Urethritis is defined as infection-induced inflammation of the urethra typically caused by
a sexually transmitted disease (STD). Urethritis is normally categorized into one of
two forms, based on etiology: gonococcal urethritis (GU) (ie, due to infections with Neisseria gonorrhoeae) and non-gonococcal urethritis (NGU). It is already well known
that mycoplasmas, especially M. genitalium and Ureaplasmas are almost as
common etiological factor of this ailment, as Chlamydia trachomatis.
Potential complications of urethritis in males include prostatitis, acute epididymitis,
infertility due to abnormal semen, and reactive arthritis.
