What World Endometriosis Society does

World Endometriosis Society (WES) is an international non-profit scientific medical society founded in 1998 in Quebec, Canada, by Professors Jacques Donnez and Rodolphe Maheux (the latter served as President from 2005 until his death in 2007). WES advances evidence-based standards for education, advocacy, clinical care, and research in endometriosis and adenomyosis, in collaboration with global stakeholders including WHO, NIH, EU, and partner societies such as ESHRE and ESGE. The organisation is registered in Canada (non-profit number 354079-1) and serves healthcare professionals, researchers, students/trainees, patient advocates, and patient support organisations across more than 22 countries, supported by over 50 ambassadors globally.

WES's portfolio includes core services such as the WES Mentoring Programme (a 12-month virtual scheme for early-career researchers), WESinars (educational webinars), the biennial World Congress on Endometriosis (flagship international congress held every two years: Sydney 2025, Istanbul 2027, planned 2029), research grants (Early Career Investigator Awards at $20,000 CAD each, six annually), travel grants (Rodolphe Maheux Travel Grant), and recognition awards (David Healy Award for best scientific presentation; Rodolphe Maheux Award for best clinical presentation). WES also co-develops clinical guidelines, including the WES-ESHRE-ESGE Good Practice Recommendations for Adenomyosis.

WES operates a community-led go-to-market model. Revenue is generated from two disclosed streams: membership dues ($150 CAD regular, $120 CAD retired, $90 CAD student, billed on a two-year cycle from 01 March 2026 to 29 February 2028, with Canadian GST applied) and a share of revenues from the biennial World Congress. Donations channel through WERF (World Endometriosis Research Foundation) for research support. Distribution occurs through the WES membership portal (EventsAir), the WCE, virtual WESinars, and research grant application portals. WES maintains no proprietary technology platform; the core technology field is marked "Not applicable."

Comparable as a membership-based medical society that develops clinical practice guidelines and continuing education for women's health professionals, including endometriosis.

Direct peers

• World Endometriosis Research Foundation (WERF): Closely affiliated research foundation for endometriosis, sharing board members and donation flows with WES. Directly comparable as a disease-specific organization driving research priorities and funding in the same field.
• International Federation of Fertility Societies (IFFS): Global federation representing fertility-focused medical societies. Comparable to WES as a member-based international organization in reproductive medicine, with overlapping clinician communities given endometriosis's impact on fertility.
• European Society of Human Reproduction and Embryology (ESHRE): Europe's leading society in reproductive medicine and embryology.

Comparable to WES as a member-based society running congresses, fellowships, and clinical education in gynecological surgery.
• Society of Endometriosis and Uterine Disorders (SEUD): International scientific society dedicated to endometriosis and uterine disorders, running its own congress and research initiatives. Directly comparable to WES as a disease-specific membership organization in the same field, competing for researchers, sponsors, and congress attendees.

Emerging players

• Endometriosis Foundation of America: U.S.-based nonprofit focused on endometriosis awareness, research funding, and patient advocacy. Comparable to WES as a disease-specific nonprofit operating in the same field, with stronger patient-advocacy orientation but a narrower geographic and scientific footprint.

Regional players

• British Society of Gynaecological Endoscopy (BSGE): UK-based society for gynecological endoscopy with strong endometriosis focus and accredited centers. Comparable to WES as a national/regional medical society running training, accreditation, and congresses in minimally invasive endometriosis care.
