Treatment of menorrhagia with intrauterine release of progesterone.

In 12 women with menorrhagia (greater than or equal to 80 ml per menstrual period) a progesterone-releasing device (Progestasert) was inserted. The women were followed by repeated measurements of the blood loss for 12 periods. The menstrual blood loss was significantly reduced after 1 month but the duration of bleeding was somewhat prolonged. Twelve months after insertion the menstrual blood loss amounted to 35% of the blood loss before the insertion. The Progestasert is a valuable treatment for menorrhagia.
