Semen culture for prostatitis is less accurate because it can be interfered with by seminal vesiculitis and orchitis, and it is generally recommended that prostate fluid be taken for culture. Although most of the semen is made up of prostate fluid, a bacterial culture of semen cannot replace a bacterial culture of prostate fluid, because it is impossible to determine whether prostatitis or seminal vesiculitis or orchitis is the cause of a positive semen culture result. Only when there is a blockage of the prostate ducts can you consider taking a semen culture under sterile conditions for reference, but the results are not as accurate as those of a prostate fluid culture. Prostatitis is usually treated with a bacterial culture plus a drug sensitivity test to confirm the diagnosis of prostatitis infection and to select the appropriate antibiotic for treatment based on the results of the drug sensitivity test. Before taking the prostate fluid, you need to carry out urine routine and urine culture to exclude urinary tract infection. If you have prostatitis, please consult the doctor promptly for treatment.
