PGD in Georgia is a frequently searched topic by intended parents who want embryo genetic testing as part of IVF in Tbilisi. PGD (Preimplantation Genetic Diagnosis) is used to test embryos before transfer to help reduce the risk of transferring embryos affected by a specific inherited genetic condition. Many patients also see PGD discussed under the broader modern term PGT (Preimplantation Genetic Testing), but “PGD” remains a common keyword in Google searches—especially for patients looking for a practical, detailed explanation.
What Is PGD (Preimplantation Genetic Diagnosis)?
PGD is a genetic test performed on embryos created through IVF before an embryo transfer. The goal is to identify embryos that are not affected by a specific genetic disease that the parents are at risk of passing on.
PGD is typically designed for single-gene (monogenic) conditions—for example, when one or both partners are carriers of a known inherited disorder. By testing embryos before transfer, PGD supports more informed embryo selection and may reduce the risk of certain genetic outcomes.
Patients often search with phrases such as:
-

-

-

-

-

PGD vs PGT: What’s the Difference?
Many patients use “PGD” to mean any embryo genetic testing, but clinically the terminology is often grouped under PGT:
-
PGT-M: for specific single-gene inherited disorders (this is closest to traditional PGD)
-
PGT-SR: for chromosomal structural rearrangements (such as translocations)
-
PGT-A: for embryo chromosomal screening strategies in selected cases
If your main goal is avoiding a known inherited disease, your treatment plan is usually focused on PGT-M/PGD. Your specialist will clarify which test best matches your indication.
Who Should Consider PGD in Georgia?
PGD is typically considered when there is a confirmed genetic risk. Common reasons include:
1) Known Carrier Status for a Genetic Condition
If one or both partners are carriers, PGD can help identify embryos that are not affected by the condition being tested.
2) Family History of a Specific Inherited Disorder
A significant family history may prompt genetic counseling and targeted PGD planning.
3) Previous Pregnancy Affected by a Genetic Condition
Some patients consider PGD after a previous pregnancy was diagnosed with a genetic disorder.
4) Recurrent Miscarriage with Genetic Considerations
If pregnancy losses suggest a genetic factor, PGD/PGT may be discussed as part of the fertility plan.
5) Chromosomal Rearrangements
If one partner carries a chromosomal rearrangement (for example, a balanced translocation), embryo testing may be recommended to reduce the chance of transferring an embryo with an unbalanced chromosome set.
How PGD Works in Georgia (Tbilisi): Step-by-Step
PGD is performed within an IVF cycle. It is not a separate treatment; it is a laboratory and genetic testing step that guides embryo selection before transfer.
Step 1) Genetic Consultation and Test Design
A PGD plan starts with detailed review of:
-
medical history and fertility diagnosis
-
genetic reports or carrier screening results
-
family history and previous pregnancy history (if relevant)
For many single-gene conditions, a custom testing strategy may be needed. This planning step ensures the lab is testing for the right target and producing a reliable result for embryo selection.
Step 2) IVF or IVF/ICSI to Create Embryos
Embryos must be created through IVF. Many PGD cycles use ICSI to reduce the risk of contamination from extra sperm cells and support clearer genetic analysis.
Step 3) Embryo Culture and Development Monitoring
Embryos are cultured in the lab for several days. Embryologists monitor development and identify embryos suitable for biopsy.
Step 4) Embryo Biopsy (Sampling Cells for Testing)
A small number of cells are removed from the embryo at the appropriate stage by trained embryology staff. The biopsy is performed using specialized laboratory techniques designed to minimize risk to embryo development.
Step 5) Genetic Analysis of the Biopsy Sample
The biopsy sample is analyzed according to the PGD strategy, typically focused on identifying whether the embryo is:
-
affected by the condition
-
a carrier (depending on the condition and testing goal)
-
unaffected
Your team will explain how results will be categorized and how embryo selection decisions will be made.
Step 6) Embryo Transfer Planning (Often via FET)
Because genetic testing takes time, many PGD cycles plan for Frozen Embryo Transfer (FET). Embryos are often frozen after biopsy while results are finalized, then the uterus is prepared for transfer in a later cycle.
PGD and Frozen Embryo Transfer (FET) in Georgia
PGD is frequently combined with FET for practical reasons:
-
more time to complete genetic analysis
-
flexible scheduling for international travel
-
controlled endometrial preparation for transfer timing
FET planning typically focuses on creating the best uterine environment for implantation with individualized hormone support and ultrasound monitoring.
What PGD Can and Cannot Do
What PGD Can Do
-
help reduce the risk of transferring embryos affected by a specific tested condition
-
support more informed embryo selection
-
provide clarity for patients with known inherited disease risks
What PGD Cannot Do
-
guarantee pregnancy or a live birth
-
eliminate all genetic risks (it tests for specific targets)
-
replace standard prenatal care and follow-up evaluation once pregnancy is achieved
Your specialist will explain realistic expectations based on your age, diagnosis, embryo development, and uterine factors.
PGD Success Factors: What Affects Outcomes?
Even with PGD, IVF outcomes depend on multiple factors:
-
Age and ovarian reserve (egg quantity and quality)
-
Number of embryos available for testing
-
Embryo development and laboratory conditions
-
Sperm quality and fertilization method (often ICSI)
-
Uterine readiness and endometrial preparation
-
Medical factors such as fibroids, polyps, endometriosis, inflammation
-
Lifestyle factors including smoking, weight, and chronic health conditions
PGD improves embryo selection for a specific genetic goal, but overall success still depends on the complete IVF pathway.
Timeline for International Patients Seeking PGD in Georgia (Tbilisi)
International patients often want a clear schedule. While each plan is unique, a typical structure may include:
-
Pre-arrival phase:
Online consultation, medical file review, and PGD strategy planning -
IVF phase in Georgia:
Ovarian stimulation monitoring, egg retrieval, fertilization, embryo development, and biopsy -
Testing and transfer phase:
Genetic results finalize, then transfer planning (often FET) is scheduled
Because PGD often uses a frozen transfer strategy, international patients may plan either:
-
one longer stay, or
-
two shorter stays (retrieval + later transfer), depending on timing and medical preference
Common Questions About PGD in Georgia
Is PGD painful?
PGD is performed on embryos in the laboratory. The patient does not feel the biopsy process. The medical steps for the patient are the standard IVF steps (monitoring, egg retrieval, transfer).
Do all embryos survive biopsy?
Embryo biopsy is performed by trained professionals using specialized methods. As with any laboratory procedure, there are risks, but it is widely used in IVF settings when clinically indicated.
Can PGD be done for any disease?
PGD is typically designed for specific inherited conditions and requires precise planning. Not all conditions are suitable, and some require customized test development.
Will PGD reduce miscarriage risk?
In some scenarios, embryo genetic testing strategies may support better embryo selection, but outcomes depend on the underlying cause of miscarriage and the overall medical picture.
