Conference paper


So-called natural family planning methods (NFPs) — we prefer the less misleading and more descriptive term of “self-observation methods” (SOMs) — are still a matter of controversy (Döring 1985). Thus a more rational understanding and attitude regarding their physiological foundations, advantages, and disadvantages seems desirable. For this purpose we have introduced a noninvasive method of hormonal ovulation detection, the radioimmunological determination of salivary luteinizing hormone (LH), in order to enable more large-scale studies to be carried out without putting an undue burden upon the volunteering women. It was also shown that the salivary LH peak may serve as a suitable indicator of ovulation. The overall correlation of salivary LH to serum LH was found to be highly significant (r = 0.788, n = 60, P <0.0001) (Loewit et al. 1985) and the salivary LH peak was centered ±0.5 days around the time of ovulation in 9/15 (60%) and ±1.5 days in all of 15 sonographically monitored ovulations (Loewit et al. 1987). With this methodology at hand we have started to evaluate the theoretical reliability of SOM parameters and rules. Preliminary results concerning the correlation of cervical mucus pattern and basal body temperature (BBT) with the salivary LH peak in around 270 cycles so far and of the respective variations of the cervix uteri in 115 cycles are reported here.
