I have read/heard different things about where a musk deer stores its perfume
Some links say it stores it in its abdomen just in front of its penis. Others say the rectum(by which I suppose they mean the backside).
A) https://en.wikipedia.org/wiki/Deer_musk "Deer musk is a substance with a persistent odor, obtained from a gland of the male musk deer situated in its back/rectal area. The substance has been extensively used as a perfume fixative, incense material, and medicine, since ancient times."
B) https://www.youtube.com/watch?v=r6CZKuSjlhI 7:40 "the fangs, but it's the other end of the deer that attracts more attention - the male's musk gland produces a scent that's irresistible to .. and perfume makers"
C) http://sandwalk.blogspot.co.uk/2009/10/are-you-sexually-attracted-to-male-musk.html Only the mature male Moschus produces musk. The substance occurs in only one location on the deer's body: on its abdomen, just in front of its penis, is a hairy pouch known as the musk gland. This sac is about the size of a golf ball. It is composed of several layers of skin, with two openings immediately above the animal's urethra.
Quite a few links agree with 'C', that it's in the abdomen near the penis. Are wikipedia and national geographic wrong for putting the musk pod in the backside?
