COSAR is a collaboration of people with a particular interest in adenomyosis and core outcomes. The steering group for COSAR represents patients, gynaecologists with different fields of special interest in adenomyosis, such as imaging, surgery or infertility, researchers, physiotherapist and hormone specialists. All are passionate about improving research on adenomyosis and all are committing to this project in their free time, without any financial gratification.

We are committed to improving the quality of research into adenomyosis and making that research more relevant to women. We have seen the necessity for core outcomes sets in adenomyosis and have seen their success in other gynaecological conditions.
