Intersex people have always existed. How they first started to find each other, build community and forge a movement against medical erasure is a story that’s mostly gone untold.

A new book aims to change that. “Hermaphrodite Logic: A History of Intersex Liberation” by writer, comedian and historian Juliana Gleeson was released in June by Verso Books. It’s a roughly 230-page dive into the very brief history of organizing for intersex rights from the 1990s to present day.
