To study a normal menstruation cycle, the OB-GYN specialist, taking into account the pyrogenic effect of progesterone, measured the patient’s rectal basal body temperature. At what phase of the cycle will the rectal temperature increase by 0.4-0.5°C?
- A. Endometrial desquamation phase
- B. Beginning of follicular phase
- C. Ovulation and beginning of luteal phase
- D. End of follicular phase
- E. End of luteal phase
Hint
Ask when in the cycle progesterone secretion begins to rise, and recall that its thermoregulatory action warms the body soon after that point.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
