Males still dominate animal studies

摘要

In the 1990s, several surveys showed a significant sex bias in animal experiments in many biological disciplines, with researchers using a disproportionately high number of male animals. Given that animal models underpin the development of treatments for numerous diseases, this has serious implications for healthcare in women. So, to test whether or not the situation has improved, we recently conducted our own survey of almost 2,000 animal studies that were published in 2009 (ref. 1).
