Chronic Endometritis Before IVF: When It Matters and How It Is Confirmed
Key Takeaways
Chronic endometritis is a low-grade inflammation of the uterine lining that may interfere with implantation, recurrent miscarriage, or repeated IVF failure. It is often silent, so diagnosis usually depends on biopsy rather than symptoms alone.
Chronic Endometritis and IVF
Chronic endometritis is a persistent, low-grade inflammation of the uterine lining. It is different from acute pelvic infection because symptoms may be mild or absent, yet the endometrium may still be less favorable for implantation.
This is why the condition is often discussed in patients with repeated embryo transfer failure, recurrent miscarriage, or unexplained infertility.
Why It Matters in IVF
The concern is not simply that inflammation exists, but that it may change the uterine environment in ways that interfere with implantation or early placental development.
Not every failed IVF cycle is caused by chronic endometritis, and not every patient should be screened automatically. But when the clinical history raises concern, it can be a relevant diagnosis to evaluate.
Why It Is Easy to Miss
Many patients with chronic endometritis have no clear symptoms. Others may have:
- irregular bleeding
- spotting
- pelvic discomfort
- unusual discharge
These signs are nonspecific, which is why symptoms alone are not enough to make or exclude the diagnosis.
How It Is Diagnosed
Diagnosis is usually based on endometrial sampling rather than ultrasound alone. Common tools include:
- hysteroscopy, which may show indirect signs
- endometrial biopsy
- CD138 staining, used to identify plasma cells in the sample
This biopsy-based approach is generally considered more reliable than guessing from symptoms or imaging.
When It Is Usually Investigated
Clinicians are more likely to consider evaluation when there is:
- recurrent implantation failure
- recurrent pregnancy loss
- unexplained infertility
- suspicious hysteroscopic findings
Routine testing in every IVF patient is more controversial, and the value of screening depends on the clinical context.
Treatment
When chronic endometritis is confirmed, treatment often includes antibiotics chosen according to local practice, culture information when available, and clinical history. Some patients undergo repeat evaluation afterward to check whether the inflammatory finding has cleared.
The key point is that treatment should follow a real diagnosis, not just a vague suspicion.

FAQ
Can chronic endometritis be found on ultrasound alone?
Usually not reliably. Ultrasound may raise suspicion in some cases, but diagnosis generally depends on endometrial sampling, often with biopsy and CD138 staining.
Should every IVF patient be tested for chronic endometritis?
No. Routine screening in every patient remains controversial. Evaluation is usually more relevant after repeated implantation failure, recurrent pregnancy loss, unexplained infertility, or suspicious cavity findings.
If chronic endometritis is treated, does IVF success always improve?
Not automatically. Treatment may help when the diagnosis is real and clinically relevant, but it does not explain every failed transfer and should not be sold as a universal fix.
Chronic endometritis may be an important piece of the puzzle in selected IVF patients, especially after repeated failed transfers or recurrent miscarriage. Its main challenge is that it is often silent, so biopsy-based confirmation is more useful than symptom-based assumptions.
