Dipartimento di Scienze Biochimiche, Università di Firenze. We found that the fern leaf crystallisation of human saliva is a non-specific phenomenon, independent on the action of estrogenic hormones. Salivary ferning can be obtained in practice during the whole menstrual cycle and occurs in the saliva of postclimateric, pregnant and prepuberal women. Even the saliva of male subjects gives invariably the ferning reaction. In conclusion, salivary ferning does not seem a reliable method to establish a woman's fertile period.

Abstract:
The present study aims at determining the scientific reliability of salivary ferning pattern as a method to detect ovulation in normal women. The saliva was collected from unmarried women in the age group of 20-30 years. The saliva, collected at three different phases (i.e., preovulatory (6th-12th day), ovulatory (13th-14th day) and postovulatory (15th-28th day)), was smeared in the glass slide and observed under microscope.
The salivary fern pattern was compared with the different phases of the menstrual cycle. In the ovulation phase, estrogen crystals which formed clearly were observed in saliva, whereas in other phases few crystalline structures were visible. The results suggest that the appearance of fern formation may be due to the appearance of surge of estrogenic activity. This is confirmed by the estimation of electrolytes namely sodium, potassium, and subsequently estrogen. The present study emphasizes, that the salivary fern pattern can be used for ovulation prediction, and the test may, therefore, be clinically useful in the prediction of ovulation after suitable modification.

Can a saliva test confirm pregnancy?
It is possible that saliva can show evidence of pregnancy, but the results would not be %100 accurate. When your saliva is viewed through a microscope it shows crystallized "ferning" patterns when your body releases estrogen (during ovulation and right before your period). Your saliva then returns to "normal" once these stages have passed. (Normal saliva shows up as spotted clear liquid when seen through a microscope.) If your saliva continues to show a ferning pattern it may be a sign of pregnancy due to your body releasing more hormones to support the pregnancy. But not all women show this ferning pattern and not all saliva tests can be considered accurate due to the fact that eating or drinking anything prior to the test can contaminate the samples. (These tests should be done first thing in the AM before brushing teeth, drinking, smoking, etc.) Also, as your body prepares for pregnancy it releases hormones at different times so ferning may not show up every day. So in short, yes it is possible that your saliva can show that you are pregnant, but saliva ferning test results can be too unreliable to know for sure. A blood test should be done by your doctor before you can really be certain of pregnancy.
