The vomeronasal organ VNO is important for activating accessory olfactory pathways that are involved in sexually dimorphic mating behavior. The VNO of male garter snakes is critically important for detection of, and response to, female sex pheromones. In the present study, under voltage-clamp conditions, male snake VNO neurons were stimulated with female sexual attractiveness pheromone. The amplitude of the inward current was dose dependent, and the relationship could be fitted by the Hill equation.
Snakes and female sexuality

With their sinuous bodies, sharp fangs and, sometimes, potent venom, snakes have long struck fear into the hearts of humans and our primate ancestors. But when it comes to mating, do these ancient reptiles also have a softer side? More than 3, species of snakes exist today, living on all continents except Antarctica, as well as many islands across the globe. Though snakes garner much media and research attention, the reproductive strategies of many species are still shrouded in mystery. Unlike most other snakes, the mating behaviors of garter snakes have been extensively studied. Female garter snakes will emerge from their winter hibernation — technically called "brumation," a hibernation-like state that cold-blooded animals go through during chilly months — a few days after males do.
Snake sex is every bit as peculiar as you would expect
Mating season is just around the corner for many animals that call the Arb home. For our native garter snake population, mating is quite the sight… and smell. Garter snakes, which are non-venomous, communicate through the release of pheromones. Pheromones are chemical cues that trigger a social response from others in the population; in this case, male and female snakes send out very distinct scents to signal mating season.
