Animals Male and female Fitch ferrets, aged 12-19 wk, were purchased from Marshall Farms (North Rose, NY) and were housed individually in modified rabbit cages (24’’ X 12’’ X 18’’) on a long-day (16L:8D) photoperiod. All ferrets were fed a diet of moistened Purina ferret chow and were given water ad libitum. Ferrets were gonadectomized […]

We previously compared neuronal Fos responses to pheromones in gonadally intact male and female ferrets in breeding condition. Rigorous sex comparisons of neuroendocrine and behavioral functions are best carried out in gonadectomized subjects that receive either no replacement sex steroids or the same activational hormone treatment (reviewed in ). Therefore, in experiment 1 we asked […]

The relatively small size of the ferret’s VNO-AOB system raises the question of whether it is activated by pheromones. When gonadally intact, breeding male and female ferrets were either allowed to mate or exposed to odors from breeding animals of the opposite sex, significant increases in neuronal Fos-IR were seen in the granule cell layer […]

In the male hamster, pheromonal and hormonal cues must be integrated in the MA and/or BNST in order for mating to occur. The relevant pheromonal signals are usually detected by the VNO, although the main olfactory epithelium-main olfactory bulb (MOE-MOB) olfactory projection to the hypothalamus may also contribute to sexual arousal and performance. flovent inhaler

Chemosensory cues (pheromones) derived from urine or from anal and genital sebaceous gland secretions contribute to heterosexual partner selection and subsequent reproductive success in many vertebrate species. In rodents, pheromones are often detected by sensory neurons located in the vomeronasal organ (VNO), which send their axons to the accessory olfactory bulb (AOB) (reviewed in ). […]
