This is a great listen on the biology of sex.

"Many of us were taught biological sex is a question of female or male, XX or XY ... but it's far more complicated. This hour, TED speakers explore what determines our sex." https://radiopublic.com/TEDRadioHour/s1!f02c6

I listened to this episode of Radiolab in 2019 & it does a super deep dive into the science of sex development that we did not learn in school. This is the episode referenced in the Ted Radio Hour podcast episode above. http://www.wnycstudios.org/story/gonads-xy/

And since hyperfocus on topics that interest me is a hallmark of my #ADHD, I had to learn more. This thread below is hella long but hella good &
it has a whole bunch of other doctors arguing in this doctor's mentions about the concept of "biological sex"
