The most common symptoms of mumps include fever, headache, muscle aches, tiredness, and loss of appetite followed by onset of parotitis (swollen and tender salivary glands under the ears -- on one or both sides).
Mumps can lead to hearing loss and aseptic meningitis (an infection of the covering of the brain and spinal cord) in about 10% of cases. Painful, swollen testicles occur in 20% to 30% of males who have reached puberty (orchitis) -- but rarely does this lead to fertility problems. About 30% of women who have reached puberty can have painful swollen breasts (mastitis) from mumps and, in a very few cases, inflammation of the ovaries.
Infertility is when you cannot get pregnant after having unprotected, regular sex for six months to one year, depending on your age.
The main symptom of infertility is not getting pregnant. You may not have or notice any other symptoms.
Symptoms can also depend on what is causing the infertility. Many health conditions can make it hard to get pregnant. Sometimes no cause is found.
