Found yourself searching BCL6 positive forum threads at 2 AM? Increasingly, thanks to accessible testing and treatment pathways, you’re absolutely not alone.
Whether you’re just starting fertility investigations, on your second or third transfer, and/or feeling completely burnt out from the ‘unexplained infertility’ label, we’re here to walk you through what BCL6 positive means – and why it might finally give you some answers.
Together with the brilliant team at ReceptivaDx™ – the only test that can identify one of the leading causes of unexplained infertility in a single sample, uterine lining inflammation – we’re unpacking the science, the stats, and the treatment paths.
We know how frustrating a new rabbit hole can be, and you’ll find clear direction here, from us and ReceptivaDx – practical, research-backed guidance to help you advocate for yourself and ask the right questions.
First, what is BCL6?
Let’s start with the basics: BCL6 is a protein marker linked to inflammation on the uterus, most often caused by endometriosis. Unlike traditional markers or signs of endometriosis – like pelvic pain or heavy periods – BCL6 will pick up inflammation from asymptomatic or silent endometriosis (a very common result for women who have failed IVF).
In fact, BCL6 is found in over 50% of women with unexplained infertility, and 65% of those with two or more failed IVF cycles.

So if you receive a BCL6 positive result on your endometrial biopsy, it means there’s likely underlying inflammation – most often linked to endometriosis – that could be blocking successful embryo implantation.
What does BCL6 positive actually mean?
In fertility terms, a BCL6 positive result means your uterine lining is showing signs of inflammation, which has been scientifically linked to:
- Failed embryo implantation
- Recurrent pregnancy loss
- Progesterone resistance, which reduces the effectiveness of fertility medications and natural conception cycles.
This inflammation doesn’t just exist quietly – it actively disrupts the environment your embryo needs to implant and grow.
BCL6 is identified through the ReceptivaDx™ test, a specialized endometrial biopsy that looks for signs of endometriosis, progesterone resistance and through an add-on marker CD138, the presence of endometritis, too.
So while the result focuses on BCL6, it can actually offer insights into a bigger picture – particularly for those navigating unexplained infertility.
What causes a positive BCL6 result?
In most cases, endometriosis is the culprit, even when you’ve never had the usual symptoms. This is what makes BCL6 such a game-changer – it helps to uncover silent endometriosis that would otherwise go undiagnosed.
Other causes can include:
- Chronic inflammation known as endometritis, in the endometrium
- Hormonal imbalances, especially involving progesterone resistance (progesterone is needed to thicken the endometrium in preparation for pregnancy)
- Structural abnormalities in the uterus, in rarer cases
Ultimately, BCL6 positive results are your body’s way of waving a red flag that something is disrupting your uterine environment – something that might not be visible through ultrasounds or other conventional tests.
Can you have a positive BCL6 result without endometriosis?
This is a great question and one many people ask once their result comes through.
Yes, you can test BCL6-positive without having surgically-confirmed endometriosis.
But even in these cases, it’s believed that the inflammation is still functioning like endometriosis in terms of how it impacts implantation and fertility. It’s why ReceptivaDx™ is such a key tool in fertility diagnostics – it doesn’t wait for visible scarring or symptoms, it detects the issue at a cellular level, in the lining itself.
So whether or not you go on to have a formal diagnosis of endometriosis, the presence of BCL6 is still a major fertility clue.
What are the treatment options for a BCL6 positive result?
OK, so you’ve got a positive result. Now what?
The next step is critical: a customized treatment plan to address the inflammation and improve your odds of a successful embryo transfer.
Here’s what that might look like:
1. Hormone suppression therapy
Usually involving 60 days of medication like Lupron and/or Letrozole. This approach suppresses endometriosis activity by reducing estrogen, the hormone that feeds endometriosis causing the inflammation, giving your uterine lining time to heal.
2. Laparoscopic surgery
If there’s visible or confirmed endometriosis, surgery may be recommended to remove lesions and improve implantation chances.
3. Antibiotics or steroids
In cases where endometritis is also present – a round of antibiotic treatment may be prescribed.
And here’s the good news
Patients who treat their positive BCL6 result have a 60%+ success rate on their next transfer. Compare that to less than 12% success without treatment, and it’s clear this information can be a game-changer. Read up for more on this, and info for your practitioner.
The takeaway: knowledge is power
We know how emotionally draining the fertility journey can be – especially when you feel like you’re doing everything right but still not getting answers. A BCL6 positive result might feel like yet another hurdle, but in reality, it could be your first real clue about what’s going on.
With this information, you can take real, effective steps to treat the underlying cause of failed IVF cycles or repeated miscarriages. And that, for many people, opens the door to a successful pregnancy.

Next steps
For people navigating fertility – often later in life (hi, fellow millennials), often while juggling careers, costs, and information overwhelm – clear direction is everything. Testing positive for BCL6 might sound like bad news, but it’s actually the opposite: it means there’s something you can treat. And in fertility, that’s golden.
If you’re feeling stuck, ask your provider about ReceptivaDx™, and keep pushing for clarity. You’ve got this.
