> Circumcision would reduce Hiv infections

The circumcised men have less chanceà to be infected by the virus that causes Aids. The reason " due to explanations of biological and non-sexual behaviors less risky.

by the time Aids appeared in Africa, scientists knew that he was a più common in the east and in the south of the Continent rather than to the west. Initially, pensò that the cause was the different sexual behavior, but some scientists theorized that the reason could be circumcision (più common in west Africa) and the fact that the foreskin were more sensitive to the virus to other parts of the penis. The latest research confirms this hypothesis.

researchers from The Translational Genomics Research Institute in Arizona and George Washington University in a study published in the journal open-access, the American Society for Microbiology, they claim now that the circumcised men have less chanceà to be infected with the Hiv Virus, a protective effect may be due to the alteration of the microbiome of the penis observed in those who è subjected to surgical practice.

it must Be said to our readers what is meant by the gut microbiota: is the set of the genetic and environmental interactions of anyà micro-organisms of an environment is defined.

The protective effect would be due to changes on the ecosystem  of the penis following the circumcision that would, in particular, a strong reduction of the bacterial species that are anaerobic, lowering così, in some way, the probability; of the contagion.

In circumcised men the chanceà of Hiv infection was reduced by 50-60% compared to those not circumcised, in agreement to previous studies conducted in Africa, and the effect of the protection that had the subject of the circumcision extended not only to other viral infections such as papilloma virus or the Herpes virus, but also to the partners who had a rate of sexually transmitted infections più below.

What was the mechanism through which circumcision conferred protection from infection was not forò clear.

Thereò that so far was not clear was what was the mechanism through which circumcision conferred protection from infection.

The american researchers have used specimens obtained from genital swabs taken in a study carried out in Uganda.

the difference in The microbiome between circumcised and was not dramatic, and in a distance of a year, the subject of the circumcision had a bacterial più homogeneous and lower than in the control group.

it Continues to remain dark what is the role dl microbiome and how it is possible that a reduction might give more protection.

These results are, however, important becauseé a confirmation could help develop new therapies to eliminate specifically these bacteria without having to resort to circumcision.
