which causes a drop in female hormone levels? the onset of the menstrual flow the release of an egg from the ovary the thickening of the uterine wall the failure of an egg to be fertilized

Answer

Brief Explanations:

When an egg is not fertilized, the corpus luteum (which produces female hormones like progesterone and estrogen) degenerates. This leads to a drop in female hormone levels, triggering menstruation. The onset of menstrual flow is a result of low hormone levels, not a cause. Egg - release from the ovary (ovulation) is associated with a hormonal shift but not a drop in overall female hormone levels at that moment. The thickening of the uterine wall is due to rising hormone levels.

Answer:

the failure of an egg to be fertilized
