The article by Ellis and Wood 'A decade to wait' 1 has added to the focus of energies on identifying and reducing the delay in diagnosis of endometriosis for those suffering pelvic pain. Such anonymous, retrospective, self-report surveys have recognised limitations. 2 These endeavours also have an a priori assumption that a shorter time to diagnosis of endometriosis improves outcomes and does not pose risks. Women's health has an unfortunate history of harms caused by assumptions based on 'first principles' without rigorous research. 3,4 The recently formed Endometriosis Initiative Group comprises experts from across the globe with the aim of considering 'alternatives to the commonly accepted hypotheses … and common sense propositions', noting that to do so 'we may need to move away from our "comfort zone" and not become complacent '. 5 In this spirit we propose alternative viewpoints on the effects of reducing delays to diagnosis of endometriosis for women living with pelvic pain, which could be uncomfortable reading for some.
