An Individual-based Program for Cycle Prediction

MENSTRUA is a Charity-Ware MS-DOS program requiring a color monitor and an 8086 or higher machine. The purpose is to allow an individual female to enter information about her menstrual cycle, including dates of onset of the period, and characterization of types of days throughout the cycle and use this individual-based information to: predict the probable day of ovulation, the probable beginning of the next menstrual cycle, the probable fertile days of the next cycle, and graph the past history of day types throughout the cycle. Ovulation prediction allows for the calendar method as well as the temperature method to be used, if the user has temperature data available. Partial support for the development of this program came from the National Science Foundation, Undergraduate Curriculum Development Grant USE-9150354 to the University of Tennessee.
