The conference theme, Sexual Health & Rights: A Global Challenge, reflects the 8 priorities of the WAS Declaration for the Millennium and echoes the urgent need for action to ensure sexual health and rights for all. The WAS Congress is held every two years, and brings together the outstanding clinicians, researchers, educators, activists and policy makers from around the globe to share knowledge on the diverse and often controversial issues of contemporary sexual health. Sweden has always played a pioneering role in promoting sexual education, health and equality.
