How these figures are counted
  • Trials on record is every trial tagged to this condition at any stage, except those withdrawn before starting or terminated early. Most are completed rather than ongoing, so this is a measure of research history, not of current activity. It is also smaller than the sitewide "trials tracked" figure, which does include withdrawn and terminated trials.
  • Recruiting now counts only trials whose registry status is "Recruiting". Trials listed as not yet recruiting or enrolling by invitation are excluded, so this understates how many may open to new participants soon.
  • Australian sites counts trials counted under "Recruiting now" that list at least one Australian site. A site being listed does not mean it is currently enrolling, and Australian trials registered only on ANZCTR are not counted yet, so this understates local availability.
  • Phase 3 trials counts trials counted under "Recruiting now" that are at Phase 3.

Understanding Endometriosis

Endometriosis is a condition where tissue similar to the lining of the uterus grows in places it shouldn't, such as on the ovaries, fallopian tubes, or elsewhere in the pelvis. Each month, this tissue responds to hormonal changes in the same way the uterine lining does — it thickens and breaks down — but because it has nowhere to go, it can cause inflammation, scarring, and pain. Symptoms vary a lot from person to person and can include painful periods, pelvic pain, pain during sex, and in some cases, difficulty getting pregnant. Some people have significant symptoms with very little visible disease, while others have extensive endometriosis but few symptoms.

Endometriosis is more common than many people realise. In Australia, it is estimated to affect around one in seven women and people assigned female at birth, meaning roughly 830,000 Australians are living with the condition. Despite how common it is, diagnosis can sometimes take many years, often because symptoms are mistaken for normal period pain or other conditions.

When it comes to managing endometriosis, there is no single approach that works for everyone. Broadly speaking, options generally fall into a few categories: pain relief medications, hormonal therapies that aim to reduce or suppress the menstrual cycle, and surgery to remove or treat areas of endometriosis. Some people also work with a range of health professionals, such as physiotherapists or pain specialists, to help manage their symptoms. A GP or specialist can explain which options might be relevant based on an individual's specific circumstances and health needs.

What the authority types mean Unrestricted: no clinical criteria; a doctor can prescribe it on the PBS for any appropriate use. Restricted benefit: subsidised only for the specific conditions or uses set out by the PBS. Streamlined authority: restricted, but the doctor does not need prior approval; they record a streamlined authority code confirming you meet the criteria.
