Starting Price

The ERA (Endometrial Receptivity Assay) test at Kanaa Fertility is a genetic test that checks whether your endometrial lining is ready to accept a fertilised embryo — helping identify the exact right day for transfer. Two clinics in KK Nagar & Mylapore, with in-person & online consultations.

WHAT IS ERA

ERA — Finding Your Best Day for Transfer

A genetic test that checks whether your endometrial lining is ready to receive an embryo.

This is a genetic test performed to assess the readiness of the endometrial lining to accept the fertilised embryo.

It tests around 236 genes identified as important for implantation to occur.

Personalised Timing

Finds the specific day your lining is most ready, rather than assuming a standard timeline.

Genetic, Not Guesswork

Based on analysis of your own tissue sample, not a general estimate.

Prepared Like a Real Transfer

Your cycle is prepared exactly as it would be for an actual frozen embryo transfer, so results reflect your real situation.

THE PROCEDURE

What Happens During an ERA Test

Your cycle is prepared exactly as it would be for a real frozen embryo transfer.

Endometrial Preparation

Your lining is prepared exactly as it would be for an actual frozen embryo transfer.

Progesterone Course

Once your lining reaches a satisfactory thickness, progesterone injections are given for five to six days.

Endometrial Biopsy

One day after the progesterone course ends, a biopsy of the lining is taken in the OPD.

Genetic Analysis

The sample is sent for analysis of around 236 genes linked to implantation readiness.

Medical Report

You receive a report indicating whether your lining was receptive at that point in your cycle.

Transfer Programmed for the Optimum Day

Your actual embryo transfer is then timed to the day your results show your lining is most receptive.

WHEN IS IT NEEDED

When Is an ERA Test Recommended?

This isn't advised for everyone — your specialist will advise if it's right for you.

Previous Unexplained Implantation Failure

When embryo transfers haven't succeeded despite good-quality embryos.

Before a Repeat Frozen Embryo Transfer

To help personalise timing for future attempts.

As Recommended by Your Specialist

Since ERA isn't needed for everyone, your doctor will advise if your situation calls for it.

WHAT'S INVOLVED

What's Involved in This Visit

An ERA test involves a preparation cycle (similar to a real frozen embryo transfer), a progesterone course, and a biopsy taken in the OPD. Starting price to be confirmed by the clinic.

RISKS & WHAT TO EXPECT

Risks & What to Expect

Common and usually mild

Mild discomfort or cramping during the biopsy
Light spotting afterward

Less common, worth knowing

Infection — Uncommon, similar to other procedures involving a tissue sample.
A "Not Receptive" Result — This isn't a failure — it simply means your transfer timing needs adjusting, which is exactly what this test helps with.

Please let us know about any concerns beforehand — we're here to make this as comfortable as possible.

FAQ

Frequently Asked Questions

How is it reported?

The report is usually given as receptive or non-receptive. If non-receptive, it may be pre-receptive (meaning the timing is too early and the transfer needs to be delayed) or post-receptive (meaning the timing is too late and the transfer needs to be advanced).

Is it advised for everyone?

No — this isn't needed for everyone. Your specialist will advise whether it's right for your specific situation.

How long does it take to get results?

Results typically take some time to process after your biopsy — your specialist will let you know when to expect them.

Is the biopsy painful?

Most women experience mild discomfort or cramping, similar to other endometrial biopsy procedures.

Will I need to repeat the test?

This depends on your results and your specialist's recommendation for your specific situation.
