"Funiculitis refers to inflammation of the spermatic cord (in TA it is called funiculus spermaticus 9). In general, cases that have historically been called funiculitis are really an inflammation of just the ductus deferens, i.e. vasitis. Therefore it has been said that the latter term is preferable. Occasionally the inflammation may spread such that the entire spermatic cord is involved forming a true funiculitis 2,8."
"The causative organism may be sexually transmitted infections such as Neisseria gonorrhoea and Chlamydia spp., or a uropathogen such as Escherichia coli. Tuberculous vasitis has been described. Infections of the ductus deferens may be associated with epididymo-orchitis and prostatitis or may be primary. It may be associated with urogenital surgery such as vasectomy, prostatectomy and hernia repairs."
