Fertility awareness or natural family planning has been used successfully since the 1930's to predict woman's fertile days. These natural methods are based on the fact that fertilization is most likely to occur around the time of ovulation. Intercourse is avoided during those times when a woman is fertile, thus preventing conception. In this paper we present a fertility information appliance that combines ovulation, symptom-thermal and LH hormone methods. The appliance is implemented using a neurofuzzy approach. The device has other features such as PPP and TCP/IP protocols implementation for emails and file transfer via a modem.
