This article describes the prevalence of hysterectomy, women's own opinions of it, and socioeconomic characteristics of hysterectomized women compared to non-hysterectomized ones. The questionnaire was sent in spring 1989 to 2000 45 to 64-year-old Finnish women picked randomly from the Population Census. After two reminders, 1713 (86%) had responded. One fifth of the women had had a hysterectomy and 5% had also had both ovaries removed. Among the highest educated there were less hysterectomized women than among the less educated. The largest differences in the prevalence of hysterectomy were between counties, not between socioeconomic groups. Fourty-one percent of the hysterectomized women had themselves wished hysterectomy, 25% did not have any specific opinion about the operation. Results raise further questions about clinical decision making and regional variation of hysterectomy.
