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
Difficulty getting pregnant is, for some people, the first sign that endometriosis or adenomyosis may be involved—arriving before any other symptom raises suspicion. While the clinical threshold is typically 12 months of trying (or 6 months for those 35 and older), many people seek answers sooner, especially when other risk factors are already on their radar.
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. Learn more about our approach to advanced minimally invasive care at Surgery & Advanced Excision and about surgeon expertise and complex-case management with Dr. Steven Vasilev.
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
Why do endometriosis doctors focus so much on fertility?
Many clinicians focus on fertility because endometriosis can affect it through several pathways—not just “blocked tubes.” Disease can distort pelvic anatomy with adhesions, create an inflammatory environment that interferes with fertilization and implantation, and sometimes impact ovarian reserve (especially when endometriomas are involved). Fertility is also time-sensitive, so teams often raise it early to avoid surprises and to help patients make decisions that still keep future options open.
That said, fertility should never be the only lens. Endometriosis is a whole-body, quality-of-life disease—pain, bowel and bladder symptoms, fatigue, painful sex, and missed work or school are valid reasons to pursue evaluation and treatment whether or not pregnancy is a goal. In our practice, we center the plan on what matters to you—symptom relief, long-term function, and, if relevant, a thoughtful fertility strategy that fits your timeline. If you’re feeling dismissed or “reduced to your uterus,” reach out to schedule a consultation so we can map out an individualized plan that treats you as a whole person.
Can endometriosis be present with normal ultrasound and MRI?
Yes. It’s very possible to have endometriosis even when an ultrasound and MRI are read as “normal,” because imaging is not a simple yes/no detector for all lesion types or locations. Scans are best at spotting certain patterns—like ovarian endometriomas or some deep disease—but superficial implants, small lesions, or disease hidden in less-visible areas can be missed. That’s why a normal scan should never automatically cancel out symptoms like cyclical pelvic pain, painful sex, bowel/bladder symptoms, or infertility.
In our evaluation process, we use imaging as one piece of the puzzle—often more for mapping suspected disease and planning safe surgery than for ruling endometriosis in or out. We put major weight on your full symptom story, flare patterns, and a careful exam, and we also look for conditions that can mimic or coexist with endometriosis (including adenomyosis, pelvic floor dysfunction, vascular causes of pelvic pain, and other drivers of inflammation). If your symptoms persist despite “normal” imaging, reach out to our team—our job is to connect the dots and build a clear, actionable plan toward diagnosis and lasting relief.
Can IVF workup detect endometriosis?
Yes—endometriosis can be suspected during an IVF workup, but it’s often not definitively “found” unless there’s a clear clue. Antral follicle count ultrasound may reveal an ovarian endometrioma, and your history (painful periods, pain with sex, bowel/bladder symptoms, prior cysts) can raise suspicion even when routine imaging looks normal.
What IVF testing typically can’t do is reliably rule endometriosis out. Superficial disease and many forms of deep endometriosis may be missed on standard pelvic ultrasound, and even high-quality imaging needs expert interpretation to identify subtler patterns or related conditions like adenomyosis.
If endometriosis is a concern during fertility planning, our team focuses on a thorough, story-driven evaluation plus targeted exam and expertly interpreted ultrasound/MRI when appropriate—so you’re not left guessing between “unexplained infertility” and a potentially treatable root cause. If you’re in the middle of IVF decisions, reach out to schedule a consultation so we can help you clarify what may be present and how it could impact next steps.
Can an HSG detect endometriosis?
An HSG (hysterosalpingogram) is designed to evaluate the uterine cavity and whether the fallopian tubes are open, so it does not reliably “detect” endometriosis. Most endometriosis lesions live on the outside surfaces of pelvic organs or deeper within tissues—areas an HSG can’t visualize.
That said, an HSG can sometimes hint at problems that can coexist with endometriosis or be related to it, like tubal blockage, scarring, or distorted tubal anatomy—findings that matter, especially when fertility is part of the concern. In our evaluation process, we look at your full symptom pattern and history and then use targeted tools like expertly interpreted ultrasound or MRI when appropriate, with surgery and tissue confirmation reserved for situations where it will truly change management.
If you’ve had an HSG and still feel you don’t have clear answers, we can help you connect the dots—endometriosis is often missed when testing is limited to what’s easiest to measure. Reach out to schedule a consultation so our team can review your symptoms and prior imaging and map out the most direct path to an accurate diagnosis and durable relief.
What tests check infertility when endometriosis is suspected?
When infertility and suspected endometriosis overlap, we usually evaluate two things in parallel: whether there’s an underlying fertility factor (ovulation, sperm, tubal/uterine issues) and whether endometriosis or adenomyosis is likely contributing through inflammation, adhesions, or anatomic distortion. The workup often starts with a detailed history of cycle patterns, pain and bowel/bladder symptoms, prior pregnancies or losses, and any past surgeries—because the symptom pattern can help us target the right testing instead of repeating “normal” basics.
Testing commonly includes pelvic imaging—typically a high-quality transvaginal ultrasound and, when indicated, expertly interpreted MRI—to look for endometriomas, deep disease features, adenomyosis, and other pelvic conditions that can impact implantation or egg pickup. A fertility evaluation may also include ovarian reserve and hormone labs, confirmation of ovulation timing, and assessment of the uterine cavity and fallopian tubes (for example with contrast-based imaging) plus a semen analysis for your partner. In selected patients, we also look for coexisting issues that can complicate fertility or mimic endo symptoms—such as thyroid dysfunction, PCOS patterns, autoimmune overlap, or other whole-body drivers that can amplify inflammation.
It’s important to know that imaging and labs can strongly raise or lower suspicion, but endometriosis is ultimately confirmed by tissue diagnosis when surgery is performed, and biopsy results depend on sampling and surgical expertise. If you share what testing you’ve already had and your main symptoms, our team can review your records, identify what’s missing (if anything), and map out the most efficient next steps—whether that’s further evaluation, fertility planning, or considering excision surgery as part of a fertility-focused strategy.
Is laparoscopy necessary for infertility from endometriosis?
Not always—but laparoscopy (surgery) is often the step that brings clarity when endometriosis is a suspected driver of infertility. Endometriosis can reduce fertility through inflammation, endometriomas, scarring/adhesions that distort the ovaries and tubes, and changes that interfere with egg pickup, embryo transport, or implantation. Imaging and clinical evaluation can strongly suggest disease in some patients, but endometriosis still can’t be definitively diagnosed without surgically removing tissue for confirmation.
When infertility is the main concern, the real question is usually whether surgery is likely to improve your specific barriers to conception—such as a suspected endometrioma, tubal damage, or deep disease affecting pelvic anatomy. In those cases, our team typically focuses on complete excision (rather than burning lesions), because leaving disease behind can mean persistent inflammation and ongoing fertility challenges. If you’re trying to decide whether surgery belongs in your fertility plan, we can walk through your full history, imaging, and goals and map out a strategy that fits—whether that means moving toward excision, coordinating with fertility treatment, or first ruling out other common contributors that can look like (or coexist with) endometriosis.
Can you have endometriosis without pelvic pain?
Yes—endometriosis can be present even if you don’t have classic pelvic pain. Symptom severity doesn’t reliably match the amount, location, or “stage” of disease, and some people have minimal or no pain despite significant findings.
When pelvic pain isn’t the main feature, endometriosis may show up in other ways, such as infertility, heavy or abnormal bleeding patterns, pain with sex, bowel or bladder symptoms (especially if they fluctuate with your cycle), or persistent bloating and GI disruption that gets mislabeled as “just IBS.” Because endometriosis can involve different organs and can coexist with look-alike conditions, our evaluation focuses on your full symptom pattern, exam findings, and high-quality imaging when appropriate.
If you suspect endometriosis despite little or no pelvic pain, we can help you sort out whether endometriosis is likely, what else could be contributing, and whether a surgical diagnosis and strategic excision makes sense for your goals (pain relief, fertility, or both). You can explore our approach and reach out to schedule a consultation with our team when you’re ready.
Egg freezing vs embryo freezing with endometriosis: which is better?
If you have endometriosis, “better” usually depends on what decision you can make right now: do you have (or want to use) a specific sperm source, and are you trying to preserve fertility as a solo option or as a plan with a partner. Embryo freezing often gives the clearest picture of what you’ve preserved because eggs have already been fertilized and developed, while egg freezing preserves reproductive flexibility if your plans, relationship status, or sperm choice could change.
Endometriosis can affect fertility through more than one pathway—ovarian factors (including endometriomas and ovarian reserve), pelvic anatomy/adhesions, and implantation biology—so freezing is often part of a bigger strategy rather than the whole answer. If your main concern is protecting future options before possible surgery or as time passes, egg freezing may fit that goal; if your priority is maximizing a known plan with known sperm, embryo freezing may be the more direct path.
We help patients map these choices to their actual situation—your age and ovarian reserve markers, whether endometriomas are present, prior surgeries, pain/inflammation patterns, and whether there may be additional fertility factors beyond endometriosis. If you’d like, reach out to our team for a coordinated plan that fits both symptom management and fertility preservation, so the timing of treatment and the next steps make sense together.
