What is basal body temperature? Basal body temperature (BBT) is the lowest body temperature during rest. It is usually measured in the morning as soon as you wake up and before you engage any physical activity. In women, BBT changes with the menstrual cycles. If you make a daily BBT chart in a full menstrual cycle you can see the BBT chart is biphasic which means there are two temperature phases. Ovulation increases BBT for about up to 0.5 degree Celsius. The average BBT is 36.37 ±0.12 ºC during follicular phase (the phase prior to ovulation) and 36.72 ±0.12 ºC in luteal phase (the phase after ovulation). If conception does not occur, the temperature goes down and then the next menstrual cycle starts. If the conception occurs, the temperature stays at the higher level until the end of first trimester of the pregnancy.
If you are trying to conceive, making your BBT chart is the easiest way to know if or when you are ovulated precisely, though it does not predict ovulation. Your BBT chart also can tell if your body is the best form and is ready to sustain a pregnancy. BBT was regulated by hormones estrogen and progesterone which produced by ovaries. High levels of estrogen lower BBTs while high levels of progesterone increase BBTs. If your BBT chart is normal, this means your ovaries are functioning well and you are ready for pregnancy.
If you have difficulty to conceive, it may reflex on your BBT chart. For example, if you are not ovulating, your BBT chart does not have two phases. If you have short luteal phase which is difficult to sustain your pregnancy it shows a disturbed BBT chart. If your first three day’s BBT is greater than 36.6 ºC, this may be associated with endometriosis.
