A method and device to predict ovulation in a female human by measuring changes in the concentration of a number of ions in eccrine sweat is disclosed. The concentration, or changes in concentration, of one or more ions are determined throughout the day and analyzed against predetermined patterns in order to predict ovulation one to five days in advance. This permits the user to more accurately determine commencement of the fertile phase, which for female humans is generally considered to be about four days prior to ovulation to one day after ovulation. The concentration of the ions measured include sodium (Na+), potassium (K+), ammonium (NH4+), calcium (Ca2+), chloride (Cl-) and nitrate (NO3-). To further increase the accuracy of the reading, a large number of readings can be obtained throughout a day and statistically analyzed to determine the change over time. In addition, the concentration of two or more ions can be obtained to increase accuracy. Ratiometric measurements between two or more ions can be determined to increase accuracy and account for ion accumulation on the skin. Ratiometric measurements between ammonium (NH4+) and calcium (Ca2+) have been found to provide more distinct patterns because the concentration of these two ions change in opposite directions during the relevant period preceding ovulation.

L'invention concerne un procédé et un dispositif pour prévoir l'ovulation d'une femme en mesurant les variations de concentration du nombre d'ions dans sa sueur eccrine. La concentration, ou les variations de concentration, d'un ou de plusieurs ions sont mesurées durant toute une journée, puis analysées au regard de modèles déterminés pour prévoir l'ovulation un à cinq jours à l'avance. Ceci permet à l'utilisatrice de déterminer plus précisément le début de sa phase fertile, qui, chez la femme, est généralement considérée comme s'étendant environ quatre jours avant et un jour après l'ovulation. La concentration des ions mesurés comprend le sodium (Na+), le potassium (K+), l'ammonium (NH¿4?+), le calcium (Ca¿2?+), le chlorure (Cl-) et le nitrate (NO¿3?-). Pour préciser davantage la lecture, un grand nombre de relevés peut être effectué durant une journée et analysé par statistiques pour déterminer les variations dans le temps. En outre, la concentration de deux ions ou plus peut être obtenu pour accroître la précision. Des mesures ratiométriques entre deux ions ou plus permettent d'augmenter la précision et le rapport de l'accumulation d'ions sur la peau. Des mesures ratiométriques entre l'ammonium (NH¿4?+) et le calcium (Ca¿2?+) ont prouvé pouvoir fournir des modèles plus clairs, car les concentrations de ces deux ions changent en sens opposé pendant la prériode pertinente précédant l'ovulation.
