Welcome Letter

Dear Colleagues,

Earlier in the year, we promised to deliver WCE2021 no matter what – and we are! The science is too good not to share – so we are delivering!

However, after careful consideration, we must deliver the 14th World Congress on Endometriosis virtually.

We feel, with all the uncertainty around us, that this is the most responsible way for us all to “come together”. After all, the health and safety of all of you (and the entire community) is of the utmost importance and is what drove our decision at this time.

Whilst we won’t get to meet in person, we are committed to deliver an outstanding scientific programme and to provide a virtual experience that is accessible worldwide enabling participants to access the latest research and progress in endometriosis through a new format – both live and in your own time. There will be plenty of networking opportunities as well – we need these brain exchanges to fulfil our joint commitment to progress the field of endometriosis.

See you online from 6 – 10 March 2021.


Sun-Wei Guo, PhD
Joint WCE2021 President

Sponsors & Exhibitors

The World Congresses on Endometriosis (WCE) are made possible because of our longstanding partnerships with sponsors, exhibitors, and collaborators. The World Endometriosis Society (WES) is appreciative of this ongoing support and collaboration, which enables us to move the field of endometriosis and adenomyosis forward together.

Sponsoring the 14th World Congress on Endometriosis provides:

  • Outstanding access to the key international experts in the clinical management and scientific research of endometriosis, adenomyosis, and other uterine disorders
  • Extensive global marketing visibility to >1200 delegates
  • Ongoing website visibility with a direct link to your website
  • Opportunities to identify cutting edge topical issues: clinical, pre-clinical, and research and development
  • Establishment of relationships with the current and future leaders in the field of endometriosis, adenomyosis, and other uterine disorders

General Information

Pre/Post-Congress Adventures

Presentation Guidelines

All presentations and posters must be in English. All oral presentations will be pre-recorded.


Preparing your presentation slides

  • Use your allocated time wisely: therefore, please avoid using introductory slides on definitions, descriptions, and/or impact of endometriosis, as all congress participants know these facts already.
  • Your presentation should be prepared in Microsoft PowerPoint in English. If you are preparing slides on a Mac, please ensure your slides are compatible with MS PowerPoint.
  • The file size should be 25MB maximum.
  • The format of the PowerPoint presentation should be in widescreen (16:9).
  • The abstract title, author(s), and affiliation(s) should appear on the first slide (the second slide must contain a disclosure statement for the presenting author), a requirement by the CME accrediting organisation.
  • Logos of any for-profit organisation should not appear in the presentation slides.

Preparing your poster

  • You have the option to submit your poster in PDF or MP4 (slides + narration) format. The file size should be 25MB maximum.
  • All posters must be created using PowerPoint with a maximum of 7 slides (including title/author slide). PowerPoint presentations should be in widescreen (16:9).
  • Text and illustrations should be easily readable: use high-contrast colours for the best definition of your text.
  • Posters should be self-contained and self-explanatory.
  • The abstract title, author(s), and affiliation(s) should appear on the first slide, and must include disclosures.
  • Logos of any for-profit organisation should not appear in the presentation slides.

Poster presenters have the option to add a maximum 3-minute narration as part of their poster. This can be prepared directly through PowerPoint. Watch this training video for recording instructions. Posters with narration should be saved and uploaded as an .mp4 file. Please only upload one file (.pdf OR .mp4). The file size should be 25MB maximum.
