I can explain the roles of FSH, LH, oestrogen and progesterone in controlling the menstrual cycle in human females.
Hormonal control of the menstrual cycle
I can explain the roles of FSH, LH, oestrogen and progesterone in controlling the menstrual cycle in human females.
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.
Keywords
