(surgery for torsion) has been done there should be no issue to getting back to full steam within a month. The surgery per se is not major and recovery is quick. You should of course take all routine precautions like proper support and protection for the testicles.
Also a little more detail about the surgery would be useful. Was the testicle salvaged? Was the opposite testicle also fixed to prevent a future torsion on that side?
Answers to these questions will help much better in giving a qualified opinion to your questions.
