Very early on Baby-Comp and later Lady-Comp were submitted for clinical tests. The results were always used to enhance and further develop the devices. In addition, our statements for the Pearl-Index are not based on our own studies but are the result of many clinical studies.

Summary of published studies:

1. a) Test on preciseness of the temperature readings
Result: Temperature reading highly precise p2 0,01.
b) Test on prevention compared with clinical testing
Result: no unwanted pregnancies during green days
c) Test about planning
Result: 2 out of 5 conceived during the test
Rhodes Island 1988, Prof. Freundl, Frank-Herrmann, Toncaboni

2. Test fertile women. Compared with clinical testing.
Definition: 6 Days are fertile
Result: Lady-Comp found temperature shift in each cycle.
Number of fertile days 11.1 +/- 3.
Length of cycles 25 –35. No pregnancy on green days
Barcelona Congress 1992, Prof. Freundl,Bauer,Bremme,Doering, Herrmann

3. Clinical test and research on Hormone and temperature shifts.
Result: They do correlate and Baby-Comp can improve reliability, acceptability and application of BBT in fertility investigation.
Amsterdam 1992, Prof. Martinez, V.Hooff, Schoute, V.D.Meer

4. Test on women sterile for 3-8 Years. Baby-Comp compared with clinical testing
Result: 100% match on luteal deficiency, anovulatory cycles and pregnancies.
Clinical testing found 86% of the ovulation's, Baby-Comp 80%
Sassari 1997, Prof. S.Dessole, Fadda, Rosas, Scapinelli, Inaudi, Ambrosini

5. Test of 683 women over 24 months, 12213 cycles completed.
Result: see test # 8
Not yet Published
Birmingham 1997, Prof. Freundl

6. Clinical testing and comparison with Baby-Comp
Result: Perfect match between clinical findings and fertility indications of Baby-Comp
Not yet Published
Erlangen 1994, Prof. Wildt

7. Clinical fertility test vs. Baby-Comp.
Results: In no case did Baby-Comp miss the beginning of the fertile time, Cycle disturbances were detected and treated correctly.
