Pubertal and postpubertal males who have not received mumps vaccination are more susceptible to the virus and have a high risk of mumps orchitis. [11]

Mumps outbreaks have resulted in substantial increases in cases of orchitis. The mumps outbreak in England in 2004-2005 resulted in an increase in orchitis cases of up to 2 to 2.5 times in some populations (those born in the 1970s and 1980s). In comparison, during the years of low mumps incidence following introduction of the MMR vaccine, mumps-related orchitis was significantly reduced in those who did come down with the disease. [4, 27]

In the Czech Republic, 2-dose vaccinations against mumps showed a significant preventive effect agains the mumps complications of orchitis, meningitis, and encephalitis. However, complications increased with the time interval after vaccination. [28]
