Yes, silent endometritis can genuinely be the reason an embryo won’t implant. Chronic endometritis is a persistent, low grade inflammation of the uterine lining, usually caused by a bacterial infection that never clears on its own. What makes it “silent” is exactly the problem: there’s rarely pain, unusual bleeding, or discharge severe enough to send someone to a doctor, so it sails straight through a standard fertility workup undetected. The uterus can look completely normal on a routine scan while the lining underneath is quietly inflamed and hostile to implantation.
According to Dr. Nisarg Patel, IVF specialist,says “ this shows up most often in couples who’ve already been through one or more failed transfers with good quality embryos and no obvious explanation. In his experience, once other causes are ruled out, checking the endometrium itself for chronic inflammation is one of the more useful next steps, not a last resort”.
Had good embryos and still no positive result?
How common is this, and why does it get missed?
- Found in roughly a third to two thirds of women with repeated implantation failure, with one study reporting it in over half of women tested after multiple failed embryo transfers
- Rarely causes fever, pain, or obvious discharge like acute endometritis does, so there’s usually nothing that sends a woman to a doctor
- A normal looking ultrasound or pelvic exam won’t catch it, since the inflammation sits at a tissue level those tools can’t see
- Usually caused by common bacteria such as E. coli, Enterococcus, Streptococcus, Mycoplasma, Ureaplasma, or occasionally Chlamydia, none of which need an unusual exposure or risk factor
How is it actually diagnosed and treated?
- Diagnosed through hysteroscopy plus endometrial biopsy, looking for lining swelling, patchy redness, or micropolyps
- Confirmed on biopsy by CD138 staining, which flags the plasma cells that mark chronic inflammation
- Treated with a course of antibiotics, usually doxycycline, sometimes with a second antibiotic and a repeat biopsy if the first course doesn’t clear it
- Cure rates run around 70 to 90 percent, and resolving it has been linked to better implantation rates, so it’s worth testing for before another transfer rather than after another failed one
Why Choose Dr. Nisarg Patel?
Dr. Nisarg Patel is an MBBS and MS in Obstetrics and Gynaecology, with Fellowships in Infertility, IVF, and Obstetric Ultrasound, plus a Diploma in Advanced Gynaec Endoscopy. Over 10 years of clinical work and more than 8,000 IVF cycles handled, including couples referred in after multiple failed transfers where chronic endometritis turned out to be the missing piece.Repeated implantation failure gets a proper endometrial workup here, not just another transfer on the same protocol.

FAQs
Can chronic endometritis cause IVF failure even with a good embryo?
Yes. Chronic inflammation in the uterine lining can prevent even a genetically normal, good quality embryo from implanting successfully.
What symptoms does silent endometritis actually cause?
Often none, or symptoms mild enough to overlook, such as slight spotting or a subtle change in period pattern. That’s why it needs to be actively tested for rather than diagnosed from symptoms
How is chronic endometritis diagnosed?
Through hysteroscopy and an endometrial biopsy checked for CD138 positive plasma cells, which is the standard confirmatory test.
Is chronic endometritis treatable before another embryo transfer?
Yes, it’s usually treated with a course of antibiotics, with a repeat biopsy sometimes done to confirm the infection has cleared before proceeding.
