I had a trauma on my testicle and i have some symptoms of infertility, if somehow can i treat this?

What are the symptoms of infertility you talk about? Besides radiation exposure to the genital organ, trauma rarely affects both testicles at the same time.

What kind of trauma, one side or both? Infertility is unable to impregnate a female after at least !8 months of trying. If this is your problem you will need two consecutive semen exams few weeks apart and a Urologic evaluation-
