Penile Cancer Linked to Sex with Animals

Penile Cancer Linked to Sex with Animals

Bestiality and cancer link

While the thought of bestiality may make some people feel sick to their stomach, for others it can mean death. That is, according to a study posted in the October 24 online edition of the Journal of Sexual Medicine, men who have had sex with animals are twice as likely to contract penis cancer as those who didn't.

The study examined just south of 500 men, ranging from ages 18 to up to 80 years of age. 45 men out of the 118 penile cancer patients reported having sex with animals. Twenty-one percent of the men had sex with animals for more than five years, while 59 percent had sex with animals for one to five years. What's more, over 30 percent of the subjects had sex with animals in groups.

The researchers found no correlation between penile cancer and the type or number of animals used (i.e. chickens, pigs, mares, or other animals). Because even tiny injuries to the penis increases the risk factor of penile cancer development, trauma to the penis that occurs along with sex with animals may explain how penile cancers develops in these people.

According to the National Center for Biotechnology Information, penile cancer metastasizes (spreads to other parts of the body) early on in the disease. The five-year survival rate for cancer of the penis is 65 percent.

Laws that prohibit sexual contact between animals and humans has been enacted in over thirty states in the United States.

Along with other reasons, the higher risk of penile cancer should discourage sex with animals, researchers note.
