Fietsbob is right: tilting the nose of the saddle down can create the problem of tending to slide forward on the saddle. Then you will expend energy on trying to keep yourself on the saddle. One or two degrees of downward tilt is often tolerated if the saddle is the right shape, but more can create issues.

Is your discomfort/pain only testicular?

Also, pain can sometimes be "referred". That is to say, you experience it in one place but it is caused elsewhere. If this is the case, a saddle with a cut-out may help.
