Do human beings have pheromone receptors?
From what I have gathered, I would think that humans do have receptors that are able to detect pheromones.

For example, some studies that have indicated human responses to pheromones.  Of these pheromone responses, some have been traced to the olfactory mucosa and olfactory epithelium.

The trace amine-associated receptors (TAAR) for which humans have 7 genes (TAAR1, TAAR2, TAAR3, TAAR5, TAAR6, TAAR8, TAAR9) and 2 pseudogenes (TAAR4P, TAAR7P) are found in the olfactory epithelium whereas androstadienone receptors are found in the olfactory mucosa.  As suggested by the anatomical location, these receptors interact with the human sense of smell and the olfactory system
