medical research gap: a disparity that exists because the vast majority of biological literature is based on single sex studies of males of European ancestry.

Did you know that it wasn't until 1993 that it was required for women to be included in clinical trials? Or that as of 2018, 78% of people included in key genomic research were of European ancestry?

The implications of gender and racial exclusion in medical and scientific research has had huge (negative) implications for the health of us all. It leads to biased data sets that then result in unequal diagnosis and treatment for people of varying backgrounds.

Today on the podcast is Elizabeth Ruzzo, Ph.D., founder of Adyn, a company on a mission to make scientific discovery more inclusive. Adyn recognizes that medical gender and race gaps have profound and devastating impacts on available diagnostics, treatment, and care. To close this gap, Adyn is starting out by using genetic and hormonal info, combined with big data, for a birth control test. This test could tell you the best hormonal birth control method to use for YOUR particular genetic and hormonal makeup. It's precision medicine that not only will help the individual accessing it, but will contribute to the (long-overdue!) advancement of healthcare research for biologically female people.

Elizabeth discusses what the medical research gender gap is, why it's a problem, and how we can help close it. She also tells us more about why her company is first tackling the problem of "trial and error" birth control selection that has plagued the reproductive years of so many of us, how they're using actual research and data to do this, and where this technology may go next. Lastly, Elizabeth explains why Adyn won’t call itself a “women’s health company.”
