Patient's question:
NoDoctor's answer:
Hello, basal body temperature is the temperature measured in bed after waking up without any physical activity in the morning. It indirectly reflects the function of the ovaries. Before ovulation, basal body temperature is lower than normal body temperature. During ovulation, the temperature drops continuously by 0.1-0.2°C. After ovulation, the temperature rises immediately by 0.3-0.5°C and remains elevated until just before menstruation; 1-2 days before menstruation, the temperature may drop again. This is known as the biphasic curve, indicating ovulation. If the temperature remains consistently at the same level, it is called a monophasic curve, indicating no ovulation. The subject must sleep for 6-8 hours before measurement, and the measured data should be recorded on a coordinate paper daily. Continuous measurement should be conducted for 2-3 menstrual cycles.
