I feel like people underestimate how incredibly important a healthy level of testo is, even for women. Science has become so simplistic with their whole "uhm uh, yeah it's dat sex hormone 'n shiet". It regulates so many things besides the libido, especially psychologically. Your level of motivation, affect regulation, etc. all depend on normal testosterone concentrations. If it's too low, you'll suffer from symptoms that can mimic depression, like avolition, trouble concentrating, mood swings, anxiety, etc.
This is why so many who use opioids long-term, become passive, apathetic individuals who lack any drive to do anything and become irritable so easily. I feel much better since I started to control my habit (I occasionally slip, but hey, at least I don't use daily anymore).
