Answer:
Hormone levels generally decrease.
Explanation:
<em>The graph showed that hormone levels after ovulation generally decrease.</em>
The menstrual cycle of women generally have 3 phases which include:
- <em>The follicular phase</em>
- <em>The ovulatory phase</em>
- <em>The luteal phase</em>
The follicular phase is characterized by low levels of oestrogen and progesterone and a slightly high level of follicle stimulating hormone which ensures that follicles within the ovary develop.
The ovulatory phase is characterized by a surge in the luitenizing hormone (which stimulates the release of eggs) and follicle stimulating hormone with a decrease in the level of oestrogen and a gradual increase in the level of progesterone.
The luteal phase is characterized by a general decrease in the levels of luitenizing hormone and follicle stimulating hormone while oestrogen level may remain high.
