The document discusses how hormones influence human behavior. It identifies androgens like testosterone, and estrogen and progesterone as key hormones. Androgens promote male sexual and reproductive functions as well as muscle growth. Estrogen helps maintain bone strength and heart health while progesterone supports pregnancy. Higher exposure to androgens in development makes boys prefer male toys, while estrogen makes females more attractive by stimulating production. Progesterone either stimulates or inhibits sexual receptivity depending on its levels. In summary, hormones play an important role in influencing human behavior and characteristics in both males and females.

3. Three main points
0 (a) The hormone that influence
human behaviour.
0 (b) The function of the hormone.
0 (c) How the hormone affect
human behaviour.

4. 1.The hormone that influence
human behaviour.
Androgen
0 Also called androgenic hormone or testoid
0 Androgens are the group of sex hormones that give
men their ‘male’ characteristics.
0 The major androgen is testosterone.

5. Oestrogen and Progesterone
0 Oestrogen and progesterone are hormones produced
in a women's ovaries before menopause.
0 They both play a critical role in the menstrual cycle
and pregnancy.

6. 2.The function of the hormone.
Function of androgen.
• They are crucial to male
sexual and reproductive
function.
• Androgens promote the
enlargement of skeletal
muscle cells

7. Function of oestrogen &
progesterone.
• Oestrogen helps maintain bone
strength and might prevent heart
disease and also protect memory
before menopause.
• Progesterone plays an important
role in maintaining a pregnancy.

9. 0 The level of exposure to the
hormone androgen during
gestation make boy to more
interest in male-typical
toys.
0 Circulating levels of
androgens can influence
human behaviour because
some neurons are sensitive
to steroid hormones.

10. 0 Hormone progesterone and oestrogen play important role in
female behaviour.
0 Oestrogen can make female more attractive to male by increasing
the production of stimuli.
0 The temporary rise in progesterone will stimulate sexually
receptivity while the prolonged secretion of progesterone will
inhibit sexual receptivity.

11. CONCLUSION
You have listened to three main points
(a) The hormone that influence human behaviour.
(b) The function of hormone.
(c) How hormone affect human behaviour.
• There is no strong evidence that may be
associated with the given points but it all
suggests that sometimes, our bodies know what
the best for us.
