Welcome Letter

WES joins forces with EndoDubai for February 2021

The 14th World Congress on Endometriosis was scheduled to be held in Shanghai – but the outbreak of COVID-19 means that we’ve had to change our plans – twice. However, none of our goals and aims have changed for WCE2021, and we have an exciting scientific programme lined up for February – now enhanced with an endoscopy track.

We extend an invitation to join us in Dubai and work with us to “crack” endometriosis and adenomyosis

WES’s World Congresses on Endometriosis have a stellar reputation for delivering science and clinical progress in equal measures. The EndoDubai meetings are top of the league for endoscopy: When science meets surgery – brilliance emerges!

The World Endometriosis Society has, since its inception in 1998, remained committed to collaborative efforts to move the field of endometriosis and adenomyosis forward. These efforts include and involve all stakeholders, and our track record of output, in terms of consensuses on the management of endometriosis, as well as global research directions, speaks for itself.

WCE2021 and EndoDubai2021 will include every single aspect you’d expect a high quality congress on endometriosis and adenomyosis to contain.

We invite you to contribute to “cracking endometriosis and adenomyosis” through your participation in WCE2021 EndoDubai2021 to advance clinical care and research – because that is what the World Endometriosis Society’s work is all about: to improve the lives of all affected women with endometriosis and adenomyosis.

Please help us achieve this goal.

See you in Dubai!

Thank you
