Reproductive Hormones

Learning Objectives

• Analyse the role of hormones in the reproductive system

• Describe the process of gametogenesis

• Examine the four stages of the oestrous cyle

What do you know already?

Open Ended

How many reproductive hormones can you name?

Multiple Choice

The two hormones that maintain the lining of the uterus are:

• FSH and Oestrogen

• LH and Oestrogen

• Oestrogen and Progesterone

Multiple Choice

What hormones are released by the pituitary gland?

• FSH, Oestrogen, LH and Progesterone

• FSH, Oestrogen and Progesterone

• LH and FSH

• Oestrogen and Progesterone

Multiple Choice

The hormone that stimulates follicle development is:

• Testosterone

• FSH

• LH

• Oestrogen

Multiple Choice

Ovulation is triggered by a surge in

• FSH

• LH

• Oestrogen

• Progesterone

Multiple Choice

Which hormone is released by the ovaries?

• FSH

• LH

• Oestrogen

• Progesterone

Oogenesis

• FSH stimulates one or more follicles to mature

• LH stimulates mature follicle to produce oestrogen and inhibit LH and FSH production

• Oestrogen (+inhibin) from mature follicle inhibits secretion of FSH so no more follicles mature

• However, an increase of oestrogen levels stimulates LH (peak) and FSH production which leads to ovulation
