The first stage daily dosage portion is an effective amount of natural estrogen, the second stage daily dosage portion is an effective amount of a combination of natural estrogen and natural or synthetic gestogen, the third stage daily dosage portion is another effective amount of natural estrogen and an additional stage daily dosage portion consists of a placebo. The first group of the second stage consists of 3 to 5 daily dosage portions and the second group, 13 to 17 daily dosage portions. More of the gestogen is included in the effective amount in the second group of the second stage than in the first group. The effective amount of the natural estrogen is constant in both the first and third stages, but smaller in the third stage than in the first stage.
