Third-Generation IVF (PGT)

Screen 200+ genetic diseases before embryo transfer. Achieve up to 98% success rate with the world's most advanced genetic testing technology.

What is Third-Generation IVF (PGT)?

Preimplantation Genetic Testing (PGT) is one of the most advanced assisted reproductive technologies available today. Building on traditional IVF, it adds a genetic screening step before embryo transfer — allowing doctors to select only chromosomally normal, disease-free embryos for transfer.

The core advantage: PGT can screen for 200+ genetic diseases with a success rate of up to 98%, significantly reducing miscarriage risk and improving implantation rates.

Three Types of PGT Testing

Your doctor will recommend the most suitable testing plan based on your specific situation.

PGT-A

Chromosomal Screening

Aneuploidy Screening

Detects whether the embryo has the correct number of chromosomes (normal: 23 pairs, 46 total). Chromosomal abnormalities are the leading cause of recurrent miscarriage and IVF failure.

  • ✓ 99%+ aneuploidy detection
  • ✓ Significantly reduces miscarriage risk
  • ✓ Improves IVF success rate
PGT-M

Single Gene Testing

Monogenic Disease Screening

Precisely screens embryos for known single-gene hereditary diseases.

  • ✓ Thalassemia
  • ✓ Spinal Muscular Atrophy (SMA)
  • ✓ Cystic Fibrosis
  • ✓ Hemophilia
PGT-SR

Structural Variation

Chromosomal Structural Abnormalities

Detects chromosomal structural abnormalities such as balanced translocations and inversions. Suitable for patients with recurrent miscarriage or family history of chromosomal abnormalities.

  • ✓ Balanced translocation screening
  • ✓ Inversion detection
  • ✓ Robertsonian translocation

Frequently Asked Questions

What is the difference between PGT and traditional IVF? +
Traditional IVF transfers embryos without genetic screening, while PGT adds a genetic testing step before transfer to select only chromosomally normal embryos. This significantly reduces miscarriage risk and improves success rates, especially for women over 35.
How long does the entire PGT process take? +
The complete PGT process typically takes 2-3 months, including initial consultation, medical examination, ovarian stimulation, egg retrieval, genetic testing, and embryo transfer.
What is the success rate of PGT? +
Vivia IVF's PGT success rate is up to 98%. The actual success rate depends on individual factors such as age, egg quality, and uterine conditions.
Is PGT safe? Will it harm the embryo? +
PGT is a mature and safe technology. The biopsy procedure takes only 1-2 cells from the embryo (typically at the blastocyst stage), which does not affect the embryo's development potential.
What diseases can PGT screen for? +
PGT-A can screen for chromosomal aneuploidies; PGT-M can screen for 200+ single-gene diseases including thalassemia, SMA, and cystic fibrosis; PGT-SR detects chromosomal structural abnormalities.
