Endometriosis: Symptoms, Diagnosis, Fertility and Treatment

Endometriosis is a chronic condition in which tissue similar to the lining of the uterus is found outside the uterus. It can involve the pelvic lining, ovaries and deeper structures and may contribute to inflammation, scarring and pain. Symptoms and anatomical extent do not match neatly; severe pain can occur with limited visible disease and extensive disease can sometimes cause few symptoms.

There is no single explanation for why endometriosis develops. It is not caused by poor hygiene, lifestyle failure or delaying pregnancy. Care focuses on reducing symptoms, protecting function, addressing fertility goals and supporting quality of life over time.

Possible symptoms include period pain that disrupts usual activity, chronic pelvic pain, deep pain during or after sex, and bowel or urinary symptoms that become worse around menstruation. Some people seek care because conception is delayed. Pain outside the menstrual period does not rule the condition in or out.

Keep a symptom diary with timing, severity, bleeding, bowel or bladder changes, medicine use and effect on work or sleep. Sudden severe pain, fainting, fever, very heavy bleeding or possible pregnancy complications needs urgent assessment because other conditions may cause similar symptoms.

Assessment includes symptom, menstrual, pregnancy, surgical and family history. With consent, abdominal or pelvic examination may be offered. Current guidance supports ultrasound in suspected endometriosis to identify endometriomas, deep disease and other causes of symptoms. Transabdominal imaging is an alternative when transvaginal ultrasound is declined or unsuitable.

A normal examination or ultrasound does not fully exclude endometriosis. Specialist ultrasound or MRI can help map suspected deep disease. Imaging quality and the experience of the clinician interpreting it matter. CA-125 should not be used to diagnose endometriosis.

Laparoscopy allows a surgeon to inspect the pelvis and may include biopsy or treatment. It can be considered when symptoms persist, imaging is normal but suspicion remains, treatment decisions require more information, or surgery may address known disease. It is not mandatory for each person before any care begins.

Surgery has potential benefits and risks, and repeated ovarian surgery can matter for ovarian reserve. Before proceeding, discuss what question the operation aims to answer, whether treatment will be performed at the same time, the surgeon’s expertise and how results could change the plan.

Pain-relief medicines and hormonal treatments are commonly used to reduce endometriosis-related pain. Options depend on medical history, side effects, contraception needs and whether pregnancy is being attempted. Hormonal suppression does not improve conception while it is preventing ovulation, so fertility goals must be clear.

Treatment response is monitored through symptoms and function rather than assuming one medicine suits each person. Physiotherapy, pain-management support and mental-health care can be useful parts of multidisciplinary treatment. Supplements or herbal products should not replace evidence-based evaluation.

Surgery may remove or destroy lesions, release adhesions or treat an endometrioma. Deep disease involving the bowel, bladder or ureter should be referred to an appropriately experienced multidisciplinary service. Symptom improvement can occur, but recurrence or persistent pain is possible, and surgery does not permanently eliminate the condition.

Long-term plans may combine symptom treatment, follow-up, fertility planning and care for pelvic-floor or pain-related effects. Decisions should reflect what matters most now and can change as life circumstances change. Pregnancy should not be recommended as a treatment for the condition.

Endometriosis can affect fertility through pelvic anatomy, inflammation, ovarian involvement or other mechanisms, but many people conceive without assisted treatment. Evaluation still includes the other partner and other fertility factors. Age, duration of trying, tubal status, ovarian reserve, sperm and previous surgery guide the discussion.

Options may include continued trying, surgery in selected circumstances, IUI or IVF. Medical suppression is used for pain but does not create conception during treatment. Decisions about an endometrioma require care because surgery may affect ovarian tissue. A fertility and endometriosis plan should be coordinated rather than developed in separate silos.

If pregnancy is not an immediate goal, ask how symptom treatment and fertility preservation considerations fit together. Fertility preservation is not routinely required for each person with endometriosis, but it may be discussed when ovarian surgery, age or other factors create concern. Counselling should explain uncertainty and costs without pressure.

Pain and fertility goals can conflict; a treatment that helps pain may pause attempts to conceive, while fertility treatment may not resolve pain. Naming both priorities helps the team sequence care. Referral between gynecology, fertility, imaging and pain services should preserve one shared plan rather than asking the patient to coordinate everything alone.

Return for review if symptoms change, treatment side effects are difficult, conception is delayed or the current plan no longer matches your priorities. Long-term care is more effective when decisions can be revisited without treating a change of preference as inconsistency.
