Male Reproductive Behaviour 5

Question 1

What is the consummatory and appetitive behaviour in mating?

Answer 1

Appetitive involves things such as courtship

Consummatory involves the act of mating- copulation

Question 2

If an aromatase inhibitor reduced both appetitive and consummatory behaviour in males what does that indicate?

Answer 2

Both are activated and maintained by oestrogens derived from testosterone

Question 3

What are the 3 different categories of behaviour through POM lesioning?

Answer 3

Normal ASB, weak CSB
Normal ASM, no CSB
No ASB, no CSB

Question 4

What happens if the preoptic area (POA) is lesioned?

Answer 4

Lesioning of the POA reduces or eliminates consummatory behaviour but not appetitive

Question 5

Give an example of a study where mice are effected by social cues in mating behaviour:

Clue- olfactory cues

Answer 5

Given wintergreen odour in the presence of a female

Responded to the wintergreen odour in the same way that untrained mice responded to female presence by increased hormone concentrations

Associated the odour with mating behaviour

Question 6

What is the Coolidge effect?

Answer 6

The idea that males would rather mare with multiple females than the same female every time

Question 7

What was found when looking at the mechanisms that lead to different phenotypes in male manakin birds?

Answer 7

There is an activational effect of androgens rather than oestrogens

Androgen receptors are involved in fine motor control of the muscles producing the wing snaps- could explain the individual difference
