How Does PGD Reduce the Transmission of Hereditary Diseases?
PGD, now referred to as PGT-M, involves analyzing small cell samples taken from embryos created during IVF for a specific single-gene disorder. This analysis assesses whether embryos carry a known genetic variant, allowing a suitable embryo to be selected for transfer to the uterus.
The method may be considered for genetically defined conditions such as cystic fibrosis, thalassemia, spinal muscular atrophy, Huntington’s disease, and certain inherited cancer predispositions. PGD may help reduce risk, but it does not guarantee pregnancy, birth, or the absence of all genetic characteristics or health conditions in the baby.
Successful planning first requires confirmation of the genetic diagnosis, identification of the genetic variant in the family, and preparation of a test specifically for that variant by the laboratory. For this reason, the process is more personalized and requires more preparation than standard embryo screening.
Genetic Safety Standards for PGT-M in Turkey
When choosing a provider in Turkey, it is important to verify whether the clinic has a Ministry of Health–approved Health Tourism Authorization Certificate and whether the embryology and genetics laboratory has the relevant licenses. Coordination between the IVF center and genetics laboratory throughout the process also supports safety in embryo identification and sample tracking.
Turkish reproductive medicine and medical genetics teams work with PGT-M for single-gene disorders, PGT-SR for structural chromosomal abnormalities, and chromosome-number testing in certain clinical situations. The appropriate test is determined according to the type of genetic variant you carry, your family history, and any previous molecular analyses.
Key Points Considered During the Evaluation
- Availability of a molecular diagnosis for the known genetic disease in the family
- Whether the genetic report is current and verifiable
- Explanation of the inheritance pattern during genetic counseling
- Suitability for IVF treatment and assessment of ovarian reserve
- Whether the PGT result needs to be confirmed with independent prenatal tests
PGT results may include different categories such as “unaffected,” “carrier,” or “affected.” For some diseases, carrier status may have mild or no clinical symptoms, while in other situations it may directly affect decisions about embryo selection; this distinction should be discussed with a genetic counselor.
What May Be Included in a PGD Package in Turkey?
As part of medical tourism planning, airport or in-city VIP transfers, accommodation, interpreter support, and coordination during the initial care period may be offered in a single package. You should confirm the scope and limitations in writing. During the preparation stage specific to PGD, the review of genetic reports, assessment of the family pedigree, required blood tests, and verification of laboratory facilities capable of performing embryo biopsy are planned.
The length of stay in Turkey depends not only on PGD but also on whether ovarian stimulation, egg retrieval, and embryo transfer will all take place during the same trip. In some plans, the initial consultation takes place online; reports and samples may need to be sent to the laboratory in advance to prepare the genetic test.
Preparation Before Embryo Testing
- English or Turkish translations of previous reports documenting the genetic disease
- Genetic test results from family members
- Reproductive history and any previous IVF results
- Ovarian reserve assessment, semen analysis, and basic infection screening
- The time required for the laboratory to prepare a customized PGT-M probe or test design
After embryo biopsy, the analysis time may vary depending on the complexity of the test. In some cases, embryos are frozen and a separate transfer cycle is planned after the results are available.
PGD Cost in Turkey and Comparison by Country
The average total cost of an IVF process including PGD in Turkey varies depending not only on the genetic analysis fee but also on medications, egg retrieval, the number of embryos, and the preparation of a test customized for the family. The ranges below are approximate international price comparisons; the actual quotation can be determined after your genetic file has been reviewed.
| Country | Approximate total cost | Currency | Main stages typically included |
|---|---|---|---|
| Turkey | €4,500–€9,000 | EUR | IVF, embryo biopsy, and limited-scope PGT-M analysis |
| United Kingdom | £12,000–£20,000 | GBP | IVF, genetic test preparation, and laboratory procedures |
| Germany | €10,000–€18,000 | EUR | Fertility treatment, biopsy, and genetic analysis |
| United States | $18,000–$30,000 | USD | IVF and family-specific embryo genetic testing |
These figures may not include travel, accommodation, interpreter services, additional freezing and storage fees, medications, additional embryo biopsies, or prenatal confirmation tests. When requesting a quotation, review the terms regarding “the number of embryos analyzed,” “test design fees,” “freezing and storage duration,” and “repeat charges in the event of an unsuccessful or insufficient result” in writing.
Factors Determining the PGD Price and Scope of the Process
- Physician expertise and experience: Collaboration between reproductive endocrinology, embryology, and medical genetics teams on the same case may affect the management of different clinical scenarios, including single-gene disorders, chromosomal translocations, and inherited cancer predispositions.
- Genetic method used: PGT-M may involve targeted molecular analysis, family-specific haplotyping, and, when necessary, NGS-based testing. PGT-SR focuses on structural chromosomal changes, while PGT-A assesses chromosome number; these tests are not automatically interchangeable.
- Number of embryos and samples: As the number of embryos analyzed increases, biopsy, laboratory, and storage costs may vary. Ask the clinic in advance how it handles insufficient DNA, mosaic results, or samples that cannot be interpreted technically.
- Clinic location: Major centers such as Istanbul, Ankara, and Izmir may offer broader laboratory access and international coordination; local transfers, accommodation, and additional travel time may affect the overall budget.
Rational Next Steps After PGD
- What is the difference between PGT-M and PGT-A, and which may be considered for my family’s genetic variant? PGT-M examines a targeted single-gene disorder, while PGT-A assesses chromosome number; whether both are needed in the same treatment plan is determined through genetic consultation.
- What confirmation is performed during pregnancy for an embryo that appears healthy based on the PGD result? Embryo testing does not replace a definitive diagnosis. After pregnancy is established, you should discuss prenatal confirmation options such as chorionic villus sampling or amniocentesis with an obstetrician and genetic specialist.
- How long does it take to prepare a family-specific PGT-M test in Turkey? The duration varies depending on the adequacy of the genetic reports, whether additional samples from family members are needed, and the laboratory’s test design for the target mutation.
When deciding on PGD, do not focus only on the number of embryos or the price quotation. Genetic counseling, laboratory quality certifications, the sample tracking system, the scope of the results report, and the follow-up plan after pregnancy should all be evaluated together.
