Before an embryo is transferred, a few cells are biopsied and screened — for chromosome number (PGT-A), for a known familial mutation (PGT-M), or for structural rearrangements (PGT-SR). China's PGT programmes are licensed and large-scale, and for families carrying hereditary disease, PGT-M means having a healthy child without rolling genetic dice.
What it treats & who qualifies
- Couples both carrying recessive mutations (thalassaemia, cystic fibrosis, sickle-cell).
- Known dominant familial diseases (Huntington's, Marfan's, familial cancer syndromes).
- Chromosomal rearrangement carriers (translocations, inversions) with recurrent loss.
- Advanced maternal age or recurrent aneuploid loss — PGT-A to lower miscarriage risk.
- Previous child affected by a testable genetic condition.
Why patients travel to China for this
- China's licensed PGT programmes cover all three modalities (PGT-A / PGT-M / PGT-SR) with large published cohorts and rapid laboratory turnaround times.
- PGT-M for monogenic disease (thalassaemia, haemophilia, Huntington's, BRCA-related syndromes) is delivered with genetic counselling in both Chinese and English.
- PGT-A adds roughly US$1,500–3,000 to a cycle in China, versus US$4,000–7,000 in the US.
Treatment options, compared
| Option | Best suited for | What it means in practice |
|---|
| PGT-M (monogenic) | Known familial mutations | Custom probe design; works for rare variants — feasibility answered before you pay. |
|---|
| PGT-A (aneuploidy) | Age-related risk, recurrent loss | Euploid-only transfer lowers miscarriage substantially. |
|---|
| PGT-SR (structural rearrangements) | Translocation carriers | Balanced-embryo selection. |
|---|
The procedure, step by step
- Genetic counselling reviews your family history and previous testing; a testing strategy is agreed.
- IVF cycle proceeds to blastocyst stage (day 5–6); a 5-cell trophectoderm biopsy is taken.
- Embryos are vitrified while the biopsy is analysed (array CGH, NGS, or mutation-specific testing).
- Results arrive in 1–3 weeks: affected, carrier, unaffected, or aneuploid status per embryo.
- A euploid / unaffected embryo is transferred in a frozen cycle; the rest remain stored.
Cost, hospital stay & recovery
| Typical China cost (reference only) | US$1,500–3,000 on top of the IVF cycle cost (PGT-M test design can add more for rare mutations) |
|---|
| Typical in-hospital stay | Outpatient; embryo transfer happens weeks after biopsy results |
|---|
| Return-to-travel timeline | Two trips: ~2 weeks for retrieval + biopsy, then ~1 week for the frozen transfer (or stay between) |
|---|
Costs are indicative ranges for international self-pay patients at major Chinese hospitals; final quotes depend on the hospital, implant/medication choice and case complexity. WellVoyage locks a written all-in quote before you commit.
Recovery, week by week
- Cycle 1–2: IVF to blastocyst; biopsy on day 5–6; embryos vitrified.
- Lab window: Results in 1–3 weeks; report categorises every embryo.
- Transfer: Best unaffected/euploid embryo in a prepared frozen cycle.
- Pregnancy: Standard prenatal care at home with the genetic report in your file; prenatal confirmation testing remains routine.
Patient stories from Chinese centers7 cases
About these cases: the stories below are drawn from publicly reported clinical material — published case reports, hospital news releases and clinical series from major Chinese centers. Names and identifying details have been changed or omitted. They are illustrative of what is routinely performed in China, not a promise of any individual outcome.
A 35-year-old woman from the United States, a cystic-fibrosis carrier
She and her husband are both carriers of the same gene. PGT-M in Guangzhou tested embryos for their exact variants; the transferred embryo is a carrier of neither, and their son breathes easily.

A 33-year-old woman from the United Kingdom with a balanced translocation
Five miscarriages before karyotyping found the rearrangement. PGT-SR in China selected a balanced embryo; the pregnancy that followed is her longest, and it ended in a delivery.
Source: Hospital-reported translocation case; anonymised.
A 37-year-old couple from Italy with recurrent loss
Repeated early losses and a home clinic offering sympathy. PGT-A in Shanghai showed most of their embryos were aneuploid — an answer, not a comfort, but the first euploid transfer stuck.
Source: Public clinical reports; anonymised.
A couple from Saudi Arabia carrying thalassaemia
Both carriers of the same haemoglobinopathy. PGT-M in Beijing tested embryos for the family's specific mutation; their daughter was born free of the disease their extended family knows too well.
Source: Published Chinese haemoglobinopathy PGT series; anonymised.
A 31-year-old woman from Qatar after a chromosomally abnormal pregnancy
A prior trisomic loss made every subsequent positive test a vigil. PGT-A in China let her transfer a tested euploid embryo; the nine months that followed were anxious, but ordinary-anxious.
Source: Hospital-reported PGT-A case; anonymised.
A 38-year-old woman from Egypt with advanced maternal age
At 38 the arithmetic of chromosomes turns unfriendly. PGT-A in Guangzhou screened her batch; two euploid embryos from four biopsied, and the first transfer succeeded.
Source: Public clinical reports; anonymised.
A 32-year-old woman from Indonesia with a family genetic history
A rare familial condition in her family tree. Pre-test work-up in China built a custom PGT-M assay for the family variant; their embryo was tested negative for it.

Frequently asked questions
Does PGT guarantee a healthy baby?
It dramatically lowers — not eliminates — the tested risks. PGT-A reduces miscarriage from aneuploidy; PGT-M prevents the tested familial disease. Prenatal testing in pregnancy remains standard practice, and the Chinese counselling sessions say so explicitly.
We carry a rare mutation — can you still test for it?
Usually yes: PGT-M test design (haplotyping) works for rare variants, and Chinese PGT labs handle unusual cases routinely. Send your family's genetic reports — the lab's feasibility answer comes back before you pay anything.
