Health: temperature changes and menstrual cycle

Menstruation is the well-known physiological phenomena in the menstrual cycle, the woman's body temperature is a level of change in menstruation is often the first half of the lower temperature, the latter half of the body temperature slightly higher, and why? Apart from ovarian ovulation, but also secrete hormones, mainly estrogen and progesterone. Preovulatory follicles mainly for the growth, maturity, at this time mainly to estrogen secretion. Follicle after ovulation the corpus luteum formation, physical fitness and Huang have two hormones, estrogen and progesterone, and progestin can stimulate the central body temperature, the temperature rose slightly, after ovulation women in the normal body temperature can be increased 0.3-0.5 degrees Celsius. People by checking the body temperature can be measured based on temperature changes, in the longer time is 6-15 hours of sleep, woke up, had not yet carried out any activity, measured by the temperature of their own, will be measured by the temperature rise recorded in the foundation Single-temperature, day by day, painting a curve. Normal curve is slightly smaller than before ovulation, ovulation period of the lowest and progesterone after ovulation due to the heat, the temperature higher than the follicular phase. So the normal curve of a duplex, no lack of ovulation and menstrual cycle regularity progesterone without the above changes, temperature and consistent with a single-phase. The significance of the temperature changes: 1. Duplex-type body temperature can be used as an important indicator of ovulation, ovulation time before the change in temperature duplex 2-3 days, the single-phase body temperature can be sure no ovulation and luteal formation. 2. Duplex-temperature high-temperature phase (luteal phase) over 16 days and above, that is possible to conceive, for the treatment of infertility patients Hi Katherine, a history of habitual abortion, protective measures should be taken at this time. 3. Temperature curve is generally believed that the warm period should not be less than 12 days, should not be lower than the increase rate of 0.3-0.5 degrees Celsius, which is otherwise inadequate luteal function.
