A method and apparatus for predicting the fertility status of a human female subject. The onset of menstruation of the subject is noted. Daily determinations are made of the subjects eccrine sweat pH, beginning not more than 4 days following menstruation. The start of the fertile period is determined as a function of a significant decline in pH, followed by a sharp rise. The peak of this pH rise is indicative of imminent ovulation, which generally coincides with a second pH decline of variable degree. The apparatus provides provisions for automatically taking the pH readings, analysing them, and displaying to the user the daily fertility status.

Procédé et appareil de détermination de l'état de fécondité d'une femme. On constate le début de la menstruation du sujet. Une détermination quotidienne du pH de la sueur exocrine du sujet, commencée pas plus de quatre jours après la menstruation, est ensuite effectuée. On détermine le début de la période féconde en fonction d'une baisse significative du pH, suivie d'une augmentation prononcée. La crête de cette augmentation du pH indique une ovulation imminente, qui coïncide généralement avec une seconde baisse variable du pH. Cet appareil prévoit des moyens pour réaliser des lectures automatiques du pH, les analyser et afficher à l'utilisatrice son état de fécondité quotidienne.
