Welcome to the OSSD!

The Organization for the Study of Sex Differences (OSSD) is a scientific membership organization that seeks to enhance knowledge of sex/gender differences by facilitating interdisciplinary communication and collaboration among scientists and clinicians of diverse backgrounds.

Most diseases differ in males and females. Often, one sex is partially protected from a disease because of biological or environmental factors. It is important to understand these sex differences, to discover and enhance sex-biasing factors that protect from disease, and to develop optimal therapies for women and men.

The OSSD was founded in 2006 by member scientists and staff of the Society for Women's Health Research (see History). From 2006-2012, OSSD operated as a program of the SWHR, and in 2012 became an independent non-profit educational organization. The OSSD gratefully acknowledges the efforts of the SWHR in the creation, staffing, and funding of OSSD in its early years and recognizes the integral leadership role of SWHR in promoting the study of sex differences and advocating for sex difference research since 1990.
