  1. Chapter 6 Female Reproductive Behavior

  2. 6.2 Nonestrous females are not motivated to mate

  3. George Nicholaus Papanicolaou – discerned a test to identify external markers of the 16 day estrus cycle in guinea pigs. Very similar tests show the same patterns in other rodents, including the four day cycle seen in the Norway rat.

  4. 6.4 Cyclic changes in vaginal cell types Vaginal lavage – technique using physiological saline to extract cells from the vaginal

  5. 6.5 Cyclic changes in ovarian structure


  6. 6.7 Lordosis makes successful copulation possible

  7. 6.8 Female initiation of sexual interactions

  8. 6.9 Estrogen mediates proceptivity, attractivity, and receptivity (Part 1)

  9. 6.9 Estrogen mediates proceptivity, attractivity, and receptivity (Part 2)

  10. 6.9 Estrogen mediates proceptivity, attractivity, and receptivity (Part 3)

  11. 6.10 Estrogen increases attractivity Male acceptance ratio (MAR) is the number of female solicitations the male responds to. Males will have a higher MAR in ovariectomized females receiving replacement estrogen.

  12. 6.11 A three-chamber preference test Female tethered three chambered preference test is designed to assess male response. Other variations exist.

  13. 6.14 Estradiol enhances proceptivity in the absence of male interest Females would increase their initiation of male interest (proceptivity) when estradiol is replaced even off season.

  14. 6.15 Endocrine control of receptivity can be affected by social factors Comparison of Rhesus monkeys in different size areas.

  15. 6.16 A breeding deme

  16. 6.17 Female pacing of copulation

  17. 6.18 Paced mating enhances reproduction

  18. 6.19 The human menstrual cycle (Part 1)

  19. 6.19 The human menstrual cycle (Part 2) Corpus luteum development is associated with the rise in progresterone.

  20. 6.19 The human menstrual cycle (Part 3)

  21. 6.20 The castration response

  22. 6.21 The ovarian cycle in rats

  23. 6.22 Receptive fields in the flanks increase in size during estrus

  24. 6.23 The neural basis of lordosis (Part 1)

  25. 6.23 The neural basis of lordosis (Part 2)

  26. 6.26 Lordosis does not occur in progesterone receptor knockout mice

  27. 6.27 Five neural modules that mediate lordosis
