ERA Test (Endometrial Receptivity Analysis) in Hyderabad | Sanjeevini Hospital

Understanding The Test

What Is ERA?

ERA, or Endometrial Receptivity Analysis, is a specialised genetic test that examines the lining of the uterus (endometrium) to determine the most receptive day for embryo implantation — often called the "window of implantation." Every woman's window can occur at a slightly different point in her cycle, and even a shift of a day or two can affect whether an embryo implants successfully.

By analysing the expression of hundreds of genes linked to endometrial receptivity, the ERA test tells us whether your endometrium is receptive, pre-receptive, or post-receptive at the time of biopsy — allowing our fertility specialists to personalise the exact timing of your embryo transfer for the best possible chance of implantation.

Is This Right For You?

When May ERA Be Considered?

ERA testing is especially useful in specific fertility treatment situations. Here are some of the most common reasons our specialists recommend it.

Recurrent Implantation Failure

Women who have had multiple failed embryo transfers despite good-quality embryos may benefit from identifying their true implantation window.

Unexplained IVF Failure

When no clear cause is found for previous unsuccessful IVF or FET cycles, ERA can rule out timing as a contributing factor.

Before Frozen Embryo Transfer

Couples planning a frozen embryo transfer (FET) may choose ERA proactively to optimise timing from the very first attempt.

Using Donor Eggs or Embryos

Since donor-egg or donor-embryo cycles are often high-investment attempts, precise transfer timing can add an extra layer of confidence.

After PGT-Tested Embryos

When transferring a single genetically normal (euploid) embryo, ensuring the timing is precise helps make the most of that one embryo.

Personalised Treatment Planning

Some patients simply prefer a data-driven approach to embryo transfer timing rather than relying on standard protocol days.

The Process

How ERA Works

A step-by-step look at the ERA testing process at Sanjeevini Hospital, from cycle preparation to a personalised transfer plan.

Step One

Consultation & Cycle Planning

Your fertility specialist reviews your treatment history and plans a mock cycle that mirrors the hormonal preparation you would follow for a real embryo transfer.

Step Two

Hormonal Preparation

You take oestrogen and progesterone, following the same protocol timing planned for your future frozen embryo transfer, so the endometrium develops naturally.

Step Three

Endometrial Biopsy

On the day equivalent to your planned transfer day, a small, quick tissue sample is taken from the endometrial lining — a brief procedure usually completed within minutes.

Step Four

Laboratory Gene Analysis

The tissue sample is sent to a specialised genetics lab, where expression of hundreds of receptivity-related genes is analysed using next-generation sequencing.

Step Five

Receptivity Report

The lab generates a report classifying your endometrium as receptive, pre-receptive, or post-receptive at the time of biopsy, along with a recommended adjustment in hours or days.

Step Six

Personalised Transfer Plan

Your fertility specialist uses the report to schedule your next embryo transfer at the precise, personalised day of your implantation window.

Reading Your Report

Understanding the Results

Your ERA report translates complex gene-expression data into a clear, actionable recommendation for your next embryo transfer.

Receptive: Your endometrium was receptive at the time of biopsy — your standard transfer-day timing is likely ideal.
Pre-Receptive: The window occurs later than tested — progesterone exposure is extended before your next transfer.
Post-Receptive: The window occurs earlier than tested — progesterone exposure is shortened before your next transfer.
Personalised pET: Your future frozen embryo transfer (pET) is scheduled using this adjusted timing for a receptive endometrium.
Specialist Review: Our fertility team walks you through your report in detail and answers all your questions before your next cycle.

Quick Answers

Frequently Asked Questions

The most common questions patients ask about the ERA test at Sanjeevini Hospital.

The endometrial biopsy involved in the ERA test is similar to a Pap smear or IUI procedure. Most women feel brief cramping during the sample collection, which resolves quickly afterward.

Results are typically available within a couple of weeks after the biopsy, depending on the laboratory processing the gene-expression analysis.

No. Once your personalised window of implantation is identified, that same timing is generally used for future transfers, so repeat ERA testing usually isn't required.

Not necessarily. ERA is most valuable for women with recurrent implantation failure or unexplained IVF failure, though some patients opt for it proactively. Your specialist will advise if it's right for your case.

By identifying the precise window of implantation, ERA helps ensure your embryo is transferred at the most receptive time, which can improve implantation chances for women with a shifted window.
