Low testosterone or flatline?

how do I know if my problem is low testosterone?

Do you go to the gym? Are your muscles getting pumped? Are you growing facial hair, leg hair, etc?

If so, this reduces the chance that it's Testosterone.

sorry but I use google translator.
for a few weeks after my start of reboot, I did not get any morning wood, one day I decide to start doing gym and the next morning I get a morning wood, I continue the gym for a week and in these mornings I get every day morning woods.

I finish the gym and the following days I do not get morning woods.
then I start again gym and a morning wood immediately reappears.
a testosterone boost can help to have morning woods even if i'm flatline?
can it be the sign that my reboot is ending?
through research on the internet I exclude any disease that can lead to a hormonal lack.
also during my reboot I had wet dreams porn and I could get erections thinking of porn (but I could not get erections thinking of a girl normally).
so I know I have a flatline but I can not explain the story of the mornings woods

Not sure if it can help but maybe try and read this? Basically it's a walk through with the potential symptoms you can experience during your reboot.
