Tryptophan administration lowers T levels

I have a few questions as the study is a bit over my head:

1. Is it reasonable to assume that the same effects could be observed in humans?
2. Any way to counteract the T lowering effects described in the study?
3. Is a low dose of melatonin (1mg) going to have similar effects?

I do like my tryptophan but I don't want sth to decreasing my T levels as I am already borderline low now. I wonder if tryptophan is to blame..
 
"Human chorionic gonadotropin (HCG) administration in L-tryptophan treated rats for 21 days increased the plasma testosterone level in spite of increased brain 5-HT level."

Just grab you some hcg :)

Judging solely from the abstract, it appears to be saying that higher levels of 5-HT in the brain correlates with lower testosterone levels. But is it only when those levels are elevated due to trytophan dosing? Or are high 5-HT levels always indicative of lower T? Probably not that cut and dried. Reminds me of the vitamin D study where subjects with higher D levels had higher T.
 
ssri's increase synaptic levels of serotonin and have also been associated with lower testosterone levels

how much tryptophan were they giving these animals?
