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.
