An enlarged ovary means one or both ovaries are bigger than usual. It is not a single disease—it is a sign that can happen for many reasons. The most common reason is a cyst (a small fluid-filled sac), which often forms naturally during the menstrual cycle and usually disappears on its own. Other reasons include polycystic ovary syndrome (PCOS), endometriosis (blood-filled “chocolate” cysts called endometriomas), infection and tubo-ovarian abscess, ovarian torsion (the ovary twisting on its blood supply), hormone-related changes (like early pregnancy or fertility medicines), and much less commonly benign or malignant tumors. The goal of care is to figure out why the ovary is enlarged, whether you need urgent treatment, and how to protect future fertility and overall health. ACOG

Your ovaries are two small organs in the lower belly (pelvis). They store eggs and make hormones. An enlarged ovary means an ovary is bigger than expected for age and life stage. Size changes during life. In girls and people who still ovulate, ovaries are a bit larger; after menopause, they naturally shrink. Doctors often estimate size by volume on ultrasound. Typical average volumes in adults who are not post-menopausal are around 6–7 mL, with upper normal limits that gradually decline with age; after menopause, smaller volumes are expected (about ≤10 mL is commonly used as a practical upper limit). These numbers are guides, not hard rules, and doctors always interpret them with the full picture (symptoms, exam, and imaging details). RadiopaediaPubMed
Why an ovary looks large depends on what fills or expands it. Common reasons include:
Fluid (like a simple cyst),
Blood (a bleeding cyst),
Thick “chocolate” fluid (an endometrioma from endometriosis),
Fat, hair, or other tissue (a dermoid/teratoma),
Extra follicles (as in PCOS),
Solid tumor tissue (benign or malignant),
Infection and pus nearby (a tubo-ovarian abscess),
Swelling from a twist of its blood supply (ovarian torsion),
Hormone stimulation (fertility treatment).
Ultrasound—especially transvaginal ultrasound—is the first test doctors use to see why an ovary is enlarged because it shows size, shape, and inside details safely and well. PMCThe ObG Project
Types of ovarian enlargement
By side
Unilateral: only one ovary is enlarged (e.g., a cyst, torsion, dermoid).
Bilateral: both ovaries are enlarged (e.g., PCOS, theca-lutein cysts, OHSS, metastatic disease).
By contents
Cystic: mostly fluid (simple follicular cyst, corpus luteum, theca-lutein cysts, serous or mucinous cystadenoma).
Solid: mostly tissue (fibroma, thecoma, some tumors).
Complex/mixed: both solid and fluid parts (endometrioma, hemorrhagic cyst, dermoid, abscess).
By cause
Physiologic/functional: normal monthly changes (follicular or corpus luteum cysts).
Inflammatory/infectious: pelvic inflammatory disease leading to a tubo-ovarian abscess.
Hormonal: PCOS, fertility drug response (OHSS).
Neoplastic (tumor)
Benign: e.g., dermoid, cystadenoma, fibroma.
Malignant: ovarian cancer (various subtypes).
Vascular/edematous: ovarian torsion with congestion and swelling, massive ovarian edema.
Pregnancy-related: luteoma, theca-lutein cysts.
By timing
Acute: sudden swelling and pain (torsion, hemorrhagic cyst, abscess).
Chronic: slow growth or long-standing fullness (endometrioma, benign tumors, PCOS).
By life stage
Reproductive age: functional cysts are common; PCOS is common; pregnancy-related changes possible.
Postmenopausal: functional cysts are uncommon; any enlargement deserves careful assessment.
Common causes
Functional (follicular) cyst
A normal egg follicle keeps growing and fills with fluid. It is the most common benign cause and often shrinks on its own in a few months.Corpus luteum cyst
After ovulation, the empty follicle forms the corpus luteum; sometimes it seals and fills with fluid or blood and looks enlarged, often with mild pain.Hemorrhagic cyst
A cyst bleeds internally. It may cause sudden pain. On ultrasound it looks complex but often resolves over time.Endometrioma (“chocolate cyst”)
Endometriosis tissue bleeds over and over inside a cyst in the ovary, making thick brown fluid. It often causes chronic pelvic pain and period pain.Polycystic ovary syndrome (PCOS)
Hormone imbalance leads to many small follicles and sometimes larger ovarian volume (≥10 mL is a threshold used in criteria when high-quality ultrasound is available). Ovaries can appear “string of pearls” on ultrasound. PMCMature cystic teratoma (dermoid)
A benign tumor that may contain fat, hair, or bone. It grows slowly and can enlarge the ovary. Rarely it can twist the ovary.Serous cystadenoma
A benign, thin-walled, water-filled cyst. It can become quite large and still be benign.Mucinous cystadenoma
A benign cyst filled with thicker mucous-like fluid. It can reach very large sizes.Ovarian torsion
The ovary twists on its stalk, cutting off blood flow. It swells from congestion and can become large and tender. It’s an emergency needing urgent care. On ultrasound, a “whirlpool sign” of the twisted pedicle can help confirm the diagnosis. PMCPubMedTubo-ovarian abscess (TOA)
A severe infection often related to pelvic inflammatory disease forms a pocket of pus involving the ovary and tube, causing enlargement, fever, and pain. CDCTheca-lutein cysts
Multiple large cysts caused by high pregnancy hormones or fertility drugs. They may enlarge both ovaries and usually settle when hormone levels drop.Ovarian hyperstimulation syndrome (OHSS)
An exaggerated response to fertility treatment makes both ovaries very cystic and enlarged with fluid shifts in the body.Pregnancy luteoma
A benign overgrowth of ovarian cells during pregnancy that can enlarge the ovary and usually shrinks after delivery.Fibroma / Thecoma (stromal tumors)
Solid benign tumors from the ovary’s supporting tissue. They can enlarge the ovary and sometimes cause fluid in the abdomen.Granulosa cell tumor
A rare hormone-producing tumor that can enlarge the ovary and cause bleeding or thickened uterine lining.Epithelial ovarian cancer
A malignant tumor starting on the ovary’s surface cells. It may present with an enlarged, complex ovary plus symptoms like bloating and early fullness.Metastatic (“Krukenberg”) tumor
Cancer from another organ (often stomach or colon) spreads to the ovary, enlarging it—often both sides.Massive ovarian edema
Poor outflow of venous/lymph fluid (sometimes from intermittent torsion) makes the ovary swell like a sponge.Paraovarian or paratubal cyst
A cyst next to (not in) the ovary can make the adnexal region look enlarged. Ultrasound helps tell it apart.Severe, untreated hypothyroidism (rare)
In rare cases (e.g., Van Wyk–Grumbach syndrome), low thyroid hormone can lead to large, cystic ovaries due to hormonal feedback changes.
Symptoms
Pelvic or lower belly pain (dull, crampy, or sharp).
A feeling of fullness or pressure low in the belly.
Bloating or swelling of the abdomen.
Period changes (heavier, lighter, or irregular).
Missed periods or fewer periods (often with PCOS).
Pain during sex (deep pelvic pain).
Pain with exercise or sudden movement, especially if a cyst pulls or a torsion happens.
Sudden severe one-sided pain with nausea/vomiting (warning sign for torsion—emergency).
Fever, chills, and pelvic pain (suggests infection/abscess—urgent).
Needing to pee more often (pressure on the bladder).
Constipation or trouble passing stool (pressure on the bowel).
Early fullness when eating or loss of appetite (when large masses take up space).
Unplanned weight loss, fatigue, or persistent bloating (possible cancer signs—see a doctor).
Breast tenderness or spotting (hormone-active cysts or tumors).
Acne or extra hair growth (androgen effects, often with PCOS).
Emergency red flags: sudden severe pain, vomiting, fainting, high fever, rigid abdomen—call emergency services to rule out torsion, rupture, or abscess.
Diagnostic tests
A) Physical exam
Vital signs and general check
Fever suggests infection; fast heart rate and low blood pressure suggest severe pain, bleeding, or sepsis.Abdominal exam
The clinician gently presses on the belly to find tenderness, guarding, rebound, or a mass.Pelvic speculum exam
Looks for discharge, bleeding, and the health of the cervix and vagina. Helps identify signs of infection.Bimanual pelvic exam
One hand inside the vagina and one on the belly to feel ovary size, tenderness, and mobility. It’s an estimate—imaging confirms size.
B) Manual/bedside maneuvers
Cervical motion tenderness (CMT) test
Moving the cervix causes sharp pain if the pelvic lining, tubes, or ovary are inflamed—as in PID/TOA.Psoas sign
Pain with hip extension suggests irritation near the appendix; helps separate appendicitis from gynecologic pain.Obturator sign
Pain with internal rotation of a bent hip also points toward pelvic/appendix irritation; another “look-alike” screen.Carnett sign
If belly pain worsens when tightening the abdominal wall, the pain may come from the abdominal wall, not the ovary (helps avoid mislabeling).
These bedside maneuvers do not diagnose ovarian enlargement directly. They help differentiate gynecologic from non-gynecologic causes of pelvic pain.
C) Lab and pathological tests
Pregnancy test (urine or serum β-hCG)
Always done first in people who could be pregnant, because pregnancy changes the plan (and causes like ectopic pregnancy can mimic ovary pain).Complete blood count (CBC)
High white cells suggest infection; anemia suggests bleeding from a ruptured cyst.Vaginal/cervical swabs for NAAT (gonorrhea, chlamydia, and other pathogens)
Confirms PID, a common cause of a tubo-ovarian abscess. CDCTumor marker panel when a mass looks suspicious
Examples: CA-125, HE4, AFP, β-hCG, LDH, Inhibin, estradiol or testosterone depending on the suspected tumor type. These markers do not diagnose cancer alone; they refine risk and help triage to a gynecologic oncologist. AAFPThyroid function tests
Check for hypothyroidism in rare presentations of large, cystic ovaries.Reproductive hormone panel
FSH/LH, AMH, prolactin, testosterone—useful when PCOS or ovulation issues are suspected. (PCOS criteria sometimes use ovarian volume ≥10 mL on high-quality ultrasound.) PMCHistopathology (tissue diagnosis)
If surgery is done, microscopic exam confirms the exact cyst or tumor type and guides final treatment.
D) Electrodiagnostic tests
Electrocardiogram (ECG)
Not a test for the ovary itself, but used if someone is very unwell or heading to surgery, or to evaluate fast heart rate from severe pain or infection. (Electrodiagnostic studies are rarely needed for ovarian conditions; included here for completeness.)
E) Imaging tests
Transvaginal pelvic ultrasound (TVUS)
First-line test. It estimates ovarian volume, shows whether the mass is cystic, solid, or complex, checks internal features (septa, nodules), and looks for free fluid. Color Doppler adds blood-flow info (reduced/absent flow raises concern for torsion). PMCThe ObG ProjectTransabdominal pelvic ultrasound
Helpful when the mass is very large or when TVUS is not feasible; complements TVUS by viewing higher in the abdomen. The ObG ProjectPelvic MRI
Gives very detailed images that help tell apart endometrioma, dermoid, fibroma, and malignant features when ultrasound is uncertain.CT scan of abdomen and pelvis
Less ideal for simple ovarian cysts, but useful in emergencies (sudden severe pain) or when doctors need to look broadly for infection, bleeding, bowel disease, or cancer spread.
Non-pharmacological Treatments
These are supportive tools your clinician may suggest depending on the cause. They do not replace medical evaluation, especially for severe pain, fever, pregnancy, or postmenopause.

Drug Treatments
Always use medicines under a clinician’s guidance; doses below are typical adult ranges and may need adjustment.
NSAIDs (e.g., ibuprofen, naproxen) – Analgesic/anti-inflammatory
Dose/time: Ibuprofen 400–600 mg every 6–8 h as needed; naproxen 250–500 mg twice daily with food.
Purpose: Pain from functional or hemorrhagic cysts.
Mechanism: COX inhibition → less prostaglandin-mediated pain.
Side effects: Stomach upset/ulcer risk, kidney strain, blood pressure effects.
Note: Symptom relief only; does not “shrink” cysts.
Combined oral contraceptive pills (COCPs) – Estrogen/progestin
Dose/time: One pill daily (e.g., ethinyl estradiol 20–35 µg with a progestin).
Purpose: Regulate cycles, reduce new functional cysts, manage PCOS symptoms.

Side effects: Irregular bleeding, headache, decreased libido.
GnRH agonists (e.g., leuprolide depot 3.75 mg monthly) with add-back
Purpose: Endometriosis pain control; pre-op shrinkage.
Mechanism: Down-regulates pituitary → very low estrogen (“medical menopause”).
Side effects: Hot flashes, bone loss (use short term; add-back therapy reduces side effects).
Aromatase inhibitors (letrozole 2.5–7.5 mg daily for 5 days in ovulation induction; or daily in endometriosis with add-backs)
Purpose: PCOS anovulation (first-line ovulation induction) or refractory endometriosis with supervision.
Mechanism: Lowers estrogen synthesis; lifts negative feedback to induce FSH rise.
Side effects: Headache, hot flushes; risk of multiple pregnancy if used for induction. Oxford Academic
Metformin (500 mg with meals, titrate to 1500–2000 mg/day) – Insulin sensitizer
Purpose: PCOS with insulin resistance; improves cycles and metabolic markers.
Mechanism: Reduces hepatic glucose output; improves insulin sensitivity → lowers ovarian androgen production.
Side effects: GI upset (start low/go slow), B12 lowering (monitor).
Role vs COCP: COCPs for irregular cycles/hirsutism; metformin for metabolic goals. PMC
Antibiotics for PID/TOA (examples; hospital regimens vary)

Regenerative / stem-cell” style options
Important: The items below are not standard treatments for a typical enlarged ovary. Some are experimental and should only occur in research settings with ethics approval.
Intra-ovarian PRP (platelet-rich plasma) – Experimental
Dose/approach: Single or staged ovarian injections in small studies.
Function/mechanism: Growth factors (PDGF, TGF-β, VEGF) may stimulate local tissue repair; evidence is limited.Mesenchymal stem cell therapy (e.g., bone marrow–derived or adipose-derived MSCs) – Experimental
Function/mechanism: Paracrine factors may support follicular niche; early data only; unknown long-term safety.Ovarian tissue cryopreservation and re-implantation – Fertility preservation technique, not for cysts
Function: Restores ovarian hormones/fertility after gonadotoxic therapy in selected patients; not a routine cyst therapy.Growth hormone as IVF adjuvant – Controversial
Function: Proposed to aid poor ovarian responders; mixed evidence.DHEA (dehydroepiandrosterone) pre-IVF – Adjunct
Dose: 25 mg 2–3×/day (specialist-guided).
Mechanism: Androgen priming may enhance folliculogenesis; evidence mixed.Melatonin (antioxidant) in fertility protocols – Adjunct
Dose: 2–3 mg at night in some protocols.
Mechanism: Reduces oxidative stress in follicles; supportive data are small.
Bottom line: These approaches are not used to treat a routine enlarged ovary and should not delay standard, guideline-based care.
Surgeries
Laparoscopic cystectomy (cyst removal, ovary preserved)
Why: For persistent, large, painful, or suspicious benign-appearing cysts; for endometriomas impacting pain/fertility.
What happens: Keyhole surgery; cyst wall is shelled out; ovary is left behind.Laparoscopic detorsion
Why: Emergency for suspected ovarian torsion to restore blood flow and save the ovary.
What happens: Twist is unwound; ovary usually preserved even if dark; cystectomy may be deferred. ACOGLippincott JournalsDrainage or surgery for tubo-ovarian abscess
Why: If large, not improving on antibiotics, or at risk of rupture.
What happens: Image-guided drainage or laparoscopy with washout, plus antibiotics. CDCOophorectomy ± salpingo-oophorectomy (removal of one ovary ± tube)
Why: For masses highly suspicious for cancer or when the ovary is not salvageable.
What happens: Laparoscopic or open; specimen sent for pathology; staging may be needed.Fertility-sparing oncologic surgery
Why: Selected early cancers in young patients.
What happens: Tumor removal with staging while preserving as much fertility potential as safely possible—done by gynecologic oncologists guided by risk systems and tumor markers. ACOG

When to see a doctor
Right now / Emergency: sudden severe one-sided pelvic pain, pain with nausea/vomiting, fainting, fever, rigid abdomen, or pain in pregnancy—these can signal torsion, ruptured cyst with bleeding, or abscess. ACOGCDC
Urgently (within 24–48 h): constant worsening pelvic pain, fever without a clear source, foul discharge, or inability to keep fluids down. CDC
Soon (book a visit): new pelvic pressure/bloating lasting >2–3 weeks, irregular bleeding, difficulty getting pregnant, or a mass found on exam/scan—especially after menopause. RCOG
What to eat & what to avoid
What to eat
Plenty of vegetables and fruits (aim half the plate).
High-fiber carbs (oats, beans, lentils, brown rice) for steadier insulin.
Lean proteins (fish, eggs, poultry, tofu) to support tissue repair.
Healthy fats (olive oil, nuts, seeds) for anti-inflammatory benefits.
Fermented foods + fluids (yogurt, kefir, water) for gut and bowel comfort.
What to limit/avoid
- Ultra-processed sweets and sugary drinks that spike insulin (PCOS).
- Trans fats and excessive fried foods that promote inflammation.
- Heavy alcohol (worsens sleep, hormones).
- Smoking/nicotine (hurts healing and vessels).
- Very vigorous, jarring activity during acute pain/torsion risk period (temporary avoidance).
FAQs
Is an enlarged ovary always dangerous?
Most are benign (often cysts) and settle with time. The key is to rule out emergencies (torsion, abscess) and cancer in higher-risk groups. ACOGCan a simple cyst go away on its own?
Yes—many functional cysts disappear within 1–2 cycles; follow-up ultrasound confirms. ACOGHow do doctors decide if a mass looks risky?
Ultrasound features are scored with systems like O-RADS and IOTA; results guide observation vs surgery and referrals. American College of RadiologyPMCWhat size is worrying?
It’s not just size. Complex features (solid parts, papillary projections, high blood flow, ascites) matter. Postmenopausal simple cysts <~5 cm with normal CA-125 often can be watched; policies vary by guideline. RCOGRACGPDoes PCOS mean my ovaries are packed with cysts?
They’re packed with small follicles, not big cysts. PCOS is a hormone-metabolic condition, not just an ultrasound picture. PMCCan birth-control pills shrink existing cysts?
They help prevent new functional cysts; existing simple cysts usually resolve on their own with time. ACOGCan an enlarged ovary affect fertility?
Sometimes—e.g., endometriomas, PCOS, or torsion can impact fertility; many benign cysts do not.When is cancer suspected?
Suspicious ultrasound features, elevated tumor markers (context-dependent), persistent growth, or postmenopausal symptoms prompt referral/staging. CA-125 alone cannot diagnose cancer. nccn.orgPMCWhat is torsion and why is it urgent?
The ovary twists, cutting blood flow. Classic signs: sudden severe one-sided pain with nausea/vomiting. Surgery to detorse and preserve the ovary is recommended. ACOGHow are infections like TOA treated?
Broad-spectrum IV antibiotics followed by oral therapy for a total ~14 days; drainage/surgery if not improving. CDCWhat’s O-RADS vs IOTA?
Both are ultrasound-based risk systems. O-RADS provides management categories; IOTA provides validated rules and risk models; both aim to improve accuracy and consistency. American College of RadiologyRadiology Published JournalsWill I always need surgery?
No. Many cysts are watched. Surgery is for persistent, symptomatic, large, or suspicious masses—or emergencies. ACOGWhat about supplements?
Some (e.g., inositol, vitamin D) may help PCOS/metabolic aspects; discuss with your clinician—supplements can interact with medicines.How often should I repeat scans?
Commonly 6–8 weeks for simple cysts; schedule varies by size, features, and guideline. Follow your clinician’s plan. ACOGCan I exercise?
Yes—prefer low-impact until the cause is clear; avoid jarring moves if a large cyst/torsion risk is present (short-term precaution).
