The question in focus

A medically grounded guide to endometriosis symptoms, diagnosis, pain treatment, fertility care and multidisciplinary support.

Evidence at a glance

190M

reproductive-aged women are estimated to live with endometriosis worldwide

WHO estimates prevalence at about 10%. The figure describes population burden, not the likelihood that any one symptom is endometriosis. [1]

Endometriosis

Endometriosis is a chronic, variable disease

Endometriosis is characterized by tissue resembling the lining of the uterus outside the uterus, commonly in the pelvis but sometimes elsewhere. WHO estimates that it affects about 10% of reproductive-aged women, approximately 190 million people worldwide. Symptoms can include severe period pain, chronic pelvic pain, heavy bleeding, pain with sex, bowel or urinary pain, fatigue and infertility. Some people have limited symptoms despite extensive disease. [1]

Pain severity does not reliably map to disease stage, and symptoms overlap with adenomyosis, fibroids, irritable bowel syndrome, bladder pain, pelvic floor dysfunction and other conditions. A careful history should explore timing, location, bowel and bladder symptoms, sex-related pain, fertility goals, school or work impact and previous treatments without normalizing disabling pain.

  • Severe pain that disrupts daily life deserves assessment.
  • A normal pelvic examination does not rule out endometriosis.
  • The condition can affect adolescents as well as adults.

Diagnosis no longer requires automatic laparoscopy

ESHRE's 2022 guideline changed the role of diagnostic laparoscopy. Ultrasound or MRI can identify ovarian endometrioma and some deep disease, while negative imaging does not exclude superficial endometriosis. Empirical hormonal treatment and imaging can be considered alongside laparoscopy, with discussion of benefits, limitations and individual preference. [2]

Laparoscopy remains appropriate when imaging is negative but empirical treatment is unsuccessful or unsuitable, when surgery is needed for treatment, or when diagnosis will materially change care. NICE recommends specialist referral for suspected endometrioma, deep endometriosis or disease outside the pelvic cavity. [3] Histology can support diagnosis, although a negative sample does not always exclude disease.

  • Use clinicians trained in endometriosis-focused ultrasound where available.
  • Do not use a negative scan as proof that symptoms are not real.
  • Explain whether surgery is intended to diagnose, treat or both.

Pain care should be stepped and preference-sensitive

Treatment aims to reduce symptoms and support quality of life; there is currently no cure. Options can include analgesia, combined hormonal contraception, progestogens and other hormone-suppressing therapies. Choice depends on symptoms, contraindications, adverse effects, pregnancy goals and access. ESHRE recommends several hormonal options for pain while emphasizing shared decisions, and Cochrane evidence syntheses document uncertainty across parts of the treatment pathway. [2][4]

Surgery can remove lesions and adhesions, but benefits and recurrence risk vary with disease location, prior operations and surgeon expertise. Repeat surgery is not automatically the best response to recurrent pain. Pelvic floor physiotherapy, pain medicine, psychological support and management of bowel, bladder or musculoskeletal contributors may be useful within multidisciplinary care, even when they do not remove lesions.

  • Set a measurable treatment goal such as sleep, mobility or reduced pain days.
  • Review side effects and response after an agreed interval.
  • Refer complex deep disease to an experienced multidisciplinary service.
  • Avoid presenting hysterectomy as a guaranteed cure.

Fertility decisions are distinct from pain decisions

Endometriosis is associated with infertility, but many people conceive without assisted treatment. Evaluation should consider age, ovarian reserve when relevant, semen, tubal factors, disease location, previous surgery and duration of infertility. Surgery before fertility treatment is not universally beneficial and can reduce ovarian reserve when an endometrioma is operated on.

ESHRE advises against routine surgery for ovarian endometrioma before assisted reproduction solely to improve live birth, because evidence does not show benefit and surgery may harm ovarian reserve. [2] ASRM similarly recommends individualized decisions based on symptoms, age, fertility factors and surgical risk. [5] Fertility preservation may be discussed in selected cases, but it is not a guarantee.

  • Clarify whether the immediate goal is pain relief, spontaneous conception or assisted reproduction.
  • Discuss ovarian-reserve implications before ovarian surgery.
  • Coordinate the surgeon and fertility specialist before irreversible decisions.

Good care measures life impact, not lesions alone

Endometriosis can affect education, work, relationships, sexual wellbeing and mental health. WHO highlights depression and anxiety among possible impacts. [1] Follow-up should assess function, treatment burden, fertility priorities and signs of other diagnoses. Psychological care should never be used to imply that pain is imagined; it can support coping, trauma, sleep and the consequences of chronic illness.

Research on diagnostic delay varies by country, study design and definition, so a universal ten-year claim is not defensible. A systematic review found wide variation and substantial heterogeneity in reported delays. [6] The more useful service measures are time from first presentation to appropriate assessment, access to specialist imaging, treatment response, unplanned care and patient-reported functioning.

  • Record symptom onset, first help-seeking and key diagnostic steps.
  • Offer adolescent-appropriate and culturally sensitive care.
  • Provide clear routes back when symptoms change or treatment fails.
  • Measure whether the person can live the life that matters to them.

What the evidence cannot yet answer

  • Population prevalence estimates cannot diagnose an individual.
  • Negative imaging does not exclude superficial disease.
  • Comparative evidence is limited for several combinations and sequences of treatment.
  • Reported diagnostic-delay averages vary widely and should not be presented as a universal fixed number.

Questions worth taking into care

  1. Have symptoms and functional impact been documented over time?
  2. Was imaging performed and interpreted by appropriately trained clinicians?
  3. Are pain, fertility and long-term health goals being considered separately?
  4. Have benefits and risks of surgery, including ovarian reserve, been discussed?
  5. Is multidisciplinary support available when pain has several contributors?

This evidence synthesis is for general information. It does not diagnose a condition or replace care from a qualified health professional. Treatment choices depend on individual history, examination, local guidance and informed preference. Emergency or rapidly worsening symptoms need urgent local medical assessment.
