> Serum testosterone levels are increased in athletes after short-term exercise. To investigate whether mechanical compression could contribute to this increase, we subjected 14 male volunteers to mechanical testicular compression via a pneumatic cuff. The serum testosterone levels were sampled at time intervals before, during and after compression. There was a rise in mean serum testosterone levels of 16.7-18.2%, with a maximal increase at 1.5 min after compression was released. Mechanical compression alone did not explain the rise in serum testosterone, although it may have a contributory role.

So I’m slightly confused, did you need the exercise to increase the testosterone or not?

> Jensen [3] showed a rise in mean testosterone (s-T) concentration of 27 % and 37 % during strength and endurance training, respectively.

So putting a 2 PSI spacesuit on the astronauts is about half as effective as lifting waits at increasing testosterone levels.

That’s so interesting endurance training increased testosterone more. That’s it, I’m going for a run :-)
