Sex And Fruit Flies


These cute bugs aren’t fruit flies. Fruit flies don’t do photogenic love on daisy petals.

This little guy, indeed, is a fruit fly. Let’s call him Fred. He resides at the laboratory of Ulrike Heberlein at the University of California, San Francisco.

Does Fred appear drunk to you? Hard to say, because we don’t know (at least I cannot say) whether  Fred is postcoitally happy or pissed off, having been rejected by “a girl”. If Fred is a snubbed sad sack, then, indeed, he might be drunk. The research  suggests that fruit-fly-lads just like Fred drink significantly more alcohol than those that have plenty of great sex. What the scientists have done that pushed Fred to become a low-life drunk?

In Sex-starved fruit flies turn to drink, researchers tell it all. It has to do with the level of neuropeptide F (NPF) chemical: alcohol stimulates Fred’s brain to compensate for lack of sex by giving him “high” in a way good fruit-fly orgasm would.

Sexual frustration is bad for your health, particularly if you are Fred. Sex-starved fruit flies live shorter, more stressful lives. Scientists found that male flies who were stimulated to mate but prevented from doing so, had their lives cut short by up to 40%.

What this new finding tells Fred?  Chin up, Fred! If she said no, don’t sulk. Go and get drunk.

Interesting.  Sex topics often are.

Let’s leave Fred to live long and happy life as a drunk for now  and turn to Jack an Jill. They are humans. For the sake of this post, they are British. If what is true for Fred is true for Jack and Jill, then “statistical” British Jack and Jill are in big trouble. Not so much from sexual frustration or rejection but of indifference to sex. Whatever happened to Jack and Jill?


Modern life is “turning people off sex“, that’s what.

“People are worried about their jobs, worried about money. They are not in the mood for sex. 
…But we also think modern technologies are behind the trend too. People have tablets and smartphones and they are taking them into the bedroom, using Twitter and Facebook, answering emails.” (Dr Cath Mercer, from University College London)

Get yourself a toddy, Jack and Jill.

Why have young people in Japan stopped having sex?

Japanese too? What’s going on in the world!?   The title of this article in the Guardian says it all. The bi-line — What happens to a country when its young people stop having sex? Japan is finding out —  is even more telling. Japanese

 45% of Japanese women aged 16-24 are ‘not interested in or despise sexual contact’. More than a quarter of men feel the same way.  …Millions aren’t even dating, and increasing numbers can’t be bothered with sex. For their government, “celibacy syndrome” is part of a looming national catastrophe. Japan already has one of the world’s lowest birth rates. (From the article.)

That’s sekkusu shinai shokogun for you. Japanese Jacks and Jills suffer from  “celibacy syndrome”, losing interest in conventional relationships.

Say, how about them Russian folks? How do Vanya and Masha fare, compared to Jacks and Jills elsewhere?


Low standard of living , the total criminalization of life in the country , the destruction of the public health system, threat of AIDS and sexually transmitted infections, …  threat of death associated with such cultural and historical dispositions such as fatalism , social and masochistic helplessness are recognized as factors, affecting individual aspects of modern sexual culture in contemporary Russian society… (fromFactors of sexual culture in modern Russia: sociological analysis” by Tatiana Pichugina.)

Oy! Let’s make us a stiff drink in a really tall glass. Wanna get drunk, Fred?

  1. Life is hard for all species, big and smaller, whether you’re locked in your cubicle, or damped in a lab jar. Everyone tries to cope with it in his/her own way, British, Japanese, sexually distressed fruit flies. Some drown their distress in alcohol, others abstain.
