Basal Body Temperature
Basal body
temperature is the temperature taken
immediately upon awakening after a restful night's sleep, twelve
hours after eating, no exercise, no emotional excitement, and under
normal ambient temperature.
Menses cycle and Basal Body Temperature
The cycle is computed from the first day of bleeding. The normal
length of the cycle is about 21 to 35 days. It differs in different
individuals. The average length is about 28 days. The cycle is divided
into three parts by the ovulation day. The follicle period is before
ovulation. This is when the corpus luteum (yellow body) period
is after ovulation. The length of follicle period varies but the
length of the period of corpus luteum period is typically on the
14th day of a 28-day cycle and lasts for 2 days.
The 2nd day after ovulation, because of the corpus luteum formation
in the ovaries and secretes progesterone, the body temperature rises
about 0.6 oC. The body temperature can go up or down.
The high temperature can maintain 12 to 16 days (average 14 days).
If no pregnancy occurs, the corpus luteum becomes atrophied and
stop secreting progesterone and the body temperature drops back
to normal level and the menses resumes. If pregnancy occurs, the
corpus luteum because of the effect of the hormone secreted by the
fetus, continues to secrete progesterone and the body temperature
continue to be high. If the function of the ovaries is not normal,
without ovulation and without forming of progesterone, the body
temperature will continue to be low.
