E. coli in semen. To know is it curable?

From December 2024, I had symptoms such as pain and burning after urination, burning after ejaculation, difficulty starting urine and intact burning randomly if I sit or stand for long. The burning feels like it affects my thighs as well. Went to multiple urologist. None helped until i went to a new one and got diagnosed with E. coli in semen. This was already 6 months now. I got prescribed IV antibiotics for 2 weeks twice daily and after a month now, there is no E. coli left in my semen culture. But still completing the entire dose of antibiotics, I am half relieved. The symptoms comes and goes. The intensity of these symptoms after the antibiotics are a little less but the pattern is same. Infact the burning which starts remains for hours causing discomfort which is sometimes more, sometimes less. The urologist prescribed me another 2 set of antibiotics namely bactrim ds and doxt sl 100 for 2 weeks along with a nerve medication and alpha blocker. I want to know is it curable?
