Trying to take this seriously... Is there some psychological explanation for elevated T, especially when the subject is aware their testes are about to be crushed by an air bladder? That is, could fear and courage cause a rise in testosterone?
That seems pretty delayed for a psychological effect? Although, I'm not a biologist, so no idea how long the on-demand testosterone synthesis pathway is.
> 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%, wi…
So I’m slightly confused, did you need the exercise to increase the testosterone or not?
So putting a 2 PSI spacesuit on the astronauts is about half as effective as lifting waits at increasing testosterone levels.
Earlier quoted context omitted.

> 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.
Should've waited till April 1st to publish this.
I was caught once by that in Spain: Their April Fools is on December 27th, and is called Holy Innocent’s Day. https://en.wikipedia.org/wiki/April_Fools%27_Day
> Mechanical compression alone did not explain the rise in serum testosterone, although it may have a contributory role.
