About Hormonal

Hormones affect everyone and everything: from skin to stress to sports.

But for most of us, they're still a mystery. Even the way we talk about hormones makes no sense. ("She's hormonal.")

So let's clear some things up. Each week, Rhea Ramjohn is asking scientists, doctors, and experts to break it all down for us.

A new podcast from Clue. Season 1 launches this fall with eight weekly episodes.

Trailer Transcript

Randi Epstein [00:00:00 - 00:00:09]: When we talk about hormones, we're not talking like a cup of sugar amount. We're talking like one grain of salt thrown into the ocean, and it has a huge impact.

Rhea Ramjohn: Introducing Hormonal: A podcast about how hormones shape our world. Brought to you by Clue. 

Each week, I, your host Rhea Ramjohn, will have experts on the show to break it all down for us. And this season on Hormonal, we’ll focus on just that: hormones. 

Martie Haselton [00:00:29 - 00:00:36]: The idea that many people have, that being hormonal, means that we've like, gone a little crazy, is I think backwards.

Rhea Ramjohn: We’ll talk to historians on the evolution of endocrinology.

Randi Epstein [00:00:42 - 00:00:46]: The gland business was huge. You know you have two testes, why not three? 

Katrina Karkazis [00:00:47 - 00:00:58]: So as early as the 1930s, 1940s, there were these ridiculous things called certificates of femininity, and you had to be issued one in order to compete. 

Rhea Ramjohn: And hear from writers, who examine and challenge long established medical and scientific ideas. 

Martie Haselton [00:01:05 - 00:01:11]: If we rethink it in that way, then this is no longer premenstrual syndrome. It's premenstrual strategy. 

Katrina Karkazis [00:01:12 - 00:01:23] What they do is a gynecological exam to look at the size of the clitoris, and in many ways this must sound utterly ridiculous, like, you know, there's no such thing as clitoral weightlifting.

Rhea Ramjohn: And, scientists on the ground about how their research is fueling a new understanding of how hormones nudge and drive us. 

Virginia J. Vitzthum [00:01:36 - 00:01:46]: So this required that I collect over 10,000 samples of saliva, over the course of two years, and God knows how many gallons of pee. [LAUGHS]

Rhea Ramjohn: Hormonal is brought to you by Clue, the period tracking app and menstrual encyclopedia.

So join me, as we talk about the research, the ethics, and the cultural myths, around hormones.
