As far as I know, the only ever TED talk devoted to the subject of pheromones. Presented back in 2014 by Tristram Wyatt, who is the respected senior researcher in the department of zoology at the University of Oxford. As Mr Wyatt explains, although there is still a lack of definitive scientific proof that pheromones play a role in human sexual behavior, in theory they should, just as they do in virtually every other sexually reproducing animal on Earth (including primates).
Wyatt proposes that we may be looking for evidence in the wrong way, and that self-reporting surveys and the like, which make up the bulk of present day efforts to prove the efficacy of specific pheromone candidates, might be very unreliable. He claims that we need to be observing humans as we would any other animal, and interestingly makes the suggestion that one of the most promising of possible pheromone leads is a a nipple secretion from the areola glands produced by all lactating mothers. Apparently, this secretion stimulates suckling by any baby, not just their own. The similarities with oxytocin are obvious.
Tristram Wyatt expounded his thesis in the form of an academic paper a year after his TED talk, and it can be viewed here.
