As a male surgeon, I am mortified that the profession allows my female colleagues to be treated like second-class citizens. I have watched women surgeons get bullied, harassed and discriminated against by their male counterparts. I have seen a countless number of their careers crumble in front of my eyes. I have seen their tears. I have seen them go into a deep hole of depression and never come back. And I'm embarrassed to say that for a long time, I did nothing about it.
