If I remember correctly the information I have come across, both sexes of the human animal excrete pheromone but the female senses it better than the male, who is supposedly practically oblivious to it. Humans do therefore not react to these to anything like the same degree as animals. However, I think I am right in saying there was some marginal effect on females in some scientific studies. Studies have also shown that women recognise the smell of their mate from, for example, their odour of clothes even after washing provided not too much synthetic perfume (such as in fabric softeners and even some wasing powders) is present. This recognition is however not so much connected to pheromones. The marketing of synthetic pheromones as magnets for dating purposes is, I think I am right in saying, not proved as a scientifically viable proposition.
