Testicular swelling
Mumps may result in testicular swelling and tenderness. Around half postpuberal males who get infected with mumps get a condition known as orchitis, where they complain of unilateral or bilateral swelling of the testes. It is not common to reach sterility, but it is a possibility. A much lower proportion of females experience swelling of the ovaries, known as oophoritis, which basically causes abdominal pain, and should be differentiated with pancreatitis.
