Circumcision Does Not Prevent HPV Infection, RCT Data 'Inflated,' Study Finds

Researchers at the University of Washington find no relation between circumcision status and HPV infections, and that high HPV infection sites are ignored in previous studies, leading to false claims of the protection benefits of circumcision.

(NEW YORK, NY) — An original study at the University of Washington has found that male circumcision has no effect on human papillomavirus (HPV) infection rates. These results counter the widely publicized claims that intact males were more than 1.5 times likely to acquire HPV.

HPV is a sexually-transmitted virus known to cause cervical cancer in women. While HPV infections in women have been widely studied, HPV infections in men is an area lacking in research.

This University of Washington study tested for HPV infection at the head of the penis (or glans), on the shaft/scrotum skin, and in urine samples. Researchers found that the shaft/scrotum skin were the most likely sites of HPV infection in circumcised males, with a higher percentage of infections at these sites in circumcised males as compared to intact males.

Since shaft and scrotum skin together comprise the vast majority of the surface area of the penis in circumcised males, and are the most likely sites for HPV infection in circumcised males, any research done on circumcision status and HPV infection must necessarily include these sites.

However, most randomly-controlled trials (RCTs) only include testing of the head of the penis (or glans) for HPV infection. The widely-publicized RCT in Rakai, Uganda is one notable example. By not including all sites of infection, and in particular, by ignoring sites that have the highest chance of infection in circumcised males, researchers are producing false claims of protection.

Furthermore, the researchers of this U. of Wash. study note that most RCTs fail to account for the recovery period in circumcised participants who have to wait until their wounds heal, allowing time for the intact males to get infected. This  leads to further inflated claims of a protection benefit from circumcision.

In contrast to recent tightly-controlled trials such as the one in Rakai, Uganda, many surveys show that circumcised men have higher HPV infection rates. A United States national health survey on HPV infections found that the "percentage of circumcised men reporting a diagnosis of genital warts [caused by HPV infections] was significantly higher than uncircumcised men."


I can’t believe this. A great testimony that i must share to all patient of [HPV] in the world. i never believed that their could be any complete cure for HUMAN PAPILLOMA VIRUS or any cure for HSV, Mrs EDITH introduce me to Dr Ejeke ogumen a herbal doctor who lives in Africa who brought him back to life again. so i had to try it too and you can,t believe that in just few weeks i started using the herbal medicine he sent to me i was perfectly OK and . Right now i can tell you that few months now i have not had any symptoms of HPV and i have just went for text last week and the doctor confirmed that there is no trace of any HPV in my body system. Glory be to God for leading me to this genuine Dr Ejeke ogumen.

My advice to you all who thinks that their is no cure for HPV that is Not true ,just contact him and get cure from Dr Ejeke ogumen via his email and you will be free and free forever, Try it and you will not regret it because it truly works. One thing i have come to realize is that you never know how true it is until you try...

When I started PurseBlog coach outlet over 11 years ago, it was because I coach factory outlet online absolutely loved bags. I remember how excited I got when I'd get to the coach outlet store online mall and go into the coach store or department store to look at bags. I'd tear out ads from coach outlet online magazines with photos of bags from upcoming collections that I was coach factory outlet yearning for.

After 11 coach outlet store online years of talking about bags, I've found coach outlet online majority of brands wax and wane with popularity, while one coach factory outlet online year is all about designer X and the coach factory outlet following about a chi flat iron different ralph lauren outlet designer. I spend every day looking at bags and while I still truly am a bag girl, I find it harder to coach factory online narrow in on designs that have my heart going pitter-patter. Part of this is abercrombie and fitch because I now have a substantial collection coach outlet online and the other part is valentino shoes because I see so many bags in person and online daily. But because of this, when I see a bag I coach outlet absolutely love, I know it right away. It's that feeling I get deep down in my core that got me started in all of this and has me continuing coach outlet PurseBlog after all of these years.

I've had the Marc Jacobs outlet intense ‘I love this bag' feeling coach outlet online happen to me a few times with different colors of this Chloé Hudson Small coach outlet Shoulder Bag for a while now.

Amanda and I feel similarly that when it comes to our realm that coach factory outlet store bags are top of the game right now (Amanda shared why she thinks coach outlet Chloé is making the best bags right now). Sure other brands have coach outlet beautiful bags, but coach factory outlet is a coach outlet store online brand I continue to be drawn to.

The coach factory Hudson is now a staple for coach factory online the brand but I'm all kinds of obsessed with this suede version coach outlet that is exclusive to Neiman coach factory outlet Marcus. The coach outlet deep purple wine hue is dreamy and perfect for the upcoming fall season. I love the coach factory online smaller size of this bag coach Purses and have tried it in store to know that it will coach outlet online store carry plenty while not being too large.

Overall, this michael kors outlet online bag is just michael kors outlet online good, pretty and I've added it to my fall wardrobe true religion outlet. There are a few other hues (you can shop a good assortment of Chloé bags at Neiman Marcus), but this new coach outlet color in suede has shot up to the top of michael kors outlet my list as a favorite. It's exclusive to Neiman Marcus so if I end up buying it, we can be coach outlet bag twins. Shop it via michael kors outlet for $2,090.

coach is America's biggest homegrown michael kors outlet online accessories brand, not to mention arguably the world's most michael kors outlet online important contemporary handbag brand, so we always pay michael kors outlet attention when there's a new coach collection to see. That's especially michael kors outlet online true since creative michael kors outlet online director Stuart Vevers launched coach 1941, the company's more fashion-forward michael kors outlet and coach outlet online luxurious michael kors offshoot, and the coach 1941 Fall 2016 michael kors outlet collection, which coach outlet just michael kors outlet launched on, demonstrates exactly why.

All of that is balanced with more whimsical notes, though, including a very cute illustrated dinosaur named Rexy.

I am surprised that no one ever raises the question of the appropriateness to perform surgery on one patient (without their consent) in order to reduce the risk of disease in someone else. This seems to violate medical ethics.
