The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
And DHT is crucial so 5alphaR (the enzyme that converts testosterone to DHT) is a key element.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.

So this ends. There's testosterone that's made. And that testosterone gets converted by this enzyme 5-alpha-reductase in a little structure called the tubercle. That tubercle will eventually become the penis. So you say, "Okay, straight forward." This testosterone is converted to dihydrotestosterone. And then if there's dihydrotestosterone it controls penis growth.
