Testicular Trauma. Enough testosterone.

I got kicked in the testicles on 16th nov 2016, i consulted a doctor on that day he gave me some antibiotics, pain relievers an injection and some infection medicines. I got an ultrasound 5 days after the injury, it was diagnosed to be a testicular trauma. I felt good after a 40 days i was off medication, but i soon started feeling like my left testicle(the one i got hurt on) started shrinking. And i started to urinate a lot by 7 th of jan 2017 and my body started itching i was given UTI ( urinary track infection) medicines by the doctor and the urine test came out normal. I also told him about the atrophy of my left testicle and that my right one was getting bigger. He thought i was suffering from PTSD and gave me some medicines which i found out to be GABA initiators. My right testicles not hangs lower and the left one feels pretty small. I want to know if the atrophy could be prevented through surgery and if my testicles are able to produce enough testosterone.
