Sex With Animals: Results of a new survey

The new Brazilian report about sex with animals has finally been published online.

Sex with Animals (SWA): Behavioral Characteristics and Possible Association with Penile Cancer. A Multicenter Study,” Stênio de Cássio Zequi [pictured here], et al., Journal of Sexual Medicine, published online October 2011. (Thanks to Richard Wassersug for bringing this to our attention.) The authors, at various institutions in Brazil, report:

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….
SWA was practiced with the same animal by 38.0% of SWA practitioners, with similar rates reported by PC patients and controls (34% vs. 39.8%, respectively; P = 0.638). The number of animals involved per individual ranged from 1 to 7. The animal types most often cited were mares (N = 80), followed by donkeys (N = 73), mules (N = 57), goats (N = 54), chickens (N = 27), calves (N = 18), cows (N = 13), dogs (N = 10), sheep (N = 10), pigs (N = 6), and other species (N = 3). Chickens were more frequently involved in the south and southeast of the country, with only three reports in the northeast, where donkeys dominated the reports. Higher SWA rates were found in the northeast (45%), with the highest rates in Piauí and Maranhão.

BONUS: These findings seem not inconsistent with the Canadian report published two years ago (and described here recently) about a man and his mare wives.
