Endometrial Receptivity Analysis (ERA)
WHAT IS ENDOMETRIAL RECEPTIVITY ANALYSIS (ERA)
Endometrial Receptivity Analysis (ERA) is a specialized diagnostic test used to determine the most optimal time for embryo transfer by analyzing the receptivity of the uterine lining. It helps identify the “window of implantation” when the uterus is most prepared to accept an embryo.
At Freya Fertility, ERA is used to personalize embryo transfer timing, especially in patients with repeated IVF failures or implantation issues.
ERA is beneficial for patients who:
- Have recurrent implantation failure
- Have experienced repeated IVF failures
- Have good-quality embryos but no pregnancy
- Have unexplained infertility
- Want a personalized embryo transfer approach
WHAT IS ERA TEST?
ERA is a molecular test performed on a small sample of the endometrial lining to evaluate gene expression and determine whether the uterus is receptive at a specific time. It helps doctors adjust the timing of embryo transfer for better implantation success.
Initial Assessment & Cycle Planning
A mock cycle is planned to simulate the conditions of an actual embryo transfer.
Endometrial Preparation
Hormonal medications are used to prepare the uterine lining.
Endometrial Biopsy
A small tissue sample is taken from the uterus at a specific time.
Molecular Analysis
The sample is analyzed to assess gene expression and receptivity status.
Personalized Embryo Transfer (pET)
Based on ERA results, the exact timing for embryo transfer is determined.
Embryo Transfer & Follow-Up
Embryo transfer is performed at the optimal time, followed by monitoring and care.

FAQs
What is ERA test in IVF?
It is a test that determines the best time for embryo transfer by analyzing uterine receptivity.
Who should consider ERA?
Patients with repeated IVF failures or implantation issues benefit the most.
Is ERA painful?
The biopsy may cause mild discomfort but is generally well tolerated.
Does ERA guarantee pregnancy?
No, but it significantly improves the chances by optimizing transfer timing.
Is ERA done in every IVF cycle?
No, it is usually recommended in specific cases like recurrent implantation failure.
