The Canadian Oncology Sexual Health Initiative (COSHI) is a growing team of multidisciplinary specialists in oncology-focused sexual health care, which includes leading Cancer Centres across the country. Founded in 2020, COSHI is committed to advancing clinical care and research that support the sexual health and well-being of cancer patients and their partners.
Recognizing that sexual dysfunction consistently involves biological and psychosocial elements, our team of experts consists of urologists, oncologists, psychologists, nurses, pelvic floor physiologists, and patient and partner advocates.
Our mission is to ensure that all individuals affected by cancer—regardless of diagnosis, sexual orientation, or socio-cultural background—have access to evidence-based sexual health care.
Through nationwide collaboration, COSHI aims to advance clinical practice by developing standardized treatment protocols, establishing accessible resource hubs, and creating cancer-specific clinical guidelines.
In parallel, we are committed to driving research by building a national outcomes registry, developing tailored assessment tools, and securing collaborative funding—ultimately enhancing the long-term quality of life for patients and their partners.
Our goal is to create a comprehensive, centralized hub of information that is:
From understanding treatment side effects to rebuilding intimacy and providing clinical guidelines for professionals, COSHI is your trusted partner in navigating the journey of sexual health after a cancer diagnosis. Our goal is to close the significant gap in sexual health care across Canada. We are particularly focused on improving the quality and accessibility of care, ensuring it is inclusive, culturally sensitive and affirming of all sexual orientations.
The Canadian Oncological Sexual Health Initiative is made possible through the generous support of our sponsors.
