Ovulation is for conception, if there is no conception, menstruation will occur normally, entering another menstrual cycle. The corpus luteum in ovaries is a structure generated for conception, providing the necessary hormones for embryonic growth. If not fertilized, the corpus luteum will slowly shrink. Basal body temperature can reflect this cyclic change and can be seen as an indicator of women's reproductive health. If there are menstrual problems or infertility issues, basal body temperature is the most commonly used diagnostic tool.
Women with menstrual disorders, infertility, and developmental abnormalities should measure basal body temperature under the guidance of a physician. Generally, normal women of childbearing age do not need to monitor basal body temperature. Girls before puberty and menopausal women also do not need to measure it.
After ovulation, the basal body temperature will rise by 0.5 to 1.0 degrees and maintain this temperature under the action of hormones in the body. After pregnancy, the basal body temperature still remains elevated. If not pregnant, menstruation will occur, and the basal body temperature will drop back to the level before ovulation. If there is no ovulation, there will be no increase in basal body temperature, and the basal body temperature will remain at its base level.
Every morning after waking up, put the smart basal thermometer that was placed beside you the previous day into your mouth to measure the oral temperature for 5 minutes. The measurement time should not be too short. Before measurement, try not to go to the bathroom, eat or drink. In short, avoid physical activity before measurement to ensure accuracy. Try to measure it every day and do not miss any days. In addition to recording the temperature every day, record whether there is sexual intercourse and whether there is menstruation. There are many basal body temperature record forms available for download and printing on the internet. Many mobile apps also offer convenient basal body temperature recording tables.
Use a family care thermometer, and prepare it the night before and place it next to your pillow for use in the morning. Please keep it in a safe place to avoid breaking it or injuring yourself when turning over.
Avoid using the armpit temperature because it is unstable.
It is not clear whether an ear thermometer can replace a mercury thermometer to measure basal body temperature.
Be sure to avoid physical activity before measuring. Even slight physical activity can cause a rise in body temperature.
Persist in measuring every day. Sometimes one menstrual cycle cannot explain the problem, and two or three menstrual cycles need to be tested.
The accuracy of using basal body temperature to judge ovulation is about 60% - 70%. It can be used together with ovulation test strips, hormone measurements, etc. to improve the accuracy of ovulation detection.
Sometimes, basal body temperature needs to be combined with other tests for judgment. Therefore, guidance from experienced physicians is very important.
Accurately recording basal body temperature is very helpful for judging ovulation and diagnosing menstrual disease. However, due to various factors, the overall accuracy of basal body temperature is about 60% - 70%. Other methods of testing ovulation, such as ovulation test strips and hormone level measurements, have almost the same accuracy. If these methods can be combined, the accuracy of detection can be significantly improved.
Of course, the most accurate method for monitoring ovulation is transvaginal ultrasonography, which is used more frequently in assisted reproduction. However, there are cost and feasibility issues with ultrasound examinations, and it is currently not recommended to use ultrasound monitoring to replace convenient and feasible methods such as basal body temperature monitoring. Physicians will recommend appropriate methods based on specific situations.
