T Levels: Is This Low?

I just got the results of my Testosterone levels and it is about 3.2 ng/mL i`m 25 years old, my weight is 195 Pounds, and my fat % should be around 25% or more, is this low? how can i improve it naturally

Regards

That’s only 320 ng/dL, which is very low. I would talk to an endocrinologist.
