What No One Tells You about Testosterone Replacement Therapy

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. This episode was
made possible by the support of Yakult and produced independently
by Scientific American’s board of editors. Recommended reading:
