Chapter 6 Female Sexual Behavior

Front 1

What is an estrus cycle?

Back 1

Period which female will permit copulation

Front 2

Define behavioural estrus

Back 2

Period of the reproductive cycle that female will mate. Exhibit motivation and behavior that faciliates reproduction

Front 3

Define vaginal estrus

Back 3

Estrogen have stimulated the reproductive tract sufficently to support a pregnancy

Front 4

What does anestrous mean?

Back 4

The rest of the cycle where the female will not mate; can harm the male if they try to mount

Front 5

What is vaginal cytology?

Back 5

Study of the cells shed in the vagina; indicates hormonal state of animal

Front 6

Describe what lordosis is.

Back 6

Female mating posture; curvature of spinal cord, arched back, and deflect her tail

Front 7

Is female sexual behavior active or passive? Why?

Back 7

Beginning, widely assumed that passive. But this might be because of observer bias, immobility of lordosis position. Female might be more active in a natural condition.

Front 8

What are the components of female sexual behavior?

Back 8

Attractivity, Proceptivity, Receptivity

Front 9

What is attractivity?

Back 9

Stimulus value of a female for a given male; measured in relational terms; male's effort to get to the female

Front 10

Proceptivity

Back 10

Extent to which female initiates copulation;crossing barriers

Front 11

Receptivity

Back 11

State of responsiveness to sexual initiation; Lordosis

Front 12

Follicular phase

Back 12

Begins at the end of menstruation; and ends at ovulation; high blood levels of estrogen and follicles develop

Front 13

Luteal phase

Back 13

Begins at ovulation till onset of menstruation; high levels of progesterone

Front 14

What kind of face would a woman prefer during the follicular phase of cycle?

Back 14

Masculine face

Front 15

What kind of face would a woman prefer during luteal phase of cycle?

Back 15

Feminine Face

Front 16

Hormone that is important for attractivity, receptivity and proceptivity?

Back 16

Estrogen

Front 17

Flahmen response

Back 17

Mammals like horses, in response to chemical signals obtained through investigation, extend their neck, curl up their upper lips, exposing its gums, and presses its tongue against the roof of its mouth, allowing to force the chemosignals into vomeronasal organ

Front 18

Is it benefical to pace female sexual behavior?

Back 18

Yes, higher number of successful pregnancies with lesser intromissions compared to non-paced behavior

Front 19

Which phase are follicles developing?

Back 19

Follicular phase

Front 20

Pseudopregnancy

Back 20

Reproductive system acts like it is pregnant; high levels of progesterone

Front 21

In which phase are lots of progesterone produced?

Back 21

Luteal phase

Front 22

What is necessary for blastocyst implantation?

Back 22

Pseudopregnancy

Front 23

How many types of female reproductive cycles are there?

Back 23

3

Front 24

Describe Type 1 and its subtypes

Back 24

All spontaneous ovulation and pseudopregnancy; (1.1A) copulation limited to periovulatory period; (1.1B) Copulation may occur throughout the cycle; (1.2)copulation limited to periovulatory period, more than 5 weeks

Front 25

Describe Type 2

Back 25

Induced ovulation but spontaneous pseudopregnancy

Front 26

Describe Type 3

Back 26

Spontaneous ovulation, induced pseudopregnancy

Front 27

Which female reproductive cycle does short-lived species display?

Back 27

Type 2.1/3

Front 28

Lee-boot effect

Back 28

When housed 4/cage with no males present, female mice display longer estrus cycle due to lengthening of diestrous stage

Front 29

Whitten effect

Back 29

Male odor induces estrous behavior within 48hr in group-housed female mice.

Exposure to male urine induces GnRH release and estrus;

Cage with no males present, female mice suspend estrous cycleExposure to female urine suppresses GnRH release and estrus

Front 30

Bruce effect

Back 30

Pregnant mice abort their fetus if exposed to stranger male for >48 hours; Exposure to male urine induces GnRH release and estrus

Front 31

Vandenbergh effect

Back 31

Female juvenile mice exposed to adult males mature earlier; exposure to male urine induces GnRH release and puberty

Female juvenile mice exposed to adult females mature later; exposure to female urine inhibits GnRH release and puberty

Front 32

What happens to LH if there is no estrogn produced?

Back 32

LH surges

Front 33

Ovarian cycle in primates

Back 33

Only one follicle usually develops in a cycle; corpus luteum is maintained after each ovulation

Front 34

How does estrogen affect lordosis?

Back 34

Estrogen causes the production of estrogen and progesterone receptors in brain. Blocking these steroid receptors block lordosis

Front 35

Role of spinal cord

Back 35

Produces motor response

Front 36

Role of lower brain stem

Back 36

Integrates posture across segments

Front 37

Role of Hypothalamus

Back 37

Responds to steroid hormones; produces proteins and peptides

Front 38

Role of forebrain

Back 38

Inhibits lordosis

Front 39

What is the relationship between norepinephrine and female sexual behavior?

Back 39

Positive

Front 40

What is the relationship between GABA and female sexual behavior?

Back 40

Positive

Front 41

What is the relationship between CRH and female sexual behavior?

Back 41

Negative
