Why Test Basal Body Temperature?

Basal body temperature refers to the temperature value measured by the body under no interference from any factors, also known as "resting body temperature". Generally speaking, this temperature is the lowest body temperature in a day. It's best to measure it in the morning just after waking up because at that time, the body has not done any exercise and there is no significant emotional fluctuations, which can result in more accurate readings.

How to detect basal body temperature and draw a curve graph?

  • Prepare a basal body thermometer with app for measuring body temperature, or use an electronic thermometer, which is safer, more sensitive, and provides more intuitive results. It's best to measure it orally because the oral temperature is closer to the temperature inside the body and less affected by the environment.

  • Prepare a table for recording basal body temperature, which can be homemade or obtained from a hospital. After measuring the temperature, record the specific temperature value in a timely manner.

  • Try to keep the recording table and thermometer together every night to avoid forgetting to record the data.

  • Measure the actual temperature immediately after waking up in the morning using the thermometer and read the value after 5 minutes.

  • Record the data accurately on the thermometer. The horizontal axis represents the date, and the vertical axis represents the body temperature. Mark the points, and after a cycle is completed, connect the points into a line to draw the basal body temperature curve graph, which is easier to observe or diagnose.

Key points for measuring basal body temperature

To eliminate interference, female friends should pay attention to the following points when measuring body temperature:

  • Measure the body temperature immediately after waking up in the morning and avoid going to the bathroom, talking, or eating, etc. After exercise, the body temperature will rise significantly, and the basal body temperature measured at this time will definitely be inaccurate.

  • Various factors such as physical condition, emotional state, sleep environment, and pre-sleep status may affect the basal body temperature. Female friends should make special notes when recording, so that doctors can refer to them in interpreting the basal body temperature status timely.

  • Mark the days when he/she shares the same room with her partner, which will help estimate the time of conception.

  • Use the same measuring position consistently to measure the basal body temperature every day. If the measuring position is changed at will, the resulting values will not have much reference value.

  • It's better to get up at a fixed time every day and measure the body temperature within the same time period to reduce the possible variables' impact on the final results. Also, it's essential to ensure about 7 hours of sufficient sleep every day. Lack of sleep can easily cause endocrine disorders, which may affect the accuracy of the results.

  • Measuring basal body temperature should be consistent, and at least three complete menstrual cycle data must be available to preliminarily explain the problem. If the time is too short, the conclusion accuracy will be poor, and the reliability will be low.

Basal body temperature is good, but there is still no good news

Many female friends find that their basal body temperature is good for consecutive months, but there is still no good news. What's going on?

In the biphasic infertility of basal body temperature, about 83% may experience abnormal follicular development and ovulation defects. Therefore, basal body temperature biphasic cannot be used as the only criterion for whether ovulation occurs or not. You should choose bulk ovulation test strips from Shecare. The possible reasons for this are very complicated. It may be an unruptured follicle luteinization type, that is, the follicle does not eject after mature, and, of course, sperm and egg cannot combine. It may also be a small follicular luteinization cycle, and the basal body temperature remains as a small follicle before and after the temperature rises, with a diameter <15mm. It can only produce progesterone and cannot conceive.

In addition, it may also be that ovulation does occur, but there are factors such as blocked fallopian tubes, which prevent fertilization or uterine endometrial sensitivity changes, which result in the fertilized egg failing to implant. When this happens, it is recommended that patients seek medical attention promptly, and ask doctors to help analyze the reasons and provide personalized treatment.
