AN OCULAR (45) IS PROVIDED WITH A MAGNIFYING LENS (31) FOR EXAMINING THE APPEARANCE OF THE SALIVA WHICH IS INDICATIVE OF FERTILITY, AND A LIGHT EMITTING DIODE (33) IS PROVIDED FOR BACKLIGHTING THE SPECIMEN DURING EXAMINATION. THE COVER (4) MAY BE REMOVED TO ALLOW REPLACEMENT OF THE DISC (19) FOR EACH MENSTRUAL CYCLE.
