| 1. | She can improve detection of ovulation by recording her basal body temperature.
|
| 2. | Fig . 2 Example of a basal body temperature chart.
|
| 3. | A woman's basal body temperature rises sharply after ovulation, as estrogen production decreases and progesterone increases.
|
| 4. | Tracking basal body temperatures is a more accurate method of estimating gestational age than tracking menstrual periods.
|
| 5. | Basal body temperature is the lowest temperature attained by the body during rest ( usually during sleep ).
|
| 6. | When she ovulates, her basal body temperature rises about one degree and remains elevated until her next period.
|
| 7. | Computerized devices that interpret basal body temperatures, urinary test results, or changes in saliva are called fertility monitors.
|
| 8. | Females near ovulation experience changes in the cervix, in mucus produced by the cervix, and in their basal body temperature.
|
| 9. | The action of progesterone increases basal body temperature by one-quarter to one-half degree Celsius ( one-half to one degree Fahrenheit ).
|
| 10. | Fertility awareness methods are used to discern when these changes occur by tracking changes in cervical mucus or basal body temperature.
