By the analysis of all these parameters, it was established that, out of 213 examinations, FERN test had 15 false positive and 12 false negative results amounting to a total of 7.98% (27) false results.

Out of 213 examinations, GANOP test had 20 false positive and 8 false negative results - a total of 13.15% (28) false results.

In 23 cases, false results of FERN and GANOP tests coincided.

Discussion and conclusions

The possibility of determining fertile and infertile days of the menstrual cycle by using the saliva crystallization test (GANOP TEST) is viable, its validity has been proved and its sensitivity is high. The special validity of this test is its certainty of reaction, specially in the preovulatory period and the period of ovulation.

GANOP test shows a higher tendency towards positivism 4-5 days before the ovulation and 2-3 days after the ovulation.

FERN test of cervical mucus is undoubtedly more precise while GANOP test of the saliva is more sensitive.

Comparable indicators of GANOP test and FERN test in relation to sonographic changes in follicles or their increase indicate that GANOP test is as valid and sensitive as FERN test and correlative values of both tests with regard to sonographic folliculometry are high.

The advantage of GANOP test is its simplicity and possibility for wide application. “MAYBE BABY” - a mini microscope , with instructions, may be easily used by any woman .

A special value of GANOP test is the establishment of fertile and infertile days in the course of the menstrual cycle , as a method of family planning and reduction of unwanted effects to health , and economization in the field of contraception and unwanted pregnancy.

We are of the opinion that GANOP test, owing to its simplicity and validity, deserves a systematic application in determining fertile and infertile days in the course of the menstrual cycle.

A more extensive study is needed in order to judge real values and scope of application of this test. In so far as the real value of the test is established and confirmed in course of time, brilliant clinical future may be predicted for it.
