Proceptivity

Loss of proceptive behaviour also follows VN-x in female rats, in which the receptive posture (lordosis) is almost abolished (Saito and Moltz, 1986). Estrous cycles with receptivity were still maintained, since males given extended access to VN-x females inseminate them successfully.

In rodents the most commonly studied female sexual behavior is the lordosis posture, in which the female remains immobile and concavely arches her back. Lordosis, usually in response to mounting, has been used as an index of female sexual receptivity. In addition, a variety of other measures such as elective proximity to a male have been used to index sexual proceptivity. Studies of these and related behaviors have shown that in rats ovarian secretions are essential for the expression of lordosis and can increase the expression of a variety of sociosexual behaviors (Pfaff, et al., 1994). Surgical removal of the ovary (ovariectomy) eliminates female sexual behavior in most rodents, and treatments with estrogen and progesterone can produce levels of sexual receptivity that closely resemble those seen in a gonadally-intact estrous female. 

Hormonal control of mating behaviour is well documented in animals. In rats, estrogen and, to a lesser extent, progesterone control lordosis behaviour via the central nervous system (CNS). In female non-human primates, attractiveness and proceptivity change during the menstrual cycle or as a result of sex steroid administration. The effects of hormones on receptivity are unclear. It is assumed that steroid hormones influence behaviour in humans as they do in animals however, it is difficult to differentiate the effects of social and other environmental factors from the effects of sex steroids on mating behaviour in humans.

PROTEIN CONTENT OF MALE DIET DOES NOT INFLUENCE PROCEPTIVE OR RECEPTIVE BEHAVIOR IN FEMALE MEADOW VOLES, MICROTUS PENNSYLVANICUS... 

Sexual behavior is comprised of the three components attractivity, proceptivity, and receptivity. Previous work has shown that a meadow vole s odor attractivity to the opposite sex is positively correlated with the amount of protein in the diet that it consumed. We determined whether protein content of a male vole s diet (high, medium, or low) affected proceptivity and receptivity of a female vole. The protein content of the diet of male voles did not affect female proceptivity or receptivity. These findings suggest that the protein content of a male s diet may affect a female s initial interest in a male but not whether she will mate with him. 

Protein content of the diet of male meadow voles had no effect on female proceptivity and receptivity. In experiment 1, female voles spent similar amounts of time self-grooming to bedding scented by males fed HP, MP, and LP diets. In experiment 2, protein content of the diet of males did not affect the sexual behavior of females. Specifically, the female s willingness to copulate and the PIL did not vary for males fed diets with different protein contents. The data do not support the hypothesis that the protein content of a male s diet affects the proceptive and receptive behaviors displayed by female conspecifics towards them. These results are not consistent with the...
