ERA – Endometrial Receptivity Analysis
A sample of the womb lining is tested to estimate when it is ready for an embryo. The evidence on its benefit is mixed, so it is used selectively.
Implantation & Endometrial Assessment
Estimating when your womb lining is ready for an embryo
ERA stands for endometrial receptivity analysis. A small biopsy of the lining is taken in a practice cycle that copies your transfer cycle. The lab studies which genes are active, to estimate whether the lining is receptive on the planned day.
When transfers keep failing, it is natural to look at timing. Large studies have not shown that ERA increases births for most women, so it is not offered routinely.
Dr Jasdev discusses whether ERA is reasonable in your case, alongside other checks that may matter more.
A plan that starts with your results
Your age, history, test results and goals are reviewed before any treatment is suggested.
Clear reasons for each step
You will know why a test or medicine is recommended, what it can do and where its limits are.
Care that stays connected
Reviews are planned around how you respond, your cycle timing and your next decision.
What ERA may offer
- Information on the timing of your implantation window
- A personalised transfer day if your timing appears shifted
- A balanced discussion of the evidence first
How your care is planned
Every stage answers three questions: what is happening, why it matters, and what comes next. The plan is reviewed at each stage and adjusted when needed.
Review past transfers and other tests
Take a biopsy in a practice hormone cycle
Adjust the transfer timing if the result suggests it
How ERA works
You take the same hormones as for a frozen transfer, but instead of a transfer, a biopsy is taken. The sample is sent to a specialist laboratory. The result shows whether the lining appeared receptive at that time, or earlier or later than expected.
Who may consider it
Women who have had several transfers of good quality embryos without a pregnancy, once other causes have been checked. It is not recommended before a first transfer.
What to expect
The practice cycle takes about two to three weeks. The biopsy is quick and causes a brief cramp. Results usually take a few weeks. Your next transfer is then planned with any timing change the result suggests.
How Dr Jasdev works with you
He brings together experience in fertility and gynaecology, and he explains things in plain language. Advice is based on current evidence and on what matters to you. You will always know what the next step is and why it has been suggested. He sees couples from Kuala Lumpur and across Malaysia, as well as some who travel from neighbouring countries.
What to bring to your appointment
Your records help Dr Jasdev understand your history quickly, so more of the visit can go to your questions. If you cannot find everything, bring what you have.
- Records of previous transfers and hormone plans
- Results of other implantation tests
- Questions about costs and evidence
What couples often ask
Most couples arrive with several questions. These common ones can help you plan what to ask.
Could the timing of transfer be the problem?
Will ERA improve our chances?
Does it delay treatment?
Are there other tests worth doing first?
Your questions about ERA
What is ERA?
Endometrial receptivity analysis is a test of the womb lining that estimates whether it is ready for an embryo on a given day.
Who is it suitable for?
Women with repeated unsuccessful transfers of good quality embryos, once other causes have been looked at. It is not a routine test.
What tests are needed first?
A womb assessment, such as a hysteroscopy, and a review of embryo quality and past transfers.
Is it painful or risky?
The biopsy causes a brief cramp and some spotting. The main drawbacks are the extra time and cost, given the mixed evidence.
Why see Dr Jasdev about ERA?
He gives a balanced view of the evidence, so you can decide whether the test is worth doing for you.
How do I book?
Call or WhatsApp the clinic to discuss your past transfers and whether ERA is appropriate.
