Abstract
A method of providing warning of the onset of the fertile phase of the human ovulation cycle, involving measurement in absolute or relative terms of the body fluid concentration of an analyte such as estradiol or a metabolite thereof wherein if in the current cycle a concentration measurement conducted at about the termination of menses reveals a body fluid concentration that is typical of that found in the body fluid of an average human female subject about 3 days prior to the time of ovulation during a 28-day cycle, the current cycle is immediately declared to be in its fertile phase. Where the a analyte is E3G, the E3G concentration measurement is conducted on at least one or numerical days 4 to 7 of the current cycle, counting from the onset of menses, and the fertile phase is declared immediately if the E3G measurement reveals a concentration equal to or greater than a threshold concentration chosen in the range of about 25 to about 35 ng/ml.
