Urethritis historical perspective

The first known case of urethritis was described by Albert Neisser, a German doctor, in 1879. In 1904, Ludwig Waelsch described mild non-gonococcal urethritis (NGU). In the 1930s and later, Philip Thygeson and others in the United States confirmed the vertical transmission of nongonococcal urethritis (NGU).
