriage rates may remain elevated.
Special Case: What If No Embryos Are Available for Biopsy?
If only 1-2 blastocysts are obtained after stimulation, doctors typically recommend:
- Freeze the blastocysts, then undergo 2-3 additional egg retrieval cycles to accumulate 4-5 blastocysts before unified biopsy.
- Or forgo PGT and proceed with direct transfer, but with full informed consent regarding risks.
Frequently Asked Questions
- Q: How accurate is PGT at Gagua Hospital? Biopsy of 5-8 trophectoderm cells yields ~95-98% accuracy, but may miss mosaicism (when <20% mosaic).
- Q: How many times do I need to travel to Georgia? At least twice: first for evaluation and record setup (1-2 days), second for stimulation + egg retrieval (10-12 days). Transfer requires an additional 3-5 days.
- Q: Do I need to prepare before ovarian stimulation? Routine supplementation with CoQ10 and vitamin D is advised, but no evidence shows it alters embryo chromosomal status.
Practitioner's Observation
As a reproductive doctor, I have seen many patients travel to Georgia directly after hearing "Gagua can do genetic testing," only to find insufficient embryos and have to abandon the plan. I recommend completing a basic evaluation at a local hospital first, then consulting Gagua Hospital doctors online to confirm at least 3 blastocysts can be obtained before proceeding. Additionally, PGT-M requires a probe-building process that takes at least 2 months of preparation; do not expect it to be done on the day of arrival.
Special Population Reminder: For male carriers of Y-chromosome microdeletions, sex selection via PGT is not recommended, as the microdeletion will be passed to male offspring. Genetic counseling is advised first to assess suitability for PGT-SR.
