Orgasm-inducing mushrooms? Not quite

Claims that there is an orgasm-inducing mushroom in Hawaii may not be entirely accurate. Drawing and licensing unknown.

A few weeks ago, the social media has bombarded us with the eye-catching news that there is a mushroom in Hawaii whose smell induces spontaneous orgasms in women, but not men, who found its smell repugnant.

Except that it appears there is no such mushroom. Turns out the 14 year old paper is written by the president of a Hawaiian company that sells organic medicinal mushrooms. Not only written, but funded, as well. This is enough to damn the credibility of any study (that’s why scientists must declare competing interest when submitting a paper). But it also seems that the study has major fundamental flaws, like not having a single objective measure (of the quantity of spores, for example), is done under non-controlled environmental conditions (the participants seem to have known what was expected from them), there have been no replications, etc. Actually, it should have been suspicious to me from the start that nothing happened in the following 14 years; you would think that such claims would have been replicated, or at least the mushroom identified. But, as they say, hindsight is 20-20. Here is some nice little reporting exposing the business in Huffington Post and ScienceAlert.

I am not blaming the science media outlets on this one too much, like IFL Science or NBC affiliate, as I thought of covering this study myself, should I have been able to get my hands on the full text of the paper. In all honesty, who wouldn’t want to read that paper, especially since the abstract speculated on the mushroom’s spores having hormone-like chemicals that mimic the human neurotransmitters released during sexual encounters? But I (and others) have searched in vain for the full text and the most parsimonious explanation is that it was buried or withdrawn.

The trite but true message is: even the science media (including this one) is prone to mistakes. Interested in something? Go to the source and read the whole paper yourself, even the small print (like the one with competing interests), and only then make an opinion. That’s why I always post the links to the original article.

  1. As you and most rational, scientific minds agree, this so called study is bunk! I actually have a copy of the full paper, and if it had been turned in as a study in a college setting, it would’ve gotten an “F”!

    The fact that it was actually published in a “Journal” shows the low quality of said journal.

    Zero references, zero protocol standards, zero study details, no data on just how these so called “orgasms” were measured, and on and on, accompanied by an “ancient myth” that was obviously written by a non-Native Hawaiian and lots of specious speculation to prove a dubious point. It would be impossible to duplicate this study, since it is unclear what actually happened and how these “orgasms” were measured.

    No mention in said article about that conflict of interest with a funding pharmaceutical company, either; this was admitted to me by Holliday himself, in one of several saved emails.

    Yeah, this study out-stinks a stinkhorn!

    I am in process of writing up a full debunking of this garbage for “Mushroom, the Journal of wild Mushrooming.”

    It should be available early next year.

    Thank you for your rational analysis, an unfortunate rarity in these days of “click bait” at any price times. Sad that even some science blogs have jumped onto this salacious bandwagon.

  2. My paper debunking this ridiculous topic was just published and is now available online. Read it here:

    Shortly thereafter, and in consultation with me, Christie Wilcox published her debunking of this most specious study on her Discovery website blog:

    The truth is now out there, for all to see.
