In this special edition of the Here & Now podcast, Jeremy Hobson talks with Patrick Burleigh, who has a rare genetic mutation that triggers testosterone production in boys as young as 2 years old. It causes what doctors call precocious puberty, or testotoxicosis. Burleigh wrote about his experience growing up with the mutation for New York magazine, and he tells us about what his life was like when he was a kid — and how he and his wife assessed the possibility that their male children might also have the mutation.
