Bestiality linked to penile cancer

by Deborah Braconnier report

(Medical Xpress) -- While there are already laws against such activity in many areas, a new study finds yet another reason to avoid bestiality, or sex with animals. The new study, published in the Journal of Sexual Medicine, finds a link between bestiality and penile cancer.

The study, led by urologist Stenio de Cassio Zequi in San Paulo, looked at 492 men from rural Brazil. The men participating ranged in age from 18 to 80. Of the 492 men, 118 had been diagnosed with penile cancer.

Of the 188 men with penile cancer, 45 percent had sexual relations with compared with 32 percent of the healthy males. Of those men who had sexual relations with animals, 59 percent reported having sex with animals for one to five years and 21 percent had been doing it for more than five years.

Sexual interaction occurred as often as daily and included animals such as horses, cows, pigs and chickens.

Researchers believe that sexual interaction between humans and animals may produce micro-traumas in the penis such as scratches and cuts. They theorize that animal secretions may be toxic to humans and that some unrecognized microorganism may be responsible for the cause of penile cancer.

Circumcision seems to also play a role in the development of penile cancer, with males who have been circumcised seeing penile near zero. Researchers believe that uncircumcised men may be more at risk of developing micro-traumas. The majority of the men in the study was uncircumcised and may have contributed to the rates of penile cancer.

Penile cancer accounts for as much as 10 percent of male cancer in Africa, Asia and South America. It is however rare in the United States. In the U.S., thirty states have laws connected to animal cruelty legislation prohibiting bestiality.

While bestiality has been a part of history and is described in theater, jokes, folk music and oral traditions, it is not something that has been studied and represented in scientific research. This is the first study to link the practice to genital cancers.

One incredibly surprising result of this study:

That the researches were able to convince 85 men to declare:
Sexual interaction occurred as often as daily and included animals such as horses, cows, pigs and chickens.

Is it creditable that one third of healthy men in rural Brazil engage in bestiality? I do not buy this.

A more plausible explanation of the findings is that there is a risk factor X that leads both to penile cancer and having nonstandard sexual experiences which include those with animals. X could be an urge for unusual sexual experiences in general. This could result in such men putting themselves at risk of exposing their penis in general to cancer causing injuries/chemicals hence great risk in them of penile cancer.

So are you saying babies should be circumcised to reduce their risk of getting penile cancer from having sex with animals? (No claim about circumcision is too silly for someone to make.)

The circumcision-penile-cancer connection has long been debunked. Penile cancer is rarer in non-circumcising Denmark than the US.

This article bears a striking resemblance to the Mayo Clinic's
list, with its use of "may" with benefits. Now, we can add one.
Circumcision may have various health benefits, including:
Easier hygiene. Circumcision makes it easier to wash the penis although washing beneath the foreskin of an uncircumcised penis isn't generally difficult.
Decreased risk of urinary tract infections. The overall risk of urinary tract infections in males is low, but these infections may be more common in uncircumcised males. Severe infections early in life can lead to kidney problems later on.
Prevention of penile problems. Occasionally, the foreskin on an uncircumcised penis may be difficult or impossible to retract (phimosis). This can also lead to inflammation of the foreskin or head of the penis.
Decreased risk of penile cancer. Although cancer of the penis is rare, it's less common in circumcised men. In addition, cervical cancer is less common in the female sexual partners of circumcised

Or alternatively, stop mutilating children for religious reasons, wash your cocks and don't f**k chickens!

Which reminds me -- and now I'm going to get way off-topic -- have you ever seen one of the documentaries on people who are in love with an animal, or a car? Not just sex you understand, but actually claim to be "in love". Pretty wild.

I don't buy this, as a full time practicing zoosexual for more than 40 years I have never once contracted a thing from an animal, not even a bladder infection. The animals cited in the articles on this, particularly- mares, cows, pigs, chickens and donkeys- these animals are quite dirty, with feces commonly coming in contact with the vulva, underside of the tail and back legs and the fact chicken's cloaca is ALSO used for excretory wastes there would be considerable contamination with ecoli, bacteria and other pathogens and bacteria that is unhealthy in any situation.

Dogs on the other hand in the USA, when kept indoors, vaccinated, groomed, kept free of parasites, wormed and in good health are quite CLEAN animals.

Avoiding any anal contact is ALWAYS a good idea regardless of species or degree of cleanliness, but as I indicated, 40 years heavy experience with many dogs and not contracting even one bladder infection speaks for itself.

I personally know many others, and never met any who indicated they ever had any illnesses or problems from their activities

Of particular note is circumcized men had a near ZERO cancer rate, it is also RARE in the USA.
The fact that most of the cases cited in the articles were men who were not only uncut, but ALSO frequented prostitutes, the study was only 492 men from rural Brazil too, I would surmise uncut men who do prostitutes AND animals likely dont' wash very often too and all put together it would explain the cancers in these men

I dont buy it either, and a study of only 400 men, all of whom lived in rural Brazil is hardly all that valid. SMOKING and other factors including frequenting prostitutes were mentioned, and we all know hookers carry MANY communicable diseases that are ALWAYS transmissible human to human during sex, there's more than 25 STD's alone while NONE of those human STD's are transmissible or contracted by animals such as dogs,
horses etc. SOME might be in primates, but obviously primates are closely related to humans and contract many of the same diseases dogs dont such as influenza, common colds, HIV, VD etc.

Hey, now, don't be picking on the hookers. It was clearly those chickens!
