We need a study for either blood or semen.

Also.. we want all animals to be living in the wild.

How does that gonna affect on results of Testosterone levels?

The concentration of testosterone in blood plasma was greater than, and positively correlated with (r = .75, P less than .01), the concentration of testosterone in the ejaculate

Testosterone concentration in semen from the 70 men investigated was 69 2 4 ngllOO ml, and in venous blood 487 2 20 ng/100 ml. However, in blood, one-third ofthis steroid was bound to testosterone binding globulin (TeBG), while no TeBG bound fraction of testosterone was found in seminal fluid.

"Also, I personally think tigers have more testosterone levels of all bigcats. Due to their great territorial aggression and behaviour..."
