This chapter explores the intricacies of female reproductive behavior, focusing on nonestrous females' lack of mating motivation and the estrus cycle in various rodents, particularly guinea pigs and Norway rats. Key topics include cyclic changes in vaginal cell types, the significance of estrogen in proceptivity, attractivity, and receptivity, and the impact of social factors on endocrine control. Insights into the human menstrual cycle, lordosis, and neural mechanisms governing reproductive behaviors will also be discussed, highlighting the importance of hormonal interplay in female reproductive strategies.

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.

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.
6.11 A three-chamber preference test Female tethered three chambered preference test is designed to assess male response. Other variations exist.
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.
6.15 Endocrine control of receptivity can be affected by social factors Comparison of Rhesus monkeys in different size areas.
6.19 The human menstrual cycle (Part 2) Corpus luteum development is associated with the rise in progresterone.
