It occurred to me that the  Aggression  promoted by   Testosterone  requires at least some Behavioral Disinhibition  of the Tonic Inhibition  ascribed to GABA/Glycine Inhibition .  To look into this further, I've started this new page .

Clinical data on a combination of gamma-aminobutyric acid and an androgen in psycho-neuro-endocrine disorders   
Note:  This paper is in Portuguese, and there is no Abstract available.  What's more, although PubMed lists 140 "Similar articles", most of them are either not in English, or have no Abstract or both.  However, the titles explicit mention of both GABA and androgen make it of major interest to me, so I'm going to go ahead and look at the Similar articles to see if I can find anything helpful. 
Note:  I've reordered the references from the default "Sort by Link" to "Sort by Publication Date" which allows me to deal with them in chronological order.

Cerebrospinal fluid GABA levels in various neurological and psychiatric diseases.   
Cerebrospinal fluid gamma-aminobutyric acid (CSF-GABA) was analysed by radioreceptor assay in 16 normal controls and 84 patients with various neurological and psychiatric diseases. In patients with spinocerebellar degeneration, neuro-Behçet's syndrome and Parkinson's disease, CSF-GABA levels were decreased. On the other hand, increased CSF-GABA levels were detected in patients with meningitis."

No Abstract, but I skimmed the full article.  No mention of testosterone. 

I'm surprised I found so little.  I had expected much more.

    My overall commentary on all the references identified by this search: 
Although these references discuss "reward", none of them acknowledges that this reward is a manifestation of reduced  GABA/Glycine Inhibition  or  Tonic Inhibition  or an increase in  Behavioral Disinhibition .

Differential effects of estrogen and androgen on locomotor activity induced in castrated male rats by amphetamine, a novel environment, or apomorph...   
It is suggested that the selective, facilitatory effect of E2 on drug- and novelty-induced locomotor activity resulted from increased postsynaptic receptor activation at dopaminergic synapses in the nucleus accumbens septi."

Rewarding affective properties of intra-nucleus accumbens injections of testosterone.  
The findings indicate that intra-accumbens injections of testosterone are sufficient to produce reward."   
    My comment
No mention that the "reward" is physiologically a reduction of  GABA/Glycine Inhibition 
or  Tonic Inhibition  or an increase in  Behavioral Disinhibition .

These data are consistent with the hypothesis that the hedonic effects of T may be due to actions of its metabolites in the NA."
