Achieving a successful IVF pregnancy requires two essential components: a genetically healthy embryo and a receptive uterine lining. Frequently, transfer cycles fail despite using high-grade blastocysts. To resolve this clinical barrier, Prof. (Dr.) Abha Majumdar utilizes Endometrial Receptivity Analysis (ERA). This advanced molecular diagnostic tool maps the exact timeline when your uterus is ready to accept an embryo, maximizing your transfer success.
The endometrium is a dynamic tissue layer that becomes receptive to embryo attachment for only a very brief period during the menstrual cycle. This limited timeframe is medically termed the Window of Implantation (WOI). In approximately 70% of women, this window occurs at a standard, predictable time. However, remaining populations exhibit displaced timing patterns.
Furthermore, transferring a viable embryo outside of this personalized window leads to implantation failure. An asynchronous timeline prevents the embryo from signaling the uterine wall effectively. Consequently, performing an ERA test allows clinicians to discover your exact genetic timeline before risking precious frozen embryos.
Professor’s Medical Insight: We do not recommend the ERA test as a routine screening for every first-time IVF patient. Instead, we save this advanced tool for couples facing Recurrent Implantation Failure (RIF). Identifying a displaced window saves emotional stress and optimizes subsequent frozen cycles.
The ERA procedure mimics an actual Frozen Embryo Transfer (FET) cycle, but without placing a real embryo inside the womb. The entire process follows a strict diagnostic sequence:
| Protocol Stage | Clinical Action & Procedure | Target Objective |
|---|---|---|
| Hormonal Priming | The patient receives structured estrogen and progesterone doses to prepare the uterine lining tissue. | Simulates an exact embryo transfer environment. |
| Endometrial Biopsy | A clinician performs a quick, minor outpatient biopsy exactly 120 hours after starting progesterone. | Harvests a tiny tissue sample safely. |
| Genetic Sequencing | The laboratory analyzes the expression patterns of 248 specific genes within the sample cells. | Determines if the lining is Receptive or Non-Receptive. |
If the final molecular report marks the tissue as Non-Receptive, the system identifies the shift direction. The results will indicate whether the window is pre-receptive or post-receptive. Therefore, our medical team shifts the timing of your progesterone administration forward or backward for your actual transfer.
Because the test requires an invasive biopsy and additional laboratory costs, we apply strict selection criteria. Specifically, the ERA test provides the highest diagnostic value for the following patient profiles:
Once the ERA laboratory delivers your custom timing metrics, we transition to a Personalized Embryo Transfer (pET). This protocol adjusts your medication schedule to match your unique genetic window precisely. Clinical data confirms that aligning the transfer timing significantly elevates live birth rates in patients with previous failures.
Ultimately, advanced reproductive diagnostics remove guesswork from the implantation process. By combining state-of-the-art genetic sequencing with compassionate clinical management, we help you navigate complex fertility challenges safely and predictably.
