International ClassG02B 021/00AbstractA compact, self-contained, easy-to-use and readily portable apparatus which can be carried in a woman's purse or pocket for determining the period of maximum fertility. The apparatus includes a hollow housing that sealably contains a small magnifying system, a saliva specimen slide and an internal switch operated illuminating system for illuminating the saliva slide. The small magnifying system is used to closely view patters formed on the specimen slide by the saliva after it has dried and crystallized on the slide. The patterns are then compared with standard comparison patterns to determine the woman's present ability to conceive.Other References
