Primary dysmenorrhea peaks in late adolescence and the early 20s. [36] The incidence falls with increasing age and with increasing parity. In many studies, [10, 37, 38] though not all, [4] the reported prevalence and severity of dysmenorrhea in parous women are substantially lower. An epidemiologic study found no significant differences in prevalence and severity of dysmenorrhea between nulligravid women and those in whom pregnancy had been terminated by either spontaneous or induced abortion.
