At the endocrinological level, the VNO mediates the surge of luteinizing hormone and testosterone in males after exposure to females. This surge does not occur if a male with deafiferentiated VNO is exposed to an anesthetized female or her urine (Wysocki etal., 1983). But VNO-deafferentiated males will show a surge in luteinizing hormone in response to awake females (Coquelin etal., 1984). In female mice, stimulation of the VNO by male urinary cues activates the limbic system (discussed in Ch. 8). The roles of the VNO in the behavior of some rodents are listed in Table 5.3.

FIGURE 8.4 The Bronson model of priming pheromone actions in rodents. Chemical signaling between males and females constitutes a feedback mechanism that results in accelerated maturation and reproduction. This, in turn, permits the mice to adjust their reproduction and population size quickly to respond to environmental conditions such as sudden food abundance at harvest time.

In the case of the Ellegaard virgin-mated females, the gilts are given luteinizing hormone before mating. 

As well as the sex hormones already mentioned (see above), many other hormones seem to affect the metabolism of foreign compounds and therefore may have effects on toxicity. A number of pituitary hormones may directly, as well as indirectly, affect metabolism, for example, growth hormone, follicle-stimulating hormone, adrenocorticotrophic hormone, luteinizing hormone, and prolactin. Thus, hypophysectomy in male rats results in a general decrease in metabolism, but the effects of some of the individual hormones may depend on the sex of the animal and the particular enzyme or metabolic pathway. For example, adrenocorticotrophic hormone (ACTH) administration decreases oxidative metabolism in males but increases N-demethylation in female rats. Removal of the adrenal gland reduces metabolism, such as ethylmorphine demethylation and aniline 4-hydroxylation, and this can...
