Menstruation

Question 1

How do FSH, Oestrogen, and LH and Progesterone all link?

Answer 1

The Pituitary Gland produces FSH, (Maturing the egg) stimulates the Ovaries and produces Oestrogen, (Thickening Uterus lining) which stimulates the Pituitary Gland and produces LH (Ovulation/Releasing egg) and this triggers the hormone Progesterone to prepare the lining once the egg is fertilised,

Question 2

What is the function of Oestrogen?

Answer 2

Needed for puberty, menstrual cycle, pregnancy, bone strength, etc.
Also prevents more FSH being secreted and repairs uterus lining after menstruation.

Question 3

What is the function of Progesterone?

Answer 3

Prepares the lining of the Uterus for a fertilised egg to implant and grow.
Works with Oestrogen to prevent secretion of FSH.

Question 4

What is the Function of FSH?

Answer 4

A hormone which causes eggs in the ovaries to mature.
As well as stimulating the ovaries to make Oestrogen.

Question 5

What is the Function of LH?

Answer 5

A hormone which triggers the release of an egg (ovulation) from the ovary.
