Answer

Mumps orchitis follows the development of parotitis by 4-7 days. Obtain a sexual history, when appropriate.

The clinical manifestations of mumps orchitis in 62 postpubertal vaccinated patients included mean incubation period 5.39 days (range, 0 to 23 days), a febrile duration of 1.8 days (range, 0.5 to 3 days), and a mean duration of orchitis of 4.96 days (range, 0 to 17 days). Sonography revealed unilateral orchitis in 58 patients (93.6%) and bilateral orchitis in 6 (6.4%). The mean age of the 62 patients was 17.56 years (range, 15 to 29 years). [9]
