Adenomyosis and Fertility: What the Research Shows

If you’ve recently heard the word adenomyosis at an ultrasound or MRI appointment, you might be wondering what it means for your plans to grow your family. Adenomyosis is less well known than endometriosis, and the research on adenomyosis and fertility is still evolving. Here’s a clear overview of what the condition is, what the studies suggest so far, and what treatment conversations often look like.

What is adenomyosis?

Adenomyosis happens when tissue similar to the uterine lining (the endometrium) grows into the muscular wall of the uterus (the myometrium). This can make the uterine wall thicker and the uterus larger. It can be diffuse, spread throughout the wall, or focal, concentrated in one area, sometimes called an adenomyoma.

Adenomyosis often occurs alongside endometriosis or fibroids, which can make the picture more complicated. Our guides on endometriosis and fertility and uterine fibroids and fertility explain how those conditions differ.

Common symptoms

Some people with adenomyosis have no symptoms at all. Others notice:

• Heavy or prolonged menstrual bleeding
• Painful periods that may worsen over time
• Pelvic pain or pressure
• Pain during sex
• A tender or enlarged uterus on exam

Many people find comfort from a heating pad on painful days. Talk with your doctor about pain relief options that fit your treatment plan, since some medications aren’t recommended during certain cycle phases or treatments.

How adenomyosis is diagnosed

In the past, adenomyosis was often only confirmed after a hysterectomy. Today, imaging has improved a lot. Doctors commonly use a transvaginal ultrasound or an MRI to look for features suggestive of adenomyosis. Imaging can’t always give a definitive answer, and findings may be described as “suggestive of” or “consistent with” adenomyosis.

What the research shows about adenomyosis and fertility

This is where honest uncertainty matters. Research on adenomyosis and fertility has been limited by differences in how it’s diagnosed and measured, and many studies are small. That said, several themes come up repeatedly:

• Some studies have associated adenomyosis with lower implantation rates in IVF
• Some research suggests a higher risk of miscarriage in people with adenomyosis
• The severity and type, diffuse versus focal, may matter
• Possible explanations include changes in how the uterine muscle contracts, inflammation, and changes in the uterine lining

It’s important to remember that many people with adenomyosis do conceive and have healthy pregnancies, both with and without treatment. A diagnosis is a reason for thoughtful planning, not a reason to lose hope. For more on the inflammation piece, see how inflammation affects implantation.

Treatment options when you’re trying to conceive

There’s no single standard approach, and recommendations depend on your symptoms, age, other diagnoses, and fertility history. Options your doctor may discuss include:

Hormonal suppression before a frozen transfer

Some clinics use a period of GnRH agonist or other suppressive medication before a frozen embryo transfer to try to quiet adenomyosis. Some research suggests this may help in certain cases, though the evidence isn’t conclusive and practices vary between clinics.

Frozen rather than fresh transfer

Because stimulation can raise estrogen levels, some doctors prefer a freeze-all approach followed by a prepared frozen transfer for patients with adenomyosis.

Surgery

For focal adenomyosis, surgery to remove the affected area is sometimes considered. It’s a specialized procedure with risks, including effects on the uterine wall in a future pregnancy, so it’s usually reserved for specific situations and done by experienced surgeons.

Managing symptoms

Hormonal treatments like birth control or hormonal IUDs can ease symptoms, but they prevent pregnancy, so they’re often used between attempts or after family building.

Caring for yourself along the way

Living with a condition that causes pain and uncertainty can be exhausting, especially on top of trying to conceive. Tracking your symptoms, bleeding, and pain levels over a few cycles can give your doctor a clearer picture and help you notice patterns. A simple symptom tracker journal works well for this. Some people also find it helpful to read about the experiences of others with pelvic pain conditions, such as in books about endometriosis and adenomyosis. And don’t underestimate rest, gentle movement, and asking for help on heavy days.

Questions to ask your doctor

• Is my adenomyosis diffuse or focal, and how extensive is it?
• Do I also have endometriosis or fibroids?
• Would you recommend suppression before a transfer, and why?
• How might adenomyosis affect my pregnancy care?
• Should I consider a second opinion from a specialist?

Bringing a written list helps. Our guide to advocating for yourself at the fertility clinic has more tips.

Frequently asked questions

Can you get pregnant naturally with adenomyosis?

Yes, many people do. Adenomyosis may make conception or carrying a pregnancy harder for some, but it doesn’t rule it out. Your doctor can help you decide how long to try before seeking treatment.

Does adenomyosis go away?

It typically improves after menopause, when estrogen levels fall. Before that, treatments can help manage symptoms, but there isn’t a cure short of hysterectomy.

Is adenomyosis the same as endometriosis?

No. They are related but different. Endometriosis involves endometrial-like tissue outside the uterus, while adenomyosis involves it within the uterine muscle. Many people have both.

The bottom line

Adenomyosis can affect fertility, but the research is still developing, and many people with this diagnosis go on to build their families. Work with a reproductive endocrinologist who is familiar with the condition, ask about tailored transfer strategies, and get support for the pain and stress along the way. Share this with someone who has just received the same diagnosis.

PUTTING THIS IN CONTEXT

One result is a starting point—not the whole story.

Fertility decisions rarely come down to a single test, scan, symptom, or statistic. Your history, timing, goals, partner factors, and the way results change over time can all affect what is most useful to discuss next.

Use this guide to get oriented, write down questions, and have a more informed conversation with a qualified clinician who knows your full situation.

Questions you may want to bring to your appointment

• How does this information fit with my personal history and current goals?
• Would repeating or pairing this test with another result change what we learn?
• What options are reasonable now, and what can wait?
