This episode reruns a classic 2002 broadcast about testosterone, exploring how much the hormone actually determines human behavior, desire, and personality. Prompted by news of a government mandate testing military personnel's testosterone levels, host Ira Glass and producer Alex Blumberg revisit stories examining the chemical's psychological impacts. These include an interview with a trans man receiving massive testosterone injections, an ill-fated office experiment where the entire radio staff tested their hormone levels and predicted rankings, an account from a man who temporarily lost all testosterone due to medical issues, and a mother observing her teenage son navigating puberty.
Throughout the episode, the contributors and guests grapple with the tension between biological reductionism and personal identity. The staff's saliva tests reveal surprising results—such as a gay male contributor registering twice the testosterone of anyone else—while highlighting the awkwardness and anxieties of trying to quantify personality through body chemistry. Ultimately, the reporting portrays testosterone not as a simple switch for aggression or masculinity, but as a complex mediator of desire that both complicates and illuminates human self-perception.

(00:00:00) Prologue: Host Ira Glass talks with producer Alex Blumberg, who explains that he wanted to do this show because of his conflicted relationship with his own testosterone.
