Patent ID: 7044919

Claim:
A monitoring device for use in conjunction with one or more body fluid testing devices to provide an indication of the time of maximum fertility in the mammalian ovulation cycle, said monitoring device comprising: a) a reading means for reading for reading test signals provided by said one or more testing devices, said reading means being operationally connected to said testing devices, said signals including a signal proportional to the concentration of a first analyte in a body fluid, which first analyte exhibits a detectable concentration change at about the time of ovulation in said cycle, and a signal proportional to the concentration of a second analyte in a sample of body fluid, which second analyte exhibits a detectable concentration change after the commencement of said cycle but before the concentration change of said first analyte becomes detectable; and b) an electronic processing means for interpreting said test signals obtained in a series of tests conducted following the commencement of said cycle, wherein said electronic processing means of said monitoring device is operationally connected to said reading means, said electronic processing means providing an indication that fertility is elevated when said concentration change of said second analyte has been detected, and an indication that fertility is maximum when said concentration change of said first analyte has been detected.
