The cause of dysosmia still remains a theory. It is typically considered a neurological disorder and clinical associations with the disorder have been made. [3]
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
About half of the women in a recent study on IUD placement and pain reported “intense” pain at placement, and another 47 percent reported light or moderate pain. Only 2.5 percent reported no pain.
