Funding the future

of women’s health

Building on what we started last year, we’re continuing our mission to close the gender health gap.

Women make up 51% of the population — yet remain underrepresented in medical research

2.5%

of global medical research funding is estimated to go to women’s health.

90%

of women experience period pain — yet erectile dysfunction, affecting only 19% of men, is studied five times more.

1993

when women finally made it into clinical trials. Before then, medicine assumed we were just small version of men.
