I would venture to say that testosterone is not the "problem" but lack of doing something constructive with testosterone. There are healthy and rewarding ways to use testosterone, and it provides drive and confidence. I would hate to see us vilify testosterone in general as it's not "bad."
I'm not an expert by any means, but have a lifetime of living with men.
I've seen the the men in my life thrive when they can use their physicality and drive, whether it is sports, academics, business, military, fitness, leadership, protecting, taking on challenges, career, hobbies, etc.
Fwiw.
