The Endometriosis Foundation

Endometriosis affects 1 in 10 females, including women, girls, and gender-diverse individuals, yet it remains widely misunderstood. ​Despite its prevalence, diagnosis takes an average of 8 years and 10 months. 8 years of pain, confusion, and feeling unheard. We believe everyone deserves better.

At TEF, our mission is to raise awareness, provide support, and drive meaningful change. We’re committed to breaking the silence, reducing diagnosis times, and advocating for better treatments, funding, and recognition in healthcare. Guided by experts and those with lived experience, every step we take is driven by purpose and impact.

But we can’t do it alone. Take on a 5K or 10K challenge and help us amplify our voice. Together, we can ensure endometriosis is no longer misunderstood or overlooked—because change starts with us.
