The aim of this study was to evaluate whether age of onset of multiple sclerosis is related to use of combined oral contraceptives and/or timing of childbirth. The results showed that use of combined oral contraceptives and childbirth before the first multiple sclerosis symptom was correlated to a higher mean age at the onset of the disease.
