The International Menopause Society 20th World Congress on Menopause runs from 30 September to 3 October 2026 at the Windsor Oceânico Hotel and Congress Center in Rio de Janeiro. It is aimed at clinicians and researchers working in menopause, gynaecology, endocrinology, general practice, midwifery and related women's health fields. The published timetable includes plenary lectures, symposia, meet-the-expert sessions, oral communications, CAMS sessions, poster sessions, award sessions, a welcome reception and a closing ceremony. Abstract submission is open for posters and oral presentations. Topics include general menopause, genitourinary syndrome of menopause, hormones and metabolism, sexual function, cardiovascular health, brain and mood, musculoskeletal health, breast health, gynaecology, oncology and other health issues. The oral-presentation deadline is 26 May 2026 and the poster deadline is 22 June 2026; accepted speakers must register by 21 July 2026. Registration information confirms early-bird, regular, late and on-site rate periods, but the actual fees require account login, so visible price fields have not been captured. The venue page gives the congress location in Barra da Tijuca and points delegates to the official travel and accommodation partner.
