Embodiment Construction

[0024] In cases where a woman ovulates to allow the egg to remain unfertilized for a certain length of time (usually fourteen days), the infertile egg will be expelled from her body (menstruation), and her basal body temperature will then drop. Even though she is not menstruating due to some hormonal disturbance, her basal body temperature is lowered. In the case where the fertilized egg remains, her basal body temperature does not drop, remaining at a high level for a long period of time. When a high temperature cycle lasts 21 or more days, she is presumed to be pregnant.

[0025] The present applicant has filed patent application No. H 11-258358, which proposes to make a judgment about which physiological stages of a woman's monthly physical state in terms of bioelectrical impedance. In particular, the bioelectrical impedance value is closely related to the women's basal body temperature; the bioelectrical impedance value remains high when the basal body temperature remains...

Abstract

Disclosed is a pregnancy possibility determining method and apparatus in which a decision of possibility of pregnancy can be made in terms of how the values of bioelectrical impedance vary after expiration of a certain length of time since the ovulation day.

Description

technical field [0001] The present invention relates to a method and apparatus for determining the likelihood of pregnancy. Background technique [0002] Women use a thermometer to measure their basal body temperature daily, and then they can make a determination of the likelihood of pregnancy based on the chronological shift or history of the basal body temperature. figure 1 Represents the chronological transition or history of the basal body temperature of a woman with a twenty-eight day long menstrual cycle. As shown, the monthly phases women have are closely related to the chronological transition or history of basal body temperature. The temperature curve (a) represents the transition of the normal body state from the low humidity period to the high temperature period of the ovulation day, and conversely from the high temperature period to the low temperature period of the ovulation day. In the case of cessation of ovulation, the temperature curve (b) shows little or ...
