Associations Between Earlier Menarche and Fibroid Severity in Individuals Seeking Hysterectomy

Early menarche is associated with uterine fibroid risk, but the association between menarcheal timing and fibroid severity remains to be explored. Given the hormonal dependence of fibroids, earlier menarche may increase physical burden (e.g., number of fibroids) and/or symptoms (e.g., heavy menstrual bleeding), though the two are not always correlated. We hypothesized that individuals with earlier menarche are more likely to have severe fibroids.
