- What are the effects of FSH?
- It causes menstruation.
- It causes the ovaries to secrete oestrogen. ✓
- It causes the follicle containing an egg to mature. ✓
- It causes progesterone to be released.
- It causes the uterus lining to thicken.
-
- Put these steps of the menstrual cycle in the correct order.
- 1⇔uterus lining breaks down and menstruation takes place
- 2⇔uterus lining reforms and thickens
- 3⇔ovulation
- 4⇔uterus lining continues to thicken as egg travels down the fallopian tube
- 5⇔uterus lining is maintained ready for a fertilised egg
- Which hormone causes ovulation to take place?
- 'LH' ✓
- Which hormones cause the mature follicle to break down and secrete progesterone?
- LH and oestrogen
- FSH and oestrogen
- Oestrogen and progesterone
- LH and FSH ✓
- Progesterone and FSH
-
- A fall in which hormone triggers menstruation?
- 'Progesterone' ✓
Order the steps.- 1⇔FSH is released from the pituitary gland and travels to the ovaries.
- 2⇔A follicle matures and oestrogen is released.
- 3⇔Oestrogen causes uterus lining to thicken, LH to be released and inhibits FSH.
- 4⇔LH causes ovulation.
- 5⇔FSH and LH cause the mature follicle to break down and secrete progesterone.
- 6⇔Progesterone maintains uterus lining and prevents the secretion of FSH and LH.

Lesson Details
Key learning points
- FSH causes follicle maturation and secretion of oestrogen by the ovaries.
- Oestrogen causes thickening of uterus wall, secretion of LH by the pituitary gland and inhibits the release of FSH.
- LH causes ovulation; FSH and LH cause the mature follicle to break down and secrete progesterone.
- Progesterone prepares uterus lining for implantation of fertilised egg; stops secretion of LH & FSH by pituitary gland.
- Fall in progesterone causes menstruation.
Common misconception
That the menstrual cycle is not linked with reproduction; that hormones only control mood.
Diagrams to show the clear effect of hormones on changes in the menstrual cycle and discuss the importance of the process to fertilisation.
