How Is Endometriosis Different From Fibroids? Symptoms, Fertility & Treatment
UPDATED ON 18 FEB. 2026
As a fertility specialist in Mumbai, I often meet women confused about whether their symptoms are due to fibroids, endometriosis, or sometimes both.
While these conditions frequently cause pain, heavy bleeding, and sometimes even impact fertility, it's important to know that they are fundamentally different disorders—each requiring its own approach to diagnosis and management.
Fibroids are benign (non-cancerous) muscular growths in or on the uterus, whereas endometriosis occurs when tissue similar to the uterine lining grows outside the uterus.
If you are struggling with these symptoms, you are not alone. I am Dr. Jay Mehta, and my goal with this guide is to help you clearly identify the differences and similarities, as well as the best treatment strategies, so you can make confident decisions for your health.
Are Fibroids and Endometriosis the Same?
Absolutely not—fibroids and endometriosis are not the same
Though both are benign gynecological conditions that sometimes present with overlapping symptoms, their origins, effects on the uterus and fertility, and best management paths are very different.
Because the clinical picture can sometimes be confusing, an accurate diagnosis with a qualified specialist is essential for your care.

Similarities Between Fibroids and Endometriosis
It's easy to see why so many women confuse these conditions, as they share important commonalities:
- Both most often affect women in their reproductive years (ages 20-45).
- Symptoms can include pelvic pain, heavy or irregular menstrual periods, and difficulty conceiving.
- Both are strongly influenced by oestrogen and related hormones.
- It is possible (and not uncommon) for a patient to have both conditions at the same time.
- Neither condition is cancerous in the vast majority of cases.
- Accurate diagnosis and treatment are best achieved at specialist centres like Shree IVF Clinic in Mumbai, using modern, minimally invasive techniques.
If you are struggling with pelvic pain, abnormal bleeding, or infertility, take the first step towards clarity and relief.

Key Differences Between Fibroids and Endometriosis
While fibroids and endometriosis share some similarities, their key differences are important for both diagnosis and management. Here’s a side-by-side look to help you understand how they differ:
| Aspect | Uterine Fibroids | Endometriosis |
|---|---|---|
| Origin | Benign tumors of the smooth muscle of the uterus (myometrium), also called leiomyoma or myoma of the uterus | Growth of tissue similar to the uterine lining (endometrium) outside the uterus |
| Location | Within or attached to the uterus—can be inside the cavity (submucosal), in the muscle wall (intramural), or on the outer surface (subserosal/pedunculated) | Found outside the uterus—on ovaries, fallopian tubes, pelvic ligaments, bowel, bladder, and rarely distant organs |
| Typical Symptoms | Heavy/prolonged periods, pelvic pressure or bloating, urinary frequency, constipation, fertility issues, and pain usually linked to size/location | Severe cyclical pain before/during periods, pain during intercourse, painful urination/bowel movements (especially during periods), infertility, chronic pelvic pain |
| Menstrual Changes | Heavy menstrual bleeding (menorrhagia), passage of clots, sometimes anemia | Can cause both heavy or irregular periods, often with severe premenstrual and menstrual pain |
| Relation to Fertility | May block tubes, change uterine shape, or interfere with implantation; usually treated surgically for fertility | An inflammatory environment damages eggs, tubes, and pelvic anatomy; adhesions may distort organs and block tubes; surgical excision is often needed for fertility |
| Diagnosis | Usually detected by transvaginal pelvic ultrasound or MRI; can be mapped by specialists | Laparoscopy is the gold standard; can be suspected via history, exam, and sometimes MRI or specialized ultrasound (for endometriomas or deep lesions) |
| Treatment Approach | Medication can temporarily reduce size/symptoms; definitive treatment is surgical removal (myomectomy, hysteroscopic/laparoscopic/robotic); hysterectomy is a last resort | Medical therapy focuses on pain and suppressing periods (hormonal medications); surgical excision (laparoscopy) is the gold standard for symptom control and fertility |
| Recurrence Risk | After myomectomy, fibroids may recur, but risk is lower for single fibroids | Endometriosis can recur even after excision and requires ongoing management in some cases. |
Endometriosis vs. Fibroid Symptoms
Because symptom patterns can help with early suspicion, here’s a side-by-side comparison:
| Symptom | Uterine Fibroids | Endometriosis |
|---|---|---|
| Pain type | Dull, constant heaviness; sharp pain if a fibroid twists | Severe, cyclical pain before/during periods; deep pain during sex; pain with bowel/bladder |
| Menstrual bleeding | Heavy, prolonged periods (menorrhagia) with clots, can last more than 7 days | May cause heavy bleeding, but more likely irregular spotting; pain often worse than bleeding |
| Bowel/Bladder issues | Frequent urination or constipation due to pressure from large fibroids | Painful urination, diarrhea, and constipation, especially during periods |
| Infertility | Mechanical—blocks tubes, distorts uterus; implantation problems | Inflammatory and anatomical—scar tissue (adhesions), egg quality loss, tube blockages |
| Pain during sex (dyspareunia) | Sometimes, mainly if fibroid is large and pressing on the vaginal walls | Very common, due to scarring and inflammation of pelvic structures |
| Bloating, abdominal swelling | Common if fibroid is large | Cyclical bloating, often called “endo belly” |
| Chronic pelvic pain | Less common unless fibroid is very large | Frequent and severe, can be debilitating |
Key Fact: Many patients have "mixed symptoms," so a proper diagnosis is essential to target the right problem.
Which Is Worse: Endometriosis or Fibroids?
Why this data matters for Indian Patients:
- The 60% Success Benchmark:
Across various centers in Mumbai and South India, the cumulative pregnancy rate following a single, high-quality laparoscopic surgery remains approximately 60%, aligning with your earlier query but with better precision regarding how they conceive.
- Primary Infertility:
The 2025 data show that 68% of Indian women with endometriosis suffer from primary infertility (never having conceived before), emphasizing the need for early intervention.
- Age Factor:
The most successful outcomes in the latest Indian cohorts (2024) were observed in women aged 26 to 30, where the ovarian reserve is still robust enough to overcome endometriosis-related inflammation.
- Overcoming Severe Cases:
Even in the "Low Score" group, the success rate for a live birth reaches 66.6% when using specialized IVF protocols, proving that infertility is not permanent.
Pro Tip: The 2025 data prove that the 'wait and watch' approach is outdated for endometriosis. If your EFI score is high, we give you 6 months for natural joy.
If it's low, we move straight to in vitro fertilization (IVF) treatment to bypass the disease. This targeted approach is why our success rates in Mumbai are now matching global standards.
Understanding these percentages is the first step toward moving from "diagnosis" to "proactive management." Dr. Jay Mehta is a leading endometriosis and fertility specialist in India, known for using these exact clinical benchmarks to help patients avoid unnecessary delays.
At Shree IVF & Endometriosis Clinic, Mumbai, we don't just give you a diagnosis; we give you a score and a clear, data-backed plan to reach your goal of motherhood.

Endometriosis vs. Fibroid Symptoms
This is a frequent question in the clinic, and the answer really depends on your unique symptoms and health goals:
- Pain: Endometriosis usually causes more severe, cyclical pelvic pain, pain with sex, and pain with bowel movements.
- Bleeding: Fibroids more often lead to heavy, prolonged periods, sometimes with large clots.
- Fertility: Both can affect fertility, but endometriosis often damages the ovaries and fallopian tubes, while fibroids physically block or distort the uterus.
- Chronicity: Endometriosis is a chronic inflammatory disease, often recurring even after treatment.
As a doctor, I care most about your personal experience—what is impacting your quality of life and goals? That determines our priorities in treatment.
Are Fibroids and Endometriosis Related?
Yes, there can be a link.
Research suggests that about 30-40% of women diagnosed with one will also develop the other—likely because both are influenced by estrogen and hormones. However, one does not cause the other.
Can Fibroids and Endometriosis Cause Each Other?
No, one does not directly cause the other.
Both conditions can exist independently or together, but having endometriosis does not make fibroids develop, nor vice versa. Their underlying mechanisms are different.
Which Symptoms Overlap Between Fibroids and Endometriosis?
- Heavy or painful periods (dysmenorrhea, menorrhagia)
- Pelvic or lower abdominal pain
- Pain during sex
- Bloating and pelvic pressure
- Difficulty conceiving or infertility
Because of this overlap, a thorough consultation and careful specialist diagnosis are essential before considering treatment.
