What no one tells you about testosterone replacement therapy | Science Quickly Podcast

Testosterone replacement therapy (TRT) is exploding in popularity among men. TRT has been touted online as a cure-all for everything from low energy to poor mood and even as a way to increase masculinity itself. But how much of the buzz is backed by science? Host Rachel Feltman talks with journalist Stephanie Pappas about the realities behind the trend. They explore who truly benefits from TRT, the overlooked risks—including fertility loss—and the rise of private clinics offering testosterone.
