Abstract

A human reproduction indexing device for indicating the calendar dates for days of a menstrual cycle on which the probability of conception is the greatest includes a generally rectangular member having indicia representing the calendar dates for the days of given months positioned in three separate columns on the member and indicator-index columns aligned and positioned adjacent each of the separate columns on the member. When the calendar date corresponding to the day of the onset of the menses is known, the indicator-index columns indicate the calendar dates for an eight day interval starting ten days after the indexed date to provide the time interval during which ovulation should occur and thus the days on which the probability of conception are maximized.

Claims

1. An indexing device for maximizing the probability of conception comprises a member having indicia representing the calendar dates for the days of the months positioned in three separate calendar columns on the member and indicator-index columns aligned with and positioned adjacent each of said calendar columns, said indicator-index columns indicating the calendar dates for an eight day cycle starting ten days after the predetermined index date to provide the time interval during which the probability of conception is maximized.

2. An indexing device in accordance with claim 1 further including a plurality of recording space means positioned on said indexing device for recording the predetermined index date.

3. An indexing device in accordance with claim 1 wherein said device is composed of plastic.
