Mumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face. However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy. Some effects include oligospermia (low sperm count), azoospermia (no sperm in semen), and asthenospermia (reduced sperm movement).
