PROBLEM TO BE SOLVED: To predict and display the next and succeeding menstruation dates or the next and succeeding ovulation dates.SOLUTION: A reference body temperature is calculated from the measured history of a basal body temperature, whether the date is a high temperature phase or a low temperature phase is judged for each measurement of the basal body temperature, the next menstruation date is estimated corresponding to the phase, and the next ovulation date is estimated and preserved. Thereafter, the preserved next menstruation date or next ovulation date is displayed corresponding to an operation by an operator (S904, S917). Further, by adding an average menstruation cycle to the next menstruation date or the next ovulation date corresponding to the operation of left and right buttons, the menstruation dates after the next one and the ovulation dates after the next one are predicted and displayed (S908).COPYRIGHT: (C)2009,JPO&INPIT【課題】次回以降の生理日または次回以降の排卵日を予測し表示する。【解決手段】基礎体温の測定履歴から、基準体温を算出して基礎体温の測定ごとにその日が高温相か低温相かを判定し、相に応じて次回生理日を推定し、また次回排卵日を推定して保存する。その後、操作者の操作に応じて、保存した次回生理日又は次回排卵日を表示する(S904,S917)。さらに、左右ボタンの操作に応じて、平均月経周期を次回生理日又は次回排卵日に加算することで、次々回以降の生理日又は次々回以降の排卵日を予測して表示する(S908)。【選択図】図9A
