I remember looking at this a while back out of sheer interest as a cyclist (this is WAY outside my field of expertise) and it would seem that hard training/riding actually decreases testosterone levels in some cases. One study I read actually measured testosterone levels, etc. of a pro team in the Vuelta A Espana, and showed that a grand tour really kinda makes a mess of a person endocrinologically, which includes a drop in testosterone.
What happens acutely, though, with hard training or exercise, seems to be the opposite, but there are much smarter people than me out there when it comes to this stuff.
