According to a research, lubricants might make anal sex a relaxing experience, but they might also increase the possibility of widening sexually transmitted contagions, together with HIV.

Two studies that were submitted at the International Microbicides Conference in Pittsburgh suggested that the risk of developing HIV through insecure anal sex is at least 20 times higher, compared to unguarded vaginal sex and boosts, if other contagions already exist in the rectal lining.

In one study, entailing roughly 900 men and females in Baltimore and Los Angeles, the canvassers discovered that those who made use of lubricants were three times more prone to have rectal sexually transmitted infections (STIs).

Another study, which subjected famous over-the-counter and mail-order lubricants to thorough laboratory tests, found that a lot of the products were lethal to cells and rectal tissue.

If in human beings, these products have similar outcome, the cells may be regarded as more susceptible objects for HIV infection than they already are.

Microbicides substances applied usually within the rectum or vagina can probably help avoid the rectal transmission of HIV, and some are being assessed in early Phase I safety studies.

One more approach, dubbed oral pre-exposure prophylaxis (PrEP), entails the usage of antiretroviral drugs to decrease the possibility of HIV in HIV-negative people.
