Abstract: This invention relates to a method and system for detecting ovulation in female's menstrual cycles, which involves collecting menstrual cycle information of a subject to calculate ovulation interval dates. Daily heart rate waveform signals are used to obtain heart rate-related physiological parameters, including the first cumulative power (LF), second cumulative power (HF), standard deviation of interbeat intervals (SDNN), root mean square of successive differences (RMSSD), cumulative power ratio (LF/HF), and heart rate parameter ratio (SDNN/RMSSD). The invention selects the day with the highest cumulative power ratio (LF/HF) and heart rate parameter ratio (SDNN/RMSSD) within the ovulation interval as the day of ovulation.
