There are still loads of men around that have decreased fertility or even infertilitt due to mumps. Without ever asking around I know at least three men that had fertility problems, probably due to severe orchitis after mumps. In Sweden they included mumps in the vaccination programme 1975ish, which probably means the USA got it sometime during the 60s. That means you have probably all met someone that had testicle or pancreas inflammation due to mumps. Both of them very very painful.
