    No position

    Not addressed in the 2021 ISAR add-ons consensus.

  • Cochrane

    Evidence base

    RCTs show no improvement in live birth from timing transfers this way.

Typical cost in India

~₹35,000–55,000, plus a delayed/extra frozen cycle.

Should I have an ERA test?
The evidence does not support it. HFEA rates it red, NICE says do not offer it (2026), and randomised trials show no improvement in live birth from timing transfers this way.
