The WHRI and its Leadership Council has been actively advocating for sex inclusion in all levels of research. During the past few months, we sent a letter to NIH Director Dr. Francis Collins on this issue, published two articles, one in Endocrinology and the other in PNAS, and have provided testimony for the Congressional record on this topic. We applaud an announcement made by Dr.Collins and Dr. Janine Clayton, Director, Office on Research in Women’s Health on May 15, to unveil new policies that would require applicants for NIH funds to report their plans for the balance of male and female cells and animals in future preclinical study applications unless inclusion is unwarranted according to defined exceptions. These policies will begin in October 2014. Congratulations to everyone who has worked toward inclusion.
