I had a penis yeast infection after starting a treatment few days later has a pain in right testicle which resulted in semen ejaculation during bowel movement. So after experiencing on and off pain for 2-3 times during this two weeks, visited urologist today who advised to get urine analysis and ultrasound scrotrum with color dopler but both tests came negative with no signs of infection. After that doctor said it is prostatitis and sometimes this bacterial infection doesn't get detected in this test. And given 3 weeks antibiotics treatment. Is this diagnosis correct?
