Lazar Greenfield's 'Semengate' Stuns Scientific Community

Posted: 04/25/11 09:12 AM ET

Last week, New York state characterized freeze tag, Wiffle Ball, kickball and dodgeball as potentially hazardous, thereby subjecting camp providers overseeing those games to state regulation.

Out West, the NCAA is at odds with the University of North Dakota over the continued use of the nickname "the Fighting Sioux" and its accompanying logo.

But neither was the PC story of the week. That distinction belongs to a controversy surrounding a world-renowned surgeon who resigned a leadership position in the face of criticism over a one liner he delivered concerning semen.

Lazar Greenfield, M.D. is no ordinary surgeon. Until last week, he was the president-elect of the American College of Surgeons. The man is the inventor of the Greenfield Filter, a device that has saved countless lives as a means of preventing blood clots during surgery. He's a professor emeritus of surgery at the University of Michigan. He has written more than 360 scientific articles in peer-reviewed journals, 128 book chapters and two textbooks. He has served on the Editorial Board of 15 scientific journals and was also the lead editor of the Surgery News, the trade publication in which his writing initiated Semengate.

In the February issue, he penned some thoughts on Valentine's Day under the heading of "Gut Feelings." ("But Valentine's Day is about love, and if you remember a romantic gut feeling when you met your significant other, it might have a physiological basis.") Greenfield proceeded to then discuss the mating habits of fruit flies ("It has long been known that Drosophila raised on starch media are more likely to mate with other starch-raised flies"), the mating habits of the rotifer ("Biologists say that it's more advantageous for a rotifer to remain asexual and pass 100 percent of its genetic information to the next generation."). In each case, Dr. Greenfield made sure to reference to the scientific literature. Then he turned his attention to humans.

Dr. Greenfield noted the therapeutic effects of semen, citing research from the Archives of Sexual Behavior which found that female college students practicing unprotected sex were less likely to suffer from depression than those whose partners used condoms (as well as those who remained abstinent).

Presumably it was the closing line that caused the controversy: "So there's a deeper bond between men and women than St. Valentine would have suspected, and now we know there's a better gift for that day than chocolates."

The attempt at Jackie Mason-humor apparently didn't sit well in certain quarters. Dr. Greenfield resigned as editor of the Surgery News and gave up his stewardship of ACS after learning that his article had spurred threats of protests from outside women's groups.

In an interview with the Detroit Free Press last Wednesday, Dr. Greenfield explained:

The editorial was a review of what I thought was some fascinating new findings related to semen, and the way in which nature is trying to promote a stronger bond between men and women. It impressed me. It seemed as though it was a gift from nature. And so that was the reason for my lighthearted comments.

The story has been big in the scientific community, but in all that has been printed, there is one take I thought missing and noteworthy -- that of the three psychologists who authored the peer-reviewed article cited by Dr. Greenfield. So I tracked down Steven M. Platek, Rebecca L. Burch, and Gordon G. Gallup, Jr.

Speaking for the group, Dr. Steven M. Platek, Ph.D, the editor-in-chief of Frontiers in Evolutionary Neuroscience and a co-editor of Evolutionary Psychology, offered this analysis:

Frankly, we think people are over reacting to the comments made by Dr. Lazar Greenfield. There is growing evidence that human semen has the potential to produce profound effects on women. We have replicated the effects showing female college students having sex without condoms are less depressed as measured by objective scores on the Beck Depression Inventory. We've also examined the data as a function of whether the students were using hormonal contraceptives, whether they were in committed relationships, and how long these relationships have lasted. The anti-depressant properties of semen exposure do not vary as function of any of these conditions. It is not a question of whether females are sexually active, since students having sex with condoms show the same level of depression as those who are not having sex at all. We have also received numerous semen testimonials from other women who attest to the anti-depressant effects of semen exposure and these accounts often include the use of control trials (i.e., comparisons generated by switching from condoms to unprotected sex, or vice a versa).

Only 5 percent of the ejaculate is sperm. What's left is seminal plasma, which is a rich concoction of chemicals, including many that have the potential to produce mood-altering effects derived from hormones, neurotransmitters, and endorphins. There are even female sex hormones in male semen. Within a hour or two after insemination, you can detect heightened levels of many of these seminal chemicals in a woman's bloodstream.

But it is also important to acknowledge that there is a dark side to semen chemistry. The vagina is a very hostile environment for sperm. During human evolutionary history women couldn't afford to conceive as a consequence of being inseminated by just any man, and the presence of semen in the female reproductive tract often triggers an immune reaction that treats the sperm as a pathogen. Not surprisingly, semen chemistry has evolved to neutralize vaginal acidity and suppress the woman's immune system. There is even reason to believe that because of the immunosuppressant properties of semen, frequent insemination may compromise the female immune system. Because there are female as well as male sex hormones in human semen, there are other reasons to believe that additional features of semen evolved to promote the reproductive best interests of the donor. The presence of follicle stimulating hormone and leutenizing hormone in semen, implies that semen exposure has the potential to promote induced ovulation.

How can someone be asked to resign for citing a peer-reviewed paper? Dr. Greenfield was forced to resign based on politics, not evidence. His resignation is more a reflection of the feminist and anti-scientific attitudes of some self-righteous and indignant members of the American College of Surgeons. Science is based on evidence, not politics. In science knowing is always preferable to not knowing.

Or, as Dr. Greenfield told the Detroit Free Press, "My intention was to amuse rather than to offend."

Good Lord, what a ridiculous uproar over nothing. I guess we have become so politically correct that no one is safe from approbation, e.g., Anthony Weiner and no Greenfield. Geez, folks, get a life and a bit of a sense of humor. You do know that life is just too short.

Dr. Greenfield was right on target. Perhaps he is not allowed to make humorous quips about unprotected sex in this age of STDs, or perhaps it is an over-reacting, feminist-gone-wrong movement. Back in 2004, I heard Dr.Helen Fisher on NPR talking about the discovery that semen contains many powerful elements/chemicals -- such as dopamine -- that can act as a sort of tranquilizer, love-agent, and give a woman a sense of well-being. This explained a lot about the "chemistry" of love, and why some of us go through a painful withdrawal when we lose a lover. Dr. Helen Fisher was not dissed by any feminist groups. In Dr. Greenfield's case, if there was any "crime" committed, did the punishment match it?

Perhaps it was because Fisher was a woman and Greenfield was a man. There does appear to be a double standard at work here.

I don't know anything more about this than what I just read. But I detest people who attack others who dare to tell a simple truth, no matter how outside ther worldview.

A joke in poor taste isn't "a simple truth.". It's just a bad joke.
09:14 PM on 05/01/2011
"So there's a deeper bond between men and women than St. Valentine would have suspected, and now we know there's a better gift for that day than chocolates."

That's not so much a joke as a wry comment, completely supported by his research.

Your response to my comment below (which I received) was not posted. Perhaps because your comment refered to a sexual practice that was neither implied in his "joke", or discussed in the article, or examined in the study. Try re-reading the article.

I'll say it again:

PC is the art of camouflaging the truth to protect the psyches of the silly.

"The world's largest organization of surgeons has accepted the resignation"
Why didn't they reject his resignation and support him. There is no controversy.
"his article had spurred threats of protests from outside women's groups." Where? Outside the earth's orbit?

I'd much rather enjoy the good doctor's suggested Valentine's Day gift than another boring box of chocolates ... AND you get more exercise!

They don't say who the "outside women's groups" are. I belong to several "women's groups" (AAUW, NOW and groups supporting women in the sciences) and never heard of this controversy before now, and frankly if any of them has made an issue of it I'd be tempted to quit. Information about the evolution of human sexuality is always fascinating, we have a lot still to learn. The "joke" was somewhat coy and leaden but I don't see it as demeaning to women in any way. As for "promoting unprotected sex among college students", the people who read the journals he publishes in, are professionals (and grown-ups) who understand that was not his intent or that of the original authors.

One reason this country is so messed up is there has been too much attention paid to political correctness while they pick our pockets and steal our retirements.
01:24 PM on 05/01/2011
What makes this know-nothing reaction to the good doctor's "bon mot" even more unscientific is that sperm production contributes measurably to the human male's shorter life expectancy: the Valentine's gift the doctor suggests is indeed an expensive one.

I think war has more of an effect on male life expectancy than sperm production.
And the Tantra knowledge of the benfit of sperm goes back thousands of years.
04:20 PM on 05/01/2011
Depends: I've never been in a war and most likely I never will be. That's a bit of a subject change.

So in terms of MY life, sperm production - if indeed there is an effect - will have the far greater effect.

Politics...these are the same people who probably lambast certain conservatives for not accepting science. Just goes to show stupidity knows no political party.

The climate is changing; even if the two parties are at odds with science and its proof of world change.........if we can't listen to eachother how in the world can we solve a health, world, or science problem? Also, what makes it imparative to tell us women what we can or can not do with or without having an abortion? Just asking.

Everybody knows sex without mechanical barriers is better for men and women. Not a news item.

Curious to know how the transmission of semen chemicals to the bloodstream happens. I think the cervix is a seriously underrated organ.

Heck, you get nicotine from a transdermal patch. Any mucous membrane has to be a better chemical transmitter than plain old skin.
