Almost a decade. It is the temporal abyss that, on average, a woman in Catalonia must cross before discovering that the pain she suffers is not "what is expected", but a disease that has a name: endometriosis. Currently, one in ten Catalan women live with this chronic and inflammatory pathology that hijacks their physical and emotional health in the face of the historical normalization of female pain. For Dr. Francisco Carmona, head of gynecology at the Hospital Clínic and an international reference in the field, the label "silent disease" is a trap. In reality, it has been a pathology silenced by a gender bias in scientific research. His statement could not be more graphic: "If men had testicular pain five days a month, the world would have stopped years ago".

Laia Casas is a biophysician, sexologist, and vice president of EndoCat, the endometriosis patient association, a disease she suffers from and tries to raise awareness about to break the silence surrounding it.

Gender bias in medicine translates into invisible diseases, such as endometriosis, lipedema or fibromyalgia, suffered by women like Idoia, Marian and Gisela. But also the medicalisation of normal physiological processes such as pregnancy or childbirth, as Cristina relates. The four of them raise their voices and demand that research and medicine also put women at the centre.
