Guys, if you look at Melcangi study and Wuf's blood tests and CSF values. You will clearly see, that DHT is zero in CSF. It is very low and testosterone is high in CSF
Testosterone is not being converted into DHT in the brain. It is very clear. And since testosterone is already high there body wants to bind stuff with SHBG
You can see it here, that SHBG controls the entrace of testosterone into CSF The effects of sex hormone binding globulin (SHBG) on testosterone transport into the cerebrospinal fluid. - PubMed - NCBI
So this tells you that 5AR is not working in the brain. Possible since the body does not want to convert testosterone into DHT.
Now if you look further into that study. and Wuf's tests. You will see that progesterone and pregnenolone are also super low in CSF.
Why? The only way how they could be low is if they are bound by CBG( transcortin ) in blood. and transcortin binds cortisol also mainly
Now follow me. if progesterone is low in CSF , then how would testosterone convert into DHT in the brain. 5AR reductase will be prohibited, since 5AR will convert progesterone further down into its metabolites, but it is already low.
This is your fork.
And I think this might have happened, since androgen deprivation caused GR overexpression, and AR overexpression.
And then when you quit the drug, both CBG( transortin ) and SHBG go up . trying not to let DHT and Cortisol into the brain. and by doing this. They bind other hormones also, like estro and progesterone.
And binding of progesterone stops even remote possibility of downregulation of AR since 5AR will never go up.
