How Many Genders Are There, Really?

A question that seems to ask for a number, but conceals three different answers.

About

Two boxes on a form seem sufficient — until you try to fit the whole range of human experience inside them. What exactly is biological sex? What do intersex, transgender, and non-binary mean? And why is sexual orientation not the same thing as gender identity?

This audiobook untangles the words that have become a battlefield, without slogans or evasions. From embryonic development and same-sex behaviour in nature to the psychiatry that once called homosexuality an illness, legal transition, elite sport, and same-sex marriage in Greece.

It does not promise an easy answer. It promises something more useful: to know which question you are asking before you start to disagree.
