PGT-A (preimplantation genetic testing for aneuploidy)
A biopsy of the embryo to check it has the right number of chromosomes before transfer.
Written by Fertility Decoded. Reviewed by D R, MS (OBG), FRM. Review date: 31 August 2026.
The verdict
Not recommended as a routine add-on; it may reduce your chance of a baby (especially under 35), though it can reduce the chance of miscarriage.
Who are these bodies?
- HFEA
- — UK fertility regulator; rates add-ons by evidence (traffic-light).
- ESHRE
- — European fertility society; evidence-based practice guidance.
- NICE
- — UK health-guidance body; what the NHS will and won't fund.
- ISAR
- — Indian Society for Assisted Reproduction; Indian expert consensus.
- Cochrane
- — Independent global reviewers of the underlying studies.

UK NHS guidance
Do not offer (2026)NG257 1.48.1: do not offer PGT-A as part of fertility treatment to improve live birth rates.

Indian society
Role for age 36–40 & known-cause RPLISAR PGT consensus: recommended for advanced maternal age (36–40) and repeated pregnancy loss with a known cause; not recommended for under-35 good-prognosis, unexplained RPL, or low-AMH patients; no evidence of efficacy in recurrent implantation failure.

Evidence base
2020 review: insufficient evidence of a difference in cumulative live birth; possible miscarriage reduction on the first transfer only, cumulative data scarce.
Typical cost in India
~₹23,000–30,000 per embryo (some clinics ₹25,000–50,000+ total), on top of base IVF.
- For most patients, no. HFEA rates it red for improving your chance of a baby because it is a selection tool that reduces the embryos available and can lengthen the time to conception; NICE advises not offering it to improve live birth rates.
- It can reduce the chance of miscarriage (HFEA rates it green for that), and the Indian society (ISAR) sees a role for women aged 36–40 or with known-cause recurrent pregnancy loss. It is not recommended for younger, good-prognosis patients.
