Well for people with delayed LTCs there is a greater chance of this stuff. Estrogen isnt a problem until you try treating the T so its not a direct issue.
Testosterone isn't the biggest problem as much as the pregnenolone/progesterone/cortisol stuff. You can afford lower T if your preg/prog/cortisol is better. DHEA-S also plays into this somewhere. In the beginning of my LTC when I was numbed/anxious and in a terrible state I had very low pregnenolone+progesterone. I also had low cortisol.
However, I responded to the ACTH stim test and the endo was like ok no problem but the endo was wrong--the ACTH stim is not a good representation of the real biology. The best test is if your cortisol isn't high under physical/mental stress it shows adrenal insufficiency.
However, it just so happens that the treatments for Testosterone that are not directly replacing T such as HCG or SERMs can help you regenerate preg/prog/cortisol.
Here is a good paper explaining "bioenergetic stress" from MDMA. Bioenergetic stress is essentially "adrenal fatigue" but is a medically accepted term. Adrenal fatigue is real but has just been totally unaccepted cause too many quacks out there have misdefined it as an adrenal problem when it is actually a brain thing.

When you push your body too hard it causes this. Doesnt happen in everybody cause their bodies can cope better due to other factors unrelated to mdma such as vitamin/mineral status. If I recall correctly, you also didnt experience a direct LTC and it was delayed and happened cause you suddenly couldnt handle school
That completely falls into this "bioenergetic stress" model.
For others it may have started after a drinking sesh a few weeks later, or an illness. Or even randomly--the random cases aren't "random" but seem that way cause the "stress" is something physical that is unidentified.
And then the symptoms cause mental stress which further pushes you to a total breakdown.
