Perfume or Animal what?!?

One of the realities of travel is learning about different aspects of how humanity benefits from nature. Around the world the same how there are delicacies with food there are also delicacies with smell. One of these delicacies is collecting the musk that comes from various animals.

The musk is taken from the glands of the male deer, civet cats, and also the regurgitation of the whale (ambergris). The musk along with sandalwood are some of the common bases of men's cologne. It's known that when it's the mating season the men give off secretions from its sexual glands which attract the female deer. Many people say what works in the animal kingdom works for us humans too. Yay or nay? Here in the picture shown is Deer Musk with the sex gland still inside at a cologne shop in Saudi Arabia.
