<p>A portable fertility tester for identifying days during the menstrual cycle when a woman is most likely to conceive has a circular disc, with transparent regions indexed to each of the days of the cycle, rotatably mounted within a housing and cover. The housing and cover form a window for exposing a transparent region on the disc for depositing a saliva specimen. An ocular is provided with a magnifying lens for examining the appearance of the saliva which is indicative of fertility, and a light emitting diode is provided for backlighting the specimen during examination. The cover may be removed to allow replacement of the disc for each menstrual cycle.</p> |
