Do human's pheromone still work on human?

We know that most creature on earth can produce pheromone to attract their mate. Some can only be produced by male or female only. Do you think that we(human) as part of nature beings can still produce ‘human pheromone’?. Will it still effective to naturally attract our mate?. Can both sexes produce this pheromone?. How can we differentiate pheromone smell from sweat smell?. Thank you.
