Introduction: When Good Embryos Still Do Not Implant
Some couples have healthy-looking embryos and well-timed transfers, yet pregnancy does not happen. After repeated disappointment, a natural question is whether something hidden in the uterus is getting in the way.
One condition doctors sometimes consider is chronic endometritis, a low-grade inflammation of the uterine lining that may cause few or no symptoms. At ReproArt Fertility, the Best IVF Centre in Noida, we believe couples deserve a clear and honest explanation: what the condition is, how it is tested, what the evidence says, and when testing makes sense.
This guide from our IVF Doctor in Noida team is general information, and it is important to read it with one point in mind. Research on this topic is still developing, so decisions should always be individual.
What Is Chronic Endometritis?
The endometrium is the inner lining of the uterus, where an embryo must attach and grow. Chronic endometritis (CE) means this lining has long-standing, low-grade inflammation, most often linked to bacteria. It is different from acute infections that cause fever and severe pain, and it is not the same as endometriosis, which is a separate condition.
CE can develop after pelvic infections, procedures involving the uterus, a retained pregnancy tissue, or changes in the normal bacteria of the reproductive tract. In many women, no clear trigger is ever found.
Can It Cause Symptoms?
Often, it does not. Many women with CE feel completely well. When symptoms occur, they may be mild and easily ignored, such as:
- Spotting between periods
- Heavier or prolonged periods
- Mild pelvic discomfort
- Unusual vaginal discharge
Because symptoms are subtle or absent, CE is sometimes called a “silent” condition, and it is usually found only when a doctor specifically looks for it.
How Might Inflammation Affect Implantation?
For an embryo to implant, the uterine lining needs to be receptive, with the right mix of hormones, blood supply, and immune cells. Researchers believe that chronic inflammation may disturb this balance, changing how the lining responds to hormones and how immune cells behave around the embryo.
Several studies have found that CE is more common in women with repeated implantation failure or recurrent pregnancy loss, and some report better outcomes after treatment. However, much of this evidence comes from observational studies rather than large randomised trials, and reported figures vary widely. For that reason, CE is considered a possible contributing factor, not a proven cause in every case.
Who Should Consider Testing?
Not every IVF patient needs testing. At our IVF Clinic in Noida, your doctor may discuss it if you have:
- Repeated implantation failure, meaning several transfers of good-quality embryos without pregnancy
- Recurrent miscarriage
- Abnormal bleeding or spotting without another explanation
- A history of pelvic infection or uterine procedures
- Suspicious findings on an earlier ultrasound or hysteroscopy
If this is your first IVF cycle and no risk factors exist, routine testing is usually not needed. Your doctor will weigh your history before recommending any investigation.
How Is Chronic Endometritis Diagnosed?
There is no single universal test, and different laboratories use slightly different criteria. Doctors commonly use one or more of the following.
- Hysteroscopy. A thin camera is passed into the uterus so the lining can be seen directly. Features such as redness, swelling, and tiny polyp-like changes may raise suspicion of CE. Hysteroscopy also checks for polyps, adhesions, and other structural problems.
- Endometrial biopsy with special staining. A small sample of lining is taken and examined under the microscope. A stain called CD138 helps identify plasma cells, a type of immune cell whose presence in the lining is the key sign of CE. The number of plasma cells needed for diagnosis is not standardised across laboratories, so results should be interpreted by an experienced pathologist.
- Microbiological tests. Samples may be tested for bacteria to guide treatment, although results do not always identify an organism.
A biopsy is usually done in a specific phase of the cycle, and your doctor will give instructions. It may cause cramping for a short time, similar to period pain.
How Is It Treated?
If CE is confirmed, treatment is usually a course of antibiotics chosen by your doctor, often for about two weeks, depending on the likely bacteria and your medical history. In some cases, a second antibiotic course is needed if inflammation persists.
Some doctors recommend a repeat biopsy after treatment to check that the inflammation has settled before the next embryo transfer. Others adjust plans based on symptoms and the clinical picture, so approaches vary.
An important caution: never take antibiotics on your own because you suspect CE. Unnecessary antibiotics can cause side effects and resistance, and they may hide the underlying problem. Treatment should follow a confirmed diagnosis and a prescription from your doctor.
What Happens After Treatment?
Once the lining is considered healthy, your doctor will plan the next steps for IVF Treatment in Noida. This is often a frozen embryo transfer in a carefully prepared cycle, particularly if you already have frozen embryos. Because evidence on how much treatment improves live birth rates is still being studied, your doctor will give you realistic expectations rather than promises.
Other Causes Worth Checking
CE is only one possible reason for implantation difficulties. A thorough review at our IVF Centre in Noida may also look at:
- Embryo chromosomes and quality
- Uterine shape, polyps, fibroids, or scar tissue
- Fluid-filled or damaged fallopian tubes
- Thin endometrium
- Hormonal and thyroid health
- Sperm and egg factors
- Timing of the transfer
Looking at the full picture avoids focusing on one explanation too early.
