Patient's question:
NoDoctor's answer:
According to your description, the oral body temperature measured immediately upon waking up in the morning without any activity (such as speaking, eating, or getting out of bed) is connected by date to form a curve, known as the basal body temperature curve. In women with ovulation, the basal body temperature is lower in the first half of the menstrual cycle and higher in the second half (after ovulation), with a general difference of about 0.5°C between the two. This results in an upward and downward fluctuation, known as a biphasic change, on the basal body temperature curve. Three cycles can be measured.
