Sex with Animals (SWA): Behavioral Characteristics and Possible Association with Penile Cancer. A Multicenter Study

“Introduction.  Zoophilia has been known for a long time but, underreported in the medical literature, is likely a risk factor for human urological diseases. Aim.  To investigate the behavioral characteristics of sex with animals (SWA) and its associations with penile cancer (PC) in a case-control study. Methods.  A questionnaire about personal and sexual habits was completed in interviews of 118 PC patients and 374 controls (healthy men) recruited between 2009 and 2010 from 16 urology and oncology centers. Main Outcome Measures.  SWA rates, geographic distribution, duration, frequency, animals involved, and behavioral habits were investigated and used to estimate the odds of SWA as a PC risk factor. Results.  SWA was reported by 171 (34.8%) subjects, 44.9% of PC patients and 31.6% of controls (P < 0.008). The mean ages at first and last SWA episode were 13.5 years (standard deviation [SD] 4.4 years) and 17.1 years (SD 5.3 years), respectively. Subjects who reported SWA also reported more venereal diseases (P < 0.001) and sex with prostitutes (P < 0.001), and were more likely to have had more than 10 lifetime sexual partners (P < 0.001) than those who did not report SWA. SWA with a group of men was reported by 29.8% of subjects and SWA alone was reported by 70.2%. Several animals were used by 62% of subjects, and 38% always used the same animal. The frequency of SWA included single (14%), weekly or more (39.5%), and monthly episodes (15%). Univariate analysis identified phimosis, penile premalignancies, smoking, nonwhite race, sex with prostitutes, and SWA as PC risk factors. Phimosis, premalignant lesions, smoking, and SWA remained as risk factors in multivariate analysis. However, SWA did not impact the clinicopathological outcomes of PC. Conclusion.  SWA is a risk factor for PC and may be associated with venereal diseases. New studies are required in other populations to test other possible nosological links with SWA.”

WTF is NCBI ROFL? Read our FAQ!

  • Zdfs

    SWA was reported by 171 (34.8%) subjects

    Oh, my god.

  • Winberly

    34.8% DOES seem like a really high percentage for this. I expected something like 1%….

    WTF???!!!!

    I’ve become somewhat disenchanted with NCBI ROFL. So many of these papers simply aren’t funny, or are so badly designed that the results are essentially meaningless. Here we have research that no one gives a crap about, primarily because as a cause of cancer it contributes to approximately 0.0% of cancer cases found in the general population.

    What’s more, the data is based on a questionnaire? With no postulated mechanism? And a weak-ass “more research is required” conclusion? Please. There’s a reason that statement was banned from all papers submitted to the BMJ: it’s an intellectually dishonest non-statement that contributes no meaningful information.

    What a waste of time and money. I’m talking about you, Discover Magazine. Whoever picks this tripe is really scraping the bottom of the barrel. There are plenty of real lol-worthy studies that also actually contribute meaningful information to science. Let’s try harder, shall we?

    I’m glad to see that there is science out there thinking about taboo topics. Just because something is taboo does not mean it never happens. I’m part of the 34.8%

    “BEAUTY AND BEAST” is the culprit, which should be banned.
