Infertility
Infertility can be the first noticeable sign of endometriosis or adenomyosis—especially when you feel otherwise “fine,” yet pregnancy isn’t happening. Both conditions can affect the pelvis in ways that disrupt ovulation, fertilization, implantation, and early pregnancy.
Overview
Infertility means difficulty getting pregnant after regular, unprotected sex. Clinically, it’s often defined as 12 months of trying if you’re under 35 (or 6 months if you’re 35 or older), but many people seek help sooner when symptoms or known risk factors are present. For some, infertility is the first and only clue that something like endometriosis or adenomyosis may be affecting reproductive function.
With endometriosis, endometrial-like tissue grows outside the uterus—commonly in the pelvis on the ovaries, fallopian tubes, pelvic sidewalls, bladder, bowel, and ligaments. Even when lesions are “small,” the disease can create inflammation, scarring (adhesions), and distorted pelvic anatomy that interferes with egg release, egg pickup by the tube, fertilization, or embryo transport. Endometriosis can also affect egg quality and ovarian reserve, especially when ovarian cysts called endometriomas are present.
With adenomyosis, endometrial tissue grows into the muscular wall of the uterus. This can change how the uterus contracts, increase local inflammation, and alter the uterine environment in ways that may reduce implantation and increase the risk of early pregnancy loss for some patients. Adenomyosis also frequently co-occurs with endometriosis, which can compound fertility challenges.
Infertility has many possible causes—such as ovulation disorders, thyroid disease, male factor infertility, fibroids, tubal blockage from prior infection, or age-related decline—so difficulty conceiving doesn’t automatically mean endometriosis or adenomyosis. What makes endometriosis/adenomyosis distinctive is the combination of pelvic disease biology (inflammation, scarring, immune changes) with symptoms that may include painful periods, pelvic pain, bowel/bladder symptoms, or pain with sex—though symptoms can be minimal or absent.
Beyond the medical definitions, infertility can affect every part of life: relationships, intimacy, mental health, finances, and your sense of control over your body. If you suspect endometriosis or adenomyosis, a specialist-focused evaluation (not “wait and see”) can clarify what’s driving the problem and what options best fit your goals. You can learn more about how we approach this at Evaluation & Diagnosis.
What It Feels Like
Infertility often doesn’t “feel” like a physical symptom at first—it can feel like time passing: month after month of negative pregnancy tests, hope followed by disappointment, and the sense that your body isn’t doing what it’s supposed to. Many patients describe it as a quiet but persistent stressor that affects mood, sleep, concentration, and relationships.
When infertility is linked to endometriosis or adenomyosis, it may be accompanied by pelvic symptoms such as painful periods, pelvic pain, deep pain during intercourse, bowel or bladder discomfort, or fatigue—but not always. Some people are surprised to learn they have endometriosis because their periods are “normal enough,” yet conception remains difficult.
Experiences can vary widely. One person may have severe pelvic pain and still conceive quickly, while another with minimal pain may struggle for years. Some notice the difficulty becomes more apparent with age, after stopping birth control, after a miscarriage, or after surgery for ovarian cysts.
For others, the cycle itself becomes a monthly reminder: worsening pelvic pain around ovulation or the period, spotting, or heavy bleeding can intensify the emotional impact. It’s valid to feel grief, anger, numbness, or isolation—especially if you’ve been told your tests are “fine” without deeper investigation.
How Common Is It?
Endometriosis affects approximately 10% of women of reproductive age, and infertility is one of its most well-recognized complications. Estimates vary by study and population, but endometriosis is found in a substantial portion of people evaluated for infertility—often cited around 25–50% in infertility populations. Importantly, infertility may be the first clue because endometriosis can be present for years before diagnosis (often 7–10 years).
Adenomyosis has historically been underdiagnosed, especially in younger patients, but improved imaging has shown it can affect people during reproductive years and may be associated with reduced fertility and lower implantation rates—particularly in IVF settings. Adenomyosis also frequently overlaps with endometriosis, which can make it hard to separate which condition is contributing most.
Infertility risk does not always correlate neatly with visible disease severity. Some patients with minimal disease have significant fertility challenges (likely driven by inflammation/immune effects), while others with advanced disease conceive. Location matters: ovarian endometriomas, deep disease around the tubes/ovaries, and pelvic adhesions are more likely to interfere with conception mechanics.
Causes & Contributing Factors
In endometriosis, infertility can result from multiple overlapping mechanisms. Chronic pelvic inflammation may impair egg quality, sperm function, and fertilization, and it can also disrupt the delicate environment needed for embryo development. Adhesions can “tether” ovaries and tubes, altering normal anatomy so the tube can’t easily pick up the egg after ovulation.
Endometriosis can also affect the ovaries directly. Endometriomas and prior ovarian surgery may reduce ovarian reserve in some patients, and inflammation around the ovary may affect follicle development. Deep infiltrating disease can involve structures near the uterus and tubes, contributing to pain and potentially altering function.
In adenomyosis, the uterine muscle and lining environment may be less favorable for implantation. Proposed contributors include increased local inflammation, altered uterine peristalsis (contractile patterns that can affect sperm/embryo transport), and changes in the junctional zone where implantation-related signaling occurs. Some patients also experience heavy bleeding and anemia, which can add fatigue and stress during fertility attempts.
Both conditions can also contribute to pelvic nerve sensitization and stress physiology, which doesn’t “cause” infertility in a simple way but can worsen pain, reduce sexual comfort and timing, and increase overall strain. Coexisting conditions—fibroids, PCOS, thyroid disorders, male factor infertility—can further affect outcomes, which is why a comprehensive workup matters (see Related Conditions).
Treatment Options
Treatment depends on your age, timeline, symptoms, prior history, and whether the goal is spontaneous conception, fertility preservation, or assisted reproduction. A thorough evaluation often includes ovulation assessment, semen analysis, imaging of uterus/ovaries, and assessment of tubal patency—alongside a targeted endometriosis/adenomyosis evaluation (learn what to expect at Evaluation & Diagnosis).
Medical therapy can be used strategically, especially when adenomyosis or endometriosis inflammation is suspected. Options may include hormonal suppression (such as progestins or other therapies) to reduce inflammatory activity; however, suppressive hormones generally prevent pregnancy while you’re taking them, so timing and sequencing matter. For symptom relief alongside fertility planning, evidence-based options may include targeted pain strategies (see Pain Management) and selected hormonal approaches (see Hormonal Therapy).
Surgery can be a key option for appropriate candidates—especially when endometriosis is suspected to be distorting pelvic anatomy, causing endometriomas, or contributing to significant pain. In expert hands, excision surgery (removal of disease at the root) is considered the gold standard and may improve pain and, in some cases, fertility outcomes.

For adenomyosis-related fertility issues, treatment may include hormone-based strategies to calm disease activity before trying to conceive, optimizing iron stores if bleeding is heavy, and coordinating care with reproductive endocrinology when indicated. Some patients pursue IVF/ART sooner based on age, ovarian reserve, or duration of infertility—especially if tubes are affected or time is critical.
Supportive care matters, too. Pelvic floor physical therapy can help if pain with intercourse is limiting timing, and integrative approaches (sleep, anti-inflammatory nutrition, stress regulation, targeted supplements when appropriate) can support overall health while you pursue definitive treatment; see Integrative Medicine & Lifestyle Care.

When to Seek Help
Seek urgent care right away if you have severe one-sided pelvic pain, fainting, shoulder pain with dizziness, heavy bleeding soaking pads hourly, fever, or suspected pregnancy with pain/bleeding—these can signal emergencies such as ectopic pregnancy or ovarian torsion.
Schedule a specialist visit if you’re under 35 and have been trying for 12 months, if you’re 35+ and trying for 6 months, or sooner if you have symptoms suggestive of endometriosis/adenomyosis (painful periods, pelvic pain, pain with sex, heavy bleeding) or a history of endometriomas, pelvic surgery, or miscarriages. Early intervention matters because endometriosis often takes years to diagnose, and fertility planning is time-sensitive.
When you meet with a clinician, bring a concise timeline: how long you’ve been trying, cycle length/ovulation tracking, pregnancy history, pain and bleeding patterns, prior imaging/surgeries, and any family history. If you’re not getting clear answers—or you’re told it’s “normal” without a plan—it’s reasonable to advocate for specialty evaluation. If you’re ready for expert guidance, you can schedule a consultation.
Frequently Asked Questions
Can infertility be the only sign of endometriosis?
Yes. Some people have endometriosis with minimal or no pain, and infertility becomes the first clue. Endometriosis can impact fertility through inflammation, adhesions, and ovarian effects even when symptoms are subtle. If you’ve been trying without success, it’s reasonable to ask specifically about endometriosis evaluation rather than assuming everything is “unexplained.” You can start by reviewing our approach to endometriosis and Evaluation & Diagnosis.
Does adenomyosis affect implantation and IVF success?
Adenomyosis may affect implantation for some patients by changing the uterine muscle and local inflammatory environment. In IVF settings, some studies associate adenomyosis with lower implantation or higher miscarriage risk, though outcomes vary widely by disease pattern and treatment strategy. The good news is there are management approaches—often involving careful sequencing of medical therapy and fertility treatment—that may improve the uterine environment. Learn more on our adenomyosis page.
If my ultrasound is normal, does that rule out endometriosis or adenomyosis?
No. A normal ultrasound does not rule out endometriosis, especially superficial disease or lesions in certain locations. Ultrasound can sometimes identify endometriomas or deep infiltrating endometriosis, and it can also suggest adenomyosis—but imaging has limits. Many patients still require specialist assessment and, in some cases, surgery for definitive diagnosis of endometriosis. See how we evaluate these conditions at Evaluation & Diagnosis.
Will excision surgery cure infertility?
Excision surgery can improve fertility in some situations—particularly when endometriosis is distorting pelvic anatomy or causing endometriomas or adhesions. However, it’s not a guaranteed “cure,” and the best next step depends on age, ovarian reserve, tubal status, symptoms, and how long you’ve been trying. A fertility-focused plan often considers whether to try naturally after surgery, pursue IUI/IVF, or preserve eggs/embryos. Learn more about expert surgical care at Surgery & Advanced Excision and Dr. Steven Vasilev.
What should I ask my doctor if I suspect endometriosis-related infertility?
Ask what the plan is to evaluate endometriosis/adenomyosis specifically (not just “unexplained infertility”), whether your imaging is optimized, and whether tubal patency and ovarian reserve have been assessed. Ask about the risks/benefits of medical suppression versus moving to fertility treatment, and when surgical consultation is appropriate. If pain is present, ask about treating pain without delaying fertility goals (see Pain Management). If you want a comprehensive, endometriosis-informed plan, you can contact us.
