Definition / general
- Testicular infections rare in infected children (prepubertal) but occur in 15 - 40% of postpubertal men one week after parotiditis
- Usually unilateral (bilateral in 15 - 30%); epididymitis is also common (85%) and often precedes orchitis
- 1/3 of infected postpubertal men develop testicular atrophy, 2 - 10% become infertile
- Incidence increasing, due to reduced use of vaccine (BJU Int 2010;105:1060)
