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 circular base member having indicia representing the calendar dates for the days of a given month disposed around the periphery thereof, and an index member rotatably secured to the base member and having an index and an indicator disposed thereon and configured so that when the index is aligned with the calendar date corresponding to the day of the onset of the menses, the indicator is positioned to indicate the calendar dates for a seven day interval starting ten days after the indexed date thereby indicating the time interval during which ovulation should occur and thus the days on which the probability of conception are the greatest.
