Pathways of entry of pathogenic organisms into the prostate may include hematogenous dissemination from distant foci of infection, extension via lymphatics, transmission via infected urine from kidneys, or retrograde entry via the urethra. The last route of entry seems to account for most episodes of prostatitis. Indirect evidence from studies of patients with prostatitis points to retrograde entry of bacteria via the urethra following oral, anal, or genital intercourse or masturbatory practices as a major means of induction of prostatitis. Evidence is based upon similarity of organisms recovered from various orifices to those in the prostate, apparent low incidence of prostatitis in asexual males, and appearance in the prostate of bacteria which reside in the distal urethra. Definitive studies are necessary to prove this hypothesis; emphasis must be placed on correct diagnosis of prostatitis.
从远处感染灶经血行播散、经淋巴管蔓延、经肾脏感染尿液传播或经尿道逆行进入。最后一种进入途径似乎是大多数前列腺炎病例的病因。对前列腺炎患者的研究间接证据表明，细菌经口交、肛交或性交或手淫后经尿道逆行进入是诱发前列腺炎的主要方式。证据基于从各个孔口分离出的微生物与前列腺中微生物的相似性、无性男性中前列腺炎的明显低发病率以及远端尿道中细菌在前列腺中的出现。需要进行确定性研究来证实这一假设；必须强调前列腺炎的正确诊断。
