Adenomyosis and Fertility: How It Affects IVF and What Can Help

What Is Adenomyosis?

Adenomyosis is a condition in which endometrial tissue, the type of tissue that normally lines the inside of the uterus, grows into the muscular wall of the uterus itself. Each month this misplaced tissue responds to hormonal signals just like the normal uterine lining does, thickening and bleeding within the muscle. Over time this can cause the uterus to become enlarged, thickened, and less flexible than it should be. Adenomyosis is fairly common, particularly in women in their late thirties and forties, though it can also affect younger women, including some who have not yet had children.

Common Symptoms

Some women with adenomyosis have no noticeable symptoms at all, and the condition is only discovered during a scan for another reason. When symptoms do occur, they often include heavy or prolonged menstrual bleeding, painful periods that may worsen over time, pelvic pain or pressure outside of menstruation, and a uterus that feels enlarged or tender. Pain during intercourse is also reported by some women. Because these symptoms overlap with several other gynecological conditions, adenomyosis is sometimes missed or diagnosed later than it could be.

Adenomyosis, Endometriosis, and Fibroids: What Is the Difference

These three conditions are often confused because they can share symptoms such as pelvic pain and heavy bleeding, and it is possible to have more than one at the same time. Endometriosis involves endometrial-like tissue growing outside the uterus, often on the ovaries, fallopian tubes, or pelvic lining. Fibroids are benign muscle growths that develop within or on the uterine wall but are made of different tissue than the uterine lining. Adenomyosis is distinct from both because the displaced tissue is endometrial in origin but located within the uterine muscle itself. Distinguishing between these conditions matters because the approach to fertility treatment can differ depending on which one, or which combination, is present.

How Adenomyosis May Affect Fertility and IVF

Implantation Challenges

An enlarged, structurally altered uterus may not provide the same receptive environment for an embryo as a healthy uterine lining. Some studies suggest that adenomyosis is associated with lower implantation rates and a reduced likelihood of pregnancy following IVF, though findings vary and the relationship is not fully understood. Researchers believe the muscular changes, altered blood flow, and inflammatory changes within the uterus may all play a role.

Increased Miscarriage Risk

There is evidence pointing to a higher risk of early pregnancy loss in women with adenomyosis, likely related to the same structural and inflammatory factors that can affect implantation. It is important to say clearly that having adenomyosis does not mean a pregnancy will not succeed, but it is a factor that a fertility specialist will want to take into account when planning treatment and counseling on realistic expectations.

How Adenomyosis Is Diagnosed

Diagnosis usually starts with a detailed history of symptoms combined with a pelvic ultrasound, which can often show signs such as an enlarged or asymmetrical uterus, thickened muscle walls, or small cystic areas within the muscle. When ultrasound findings are unclear, magnetic resonance imaging, or MRI, can provide a more detailed picture of the uterine structure and help distinguish adenomyosis from fibroids or other conditions. In the past, adenomyosis could only be confirmed after hysterectomy, but modern imaging has made it possible to identify the condition while preserving fertility options.

Approaches That May Help When Trying to Conceive

Hormonal Suppression Before Embryo Transfer

One approach some fertility specialists consider is a period of hormonal suppression, using medications that temporarily reduce estrogen and quiet the activity within the uterine muscle, before proceeding with a frozen embryo transfer. The idea is to reduce inflammation and allow the uterine environment to settle before an embryo is introduced. This approach is used selectively and is tailored to the individual, based on the severity of adenomyosis and the person’s overall fertility history.

Tailored IVF Protocols

Because adenomyosis varies so much in severity and location within the uterus, a one-size-fits-all approach rarely makes sense. A fertility specialist may adjust stimulation protocols, consider extended monitoring of the uterine lining, or recommend a frozen embryo transfer cycle rather than a fresh transfer, giving more control over the timing and hormonal environment. Some clinicians also discuss the role of anti-inflammatory or hormonal medications used prior to transfer, though the evidence base for many of these interventions is still developing.

An Honest Note on the Evidence

It is worth being transparent that research on adenomyosis and fertility treatment is still evolving. Study sizes are often small, definitions of adenomyosis vary between researchers, and results are not always consistent. This does not mean nothing can be done, but it does mean that treatment decisions should be individualized and made in close conversation with a specialist who can review your specific scans, history, and goals rather than following a generic protocol.

Living With Adenomyosis While Trying to Conceive

Beyond the medical steps, adenomyosis can be emotionally taxing, particularly when it is diagnosed during a fertility journey that already feels uncertain. Chronic pelvic pain and heavy periods can affect daily life and wellbeing well before pregnancy is even part of the conversation. Seeking support, whether through a fertility counselor, a support group, or simply an open conversation with your care team, is a reasonable and valuable part of managing this condition alongside any fertility treatment.

Frequently Asked Questions

Can I still get pregnant naturally with adenomyosis

Many women with adenomyosis do conceive, either naturally or with fertility treatment. The condition can make conception more difficult for some, but it does not rule out pregnancy, and outcomes vary widely depending on severity, age, and other individual factors.

Does adenomyosis always require treatment before IVF

Not always. Mild adenomyosis with no significant symptoms may not require specific pretreatment, while more extensive disease may prompt a specialist to recommend a period of hormonal management before attempting embryo transfer. This decision depends on individual imaging findings and history.

Is adenomyosis the same as having fibroids

No. Fibroids are separate benign growths within the uterine wall, while adenomyosis involves endometrial tissue embedded directly within the uterine muscle. The two conditions can occur together, and imaging is usually needed to tell them apart.

Will adenomyosis affect egg or embryo quality

Adenomyosis primarily affects the uterus itself rather than the ovaries, so it is not generally understood to directly affect egg quality. Its main impact is thought to relate to the uterine environment and implantation rather than the eggs or embryos.

If you have been diagnosed with adenomyosis, or suspect you may have symptoms of it, and are thinking about your fertility options, you do not have to work through the questions alone. The team at GynoLife IVF Center in Cyprus can review your history and imaging, walk you through what a tailored plan might look like, and answer your questions honestly, including where the evidence is still developing. Reaching out for a consultation is a good first step toward understanding your own situation more clearly.
