What are the causes of seminal vesiculitis?

The main causes of seminal vesiculitis are as follows: 1. Bacterial infection: including retrograde infection via the vas deferens, such as bacteria from epididymitis invading the seminal vesicles through the vas deferens, as well as specific bacterial infections caused by organisms like Trichomonas, Mycobacterium tuberculosis, and Neisseria gonorrhoeae. 2. Lymphatic infection: inflammation of the urogenital tract or intestines may spread to the seminal vesicles via the lymphatic system. 3. Hematogenous infection: pathogens from infection sites elsewhere in the body reach the seminal vesicles through the bloodstream. 4. Unhealthy lifestyle habits: irregular作息 (daily routines), poor personal hygiene, and excessive sexual activity may reduce immune function, thereby increasing susceptibility to pathogenic infections.
