A simplified method for recording basal body temperature.
The present study was undertaken to evaluate thermocrystalography as a means of simplifying the recording of basal body temperature (BBT) for the purpose of determining the time of ovulation. Accordingly, BBT, as recorded by disposable oral thermocrystal thermometers manufactured for fever detection, was compared with that obtained by a conventional rectal glass thermometer to establish reliability of the method within the normal temperature range. The readings by both methods were comparable, with a nonsignificant difference between 109 readings when analyzed by a paired t test. A biphasic curve was easily discernable in each of the eight cycles monitored. The use of disposal thermocrystal thermometers provides an alternative to the conventional method of BBT determination, which is faster, easier to read, and potentially more acceptable because of its oral use.
