Male Goat's 'Goaty' Pheromone Puts Females in the Mood	There is more to that characteristic goaty odor of male goats than one may think (or smell). It turns out a male goat's scent is powerful enough to get female goats in the mood.	New research has identified a pheromone in the hair of male goats that activates a hormone in female goats called gonadotropin-releasing hormone which stimulates their reproductive systems. The pheromone is called 4-ethyloctanal.	In 4-ethyloctanal we identified a novel chemical that had never been demonstrated in nature before. This was our first surprise study author Yukari Takeuchi of the University of Tokyo said in a statement.    	The researchers also found that when 4-ethyloctanal reacts with oxygen it converts to a related compound called 4-ethyloctanoic acid which is the main ingredient of the goaty odor that plays a crucial role in attracting females to males.

The researchers think this may be a clever reproductive strategy of the male goat he said.	Researchers knew for a long time that in sheep and goats the males somehow stimulated the release of reproductive hormones in females but now the new study has identified the actual compound at work said John J. McGlone a Texas Tech University professor who was not involved in the study.	I think it is pretty convincing that they have identified the compound McGlone said.	There are thousands of insect pheromones and there are probably at least hundreds if not thousands of mammalian pheromones but only 15 to 20 mammalian pheromones have been identified he said.	Identifying them is tough however thanks to the use of modern technology it is becoming easier McGlone told Live Science.	The research may have implications for species other than goats he said. When there is a pheromone in one species what we are learning is that it often has effects on other species.	For instance there is a pig pheromone that stops dogs from barking McGlone said.	The new goat pheromone could even have an effect on humans he said but he noted the olfactory systems of different species can respond differently to the same pheromone.	The new study illustrates fundamental differences between the ways in which humans and animals interact with their environments.	Where we see the world primarily through sight and sound and then touch and a little bit of smell they see their world primarily through their sense of smell McGlone said. They are sensing things in the environment that we can't sense.	Follow Agata Blaszczak-Boxe on  Twitter  .  Follow  Live Science @livescience  Facebook  &  Google+. Original article on  Live Science.
