In 2006, SWHR established the Organization for the Study of Sex Differences (OSSD), the only scientific membership society in North America dedicated to promoting interdisciplinary research on biological sex differences. OSSD was designed to enhance the knowledge of sex and gender differences that impact health by facilitating interdisciplinary communication and collaboration among scientists and clinicians of diverse backgrounds.

OSSD became an independent organization in 2012 but still recognizes the integral leadership role of SWHR in promoting the study of sex differences and advocating for sex differences research since 1990. Members include basic and clinical scientists from various disciplines who share an interest in exploring sex/gender differences in all areas of biological, medical, and behavioral science.

OSSD’s Goals are:

  • to facilitate interdisciplinary research on sex/gender differences at all levels of biological organization;
  • to advance the understanding of sex/gender differences by bringing together scientists and clinicians of diverse backgrounds;
  • to encourage the application of new knowledge of sex/gender differences to improve health and health care; and
  • to promote the field of sex/gender differences research through education, mentoring, and outreach.

SWHR continues to publish Biology of Sex Differences (BSD), the official journal of OSSD.It is an open access, peer-reviewed, online journal published by BioMed Central that publishes articles concerning the role of sex and gender in normal traits and disease. BSD serves as a forum for discussion of the forces that make females and males different, and the downstream pathways that are affected by sex-specific forces. Thomson Reuters has assigned BSD an impact factor of 4.84 for 2014. BSD is ranked 13 out of 163 Biomed Central journals tracked by Thompson Reuters.  BSD ranks in the top quartile of journals in the Thompson Reuters-defined fields of Endocrinology & Metabolism (22/128) and Genetics & Heredity (28/167).
