Figure 43.17 Which of the following statements about the menstrual cycle is false? Progesterone levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. Menstruation occurs just after LH and FSH levels peak. Menstruation occurs after progesterone levels drop. Estrogen levels rise before ovulation, while progesterone levels rise after.

Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false?
