Lecture 9:male Female Sexual Behaviour

Front 1

does testosterone determine sexual behaviour alone

Back 1

no

Front 2

in some castrated(no T) rats still saw behaviour it was noticed that in these cases the rats had high levels of

Back 2

dopamine-->neurotransmitter/hormone involved in reward pathway

Front 3

many neurotransmitters affect male sexual behaviour

Back 3

true

Front 4

individual differences in sex behaviour ____following castration and T replacement and reason for this

Back 4

retained, reason may be in T receptors or T may affect other systems

Front 5

in males the decrease in sexual behaviour with age is NOT associated with change in hormone conc.

Back 5

true

Front 6

compare male freq of behaviour to level of testosterone

Back 6

peak in freq earlier than decline in hormones, due maybe to life changes ie settling down around 30years. at 50years see decline in testosterone

Front 7

is there interindividual differences in male sexual behaviour

Back 7

yes

Front 8

sexual experience promotes neurogenesis in ____despite increase in stress hormones

Back 8

hippocampus (emotions,learning,memory)

Front 9

acute sexual experience increased __and __ in dentate gyrus

Back 9

cell proliferation,corticosterone(glucocorticoids)

Front 10

chronic sexual experience enhanced cell prolif/neurogenesis without

Back 10

changing glucocorticoid levels

Front 11

sexual behaviour does what to dendrites

Back 11

alters them, increasing size/number of spines

Front 12

sexual experience can affect anxiety like behaviours by

Back 12

decreasing them

Front 13

Frank Beach and three components

Back 13

female sexual behaviour
-three components: attractivity, proceptivity,receptivity

Front 14

the three components linked to

Back 14

estrous cycle, its the estrus phase when components occur

Front 15

estrous cycle is period in cycle when __most likely to happen. Coincides with

Back 15

mating,ovulation when egg cells released from ovary

Front 16

estrous cycle four stages

Back 16

proestrus: follicl development, one or morefollicles of ovary grow
estrus: maturing follicles and estrogen secretions exert influence, female sexually ACTIVE
metestrus: corpus luteum

Front 17

behaviour in estrus may be signaled by

Back 17

visible physiologic changes

Front 18

attractivity and the adaptive functions of it (2)

Back 18

-theoretical construct inferred from observation of behaviour: of female in question,males toward female in question, various masculin responses employed to measure female value as sexual stimulus
-definition=female stimulus value evoking sexual response by male
-bringing male to female &allowing male to identify female reproductive status

Front 19

why is sexual attractivity so necessary

Back 19

estrogen made close to ovulation, attractivity maximizes probability of copulation when female fertile and able to conceive

Front 20

attractivity affected by

Back 20

ovarian hormones being most intense when estrogen secreted in high conc

Front 21

acceptance ratio-->ratio female invitation cause mounting
PROX score-->male moving to be next to female
visual fixation
male erection
male performance of learned response
copulatory behaviours terminating in ejaculation

Back 21

measures of attractivity

Front 22

vocal changes in females occur as a consequence of being

Back 22

in different parts of cycle

Front 23

increased pitch in females means closer to

Back 23

ovulation

Front 24

problem with vocal cue experiment

Back 24

straight line plot not good enough, if plotted polynomially peak is before ovulation

Front 25

two pictures on of woman in reproductive and one when they aren't. Which one did judges rate higher in terms of the woman trying to be more attractive and what problem with study

Back 25

the one where they were in reproductive phase,variability some of judges were female

Front 26

in experiment female wear shirt 3 nights during late follicular (high fertility) phase and another shirt in luteal (low fertility) phase. Then men judge odor as more pleasant/sexy. Results and problem with study

Back 26

rated follicular phase shirts as more pleasant/sexy,condition of wearing shirt variable and should use days to ovulation for more accuracy

Front 27

experiment where hypothesis that breast more symmetric toward ovulation was this proven and what problem with it

Back 27

yes but problem is that how do you pick "random patients" and can't say all ovulation on same day and the polynomial curve actually showed symmetry declined at ovulation

Front 28

Flehmen response

Back 28

-non behavioural cue
-many male mammals check out female genitals before mating elicits Flehmen response-->curling back of upper lip and tilt head back
-purpose to allow chemosignals to reach vomernasal organ

Front 29

Coolidge effect

Back 29

-non hormonal effect
-female less attractive to male male after the bang so many times
-new female male response normal
-not female hormone effect

Front 30

proceptivity

Back 30

flirting

Front 31

proceptive behaviour like attractive occurs during estrus or when

Back 31

female stimulated by exogenous gonadal hormone

Front 32

androgen treatment increases___motivation in female monkey take with grain of salt because

Back 32

sexual,exogenous androgens may convert to estrogen before see behaviour

Front 33

receptivity

Back 33

consent/putting up with it

Front 34

___needed for receptive behaviour but not always good enough

Back 34

estrogen
