Any androgen is bound by lots of different steroid-binding proteins. But the ones that are most pertinent are called SHBG, or sex hormone-binding globulin. And that binds the androgenic steroid, for example, DHT or dihydrotestosterone. It's associated with prostate enlargement, it's associated with male pattern baldness. It binds that the most strongly, and then it binds testosterone next most strongly
