This week, in a <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/dx.doi.org\/10.1098\/rspb.2009.1720\">paper<\/a> (in press) in the <em>Proceedings of the Royal Society B<\/em>, the study of goofy genitalia follows fruit flies.<\/p><p>The male fruit fly has a penis that resembles a medieval weapon, dotted with hooks and spines. Are those barbs there to remove rival sperm, or pierce the female&rsquo;s genital tract to allow sperm a shortcut, or something else? There was one way to find out: lasers.<\/p><p><span><\/span>Scientists used lasers to shave the extra equipment off male fruit flies&rsquo; penises and set them free to try to mate. And, as it turned out, the hooks and spines simply help a male hang onto a female for the whole 10 minutes it take them to mate; without them, he didn&rsquo;t do so well. <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/scienceblogs.com\/notrocketscience\/2010\/01\/study_reveals_sexual_tactics_of_male_flies_by_shaving_their.php\">From &ldquo;Not Exactly Rocket Science&rdquo;<\/a>:<\/p><p><span>They found that a partial shave did nothing, but the full treatment significantly reduced the odds of the males mating with females. With the spines, they were virtually guaranteed to mate if a female was around; without them, their chances fell to around 20%. It wasn&rsquo;t for lack of trying either &ndash; all of the shorn males tried to woo a female and almost all tried to mate. They simply failed. They did all the right things &ndash; mounting, placing their genitals in the right place &ndash; but it was for nought. And if the spineless males were placed in direct competition with a normal one over a female, they almost always lost. <\/span><\/p><p>Related Content:<br>Discoblog: <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/blogs.discovermagazine.com\/discoblog\/2009\/02\/25\/the-strange-violent-sex-lives-of-fruit-flies-and-beetles\/\">The Strange, Violent Sex Lives of Fruit Flies &amp; Beeltes<\/a><br>80beats: <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/blogs.discovermagazine.com\/80beats\/2009\/10\/16\/meet-the-sexually-irresistible-fruit-fly\/\">Meet the Sexually Irresistible Fruit Fly<\/a><br>The Loom: <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/blogs.discovermagazine.com\/loom\/2009\/12\/22\/kinkiness-beyond-kinky\/\">Kinkiness Beyond Kinky<\/a><\/p><p><em>Image: <a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/commons.wikimedia.org\/wiki\/Image:Drosophila_melanogaster_-_side_%28aka%29.jpg\">Wikimedia Commons \/ Andr&eacute; Karwath<\/a><\/em><\/p><p><a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/feedads.g.doubleclick.net\/~a\/Z2LvGCikhZ95nUl7G3nzxnGNxCA\/0\/da\"><img decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/c0bc8_di\" border=\"0\" style=\"padding-left:10px; padding-right: 10px;\"><\/a><br><a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/feedads.g.doubleclick.net\/~a\/Z2LvGCikhZ95nUl7G3nzxnGNxCA\/1\/da\"><img decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/c0bc8_di\" border=\"0\" style=\"padding-left:10px; padding-right: 10px;\"><\/a><\/p><p><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/c0bc8_5FY_Y3B1WZw\" height=\"1\" width=\"1\" style=\"padding-left:10px; padding-right: 10px;\"><\/p>","protected":false},"excerpt":{"rendered":"<p>When it comes to peculiar penises, there&rsquo;s no shortage in the animal kingdom.
