Ovulation Detection by Internal Cranial Temperature Measurements

A simple method for recording a patient´s internal cranial temperature is described. Using these measurements it is shown that the drop and rapid rise in basal temperature indicative of ovulation can be easily detected and recorded. The superiority of cranial temperature over oral temperature is demonstrated by indicating the occurrence of ovulation one full day before a like indication in oral temperature. Evidence is also given for choosing cranial over rectal temperature for use in detecting ovulation.
