The Worldwide EndoMarch, a 501(c)(3) nonprofit organization, sponsors Worldwide EndoMarch and World Endometriosis Day events around the world to raise awareness about endometriosis, an incurable and potentially crippling disease that affects about 1 in 8 women and girls. That amounts to roughly 200 million people, which is about ten times the prevalence of autism.

We "Endo March" so that we can get the word out that endometriosis is not just ‘bad cramps’, but is actually a serious disease with severe medical consequences if left untreated. Please help us end the silence about endometriosis, so millions of women and girls can receive a proper diagnosis, quality medical care, and one day a much-needed cure
