How to prevent penile tuberculosis?

Patient's question:

No illness, just want to consult about penile tuberculosis

Doctor's answer:

(1) Direct contact: Such as during sexual intercourse, the penis comes into contact with a tuberculous lesion in the vagina or cervix. This primarily occurs on the head of the penis and near the external urethral orifice.
(2) Most cases are secondary to pulmonary tuberculosis, spreading to the penis cavernosum through the bloodstream.
(3) Severe urethral tuberculosis may rupture and directly spread to the penis, forming fistulas.
