Q

Dr. George Papanicolaou

A

discovered that a change in vaginal cytology was closely correlated with ovarian function, began studying menstrual cycle and noticed abnormal cell types from cervical samples, became the diagnostic tool known as the Pap test

Q

initiation of sexual interactions in rodents

A

initiate mounting the female hops near the male and then hops away, ear wiggling, after intromission the female will pause/stop these initiation behaviors

Q

components of female sexual behavior

A
  1. attractivity
  2. proceptivity
  3. receptivity
22
Q

attractivity

A

the stimulus value of a female to a particular male, a hypothetical construct which must be inferred by observation of a conspecific behavior

23
Q

proceptivity

A

the extent to which females initiate copulation, consists of both her overt behavior and her underlying motivational state

24
Q

receptivity

A

the stimulus value of a female for eliciting an intravaginal ejaculation from a male conspecific (responsiveness to the sexual initiation of another individual)

25
Q

estrogen and proceptivity example

A

female rhesus monkeys taught to press a bar 250 times in 30 minute window for access to a male for 1hr, mean access time was lowest right around ovulation (when estrogen is highest)

26
Q

estrogen and attractivity example

A

mean mounting rate was highest around the estradiol peak

27
Q

estrogen and receptivity

A

of ejaculations was highest around the estradiol peak, time to ejaculation was lowest around the estradiol peak

28
Q

a real world example of estrogen and FSB

A

tipping rates for female strippers
1. $335 around ovulation (highest E)
2. $260 during luteal phase
3. $185 during menstruation

29
Q

what is attractivity and how is it measured

A

not who the female is attracted to, whether the female is attractive to a male, often measures through preference

30
Q

estrogen and attractivity

A

female primates in estrous experience swelling of the perigenital skin, olive baboon males spend more time looking at and approaching females with swollen perinea than other females

31
Q

ovariectomy + estrogen treatment results

A

increases attractivity in dogs

32
Q

male acceptance ratio

A

the proportion of female solicitations that result in male mounting behavior

33
Q

chemical cues and attractivity

A

major sources of chemosensory cues are from the urinary and vaginal secretions of females in estrous

34
Q

who processes chemosensory cues through vomernasal organ (VNO)

A

ungulates, carnivores, rodents

35
Q

VNO and humans

A

not necessary for pheromone detection, thought to be reduced or absent in higher primates

36
Q

behavior and attractivity

A

males spend more time with females actively seeking copulation by their presentation behavior than with those who do not show as much presentation behavior

37
Q

what is proceptivity

A

all appetitive sexual behaviors, sexually solicitous behaviors that initiate sexual union, sexual motivation/libido/sex drive

38
Q

how is proceptivity measured

A
  1. affiliative behaviors
  2. # of solicitations prior to intromission
  3. alternating approach and withdrawal
39
Q

affiliative behaviors

A

trying to get close to males

40
Q

of solicitations prior to intromission

A

solicitations seen in many species including birds, fish, reptiles, can also include vocalizations and head bobbing

41
Q

alternating approach and withdrawal

A

approach may include anogenital sniffing by the female, or mounting, seen in rodents, ungulates, canines, primates

42
Q

estrogen and proceptivity

A

estradiol increases proceptivity in the absence of male interest

43
Q

what is receptivity

A

consummatory phase of mating behavior, female reactions which are necessary and sufficient for fertile copulation

44
Q

what does receptivity look like

A

all non-primates show a species-specific mating posture, as do most nonmammals

45
Q

how is receptivity measured

A

mostly expressed as a ratio between a male’s attempts to mate with a female and his success at doing so

46
Q

receptivity of rats measured by

A

lordosis quotient

47
Q

receptivity of dogs measured by

A

rejection coefficient

48
Q

receptivity of primates measured by

A

acceptance ratio

49
Q

receptivity and estrogens

A

mating posture disappears in most ovariwctomized females, estrogens seem to mediate all of these different components including receptivity
