If your levels are that low, assuming you're saying 11 ng/dl and 92 ng/dl, it's unlikely any natural method is going to increase your levels significantly enough to bring them out of a low level state as those are extremely low numbers. I'm not saying it's impossible, but it is unlikely.

How old are you?
Have you ever used opiates/pain pills for extended periods of time or are you currently?
Are you currently or have you used anti-depressants for long periods of time?
Do you have any testicular damage or head trauma in your history?
Have you ever or are you currently using anabolic steroids?
Do you have any history or recreational drug use?
