Can continued semen exposure increase HIV resistance?
scientists have found that continuous exposure of semen sex workers supporting the changes in the vaginal microenvironment and cervical in a way that can actually increase HIV resistance.
boat continued cum increased exposure of HIV drug resistance?
The findings could open the way to better preventive strategies that block transmission of the virus and improve designs for future studies of HIV vaccines.
In some areas of the world where HIV prevalence is highest, a small number of female sex workers continue to put negative test for infection despite repeated sexual activity and low rates of condom use.
However, the reason why these women are protected from HIV infection has eluded scientists, as they seem to have none of the known anti-HIV immune responses itself.
"Making the link between sex work, changes in the immune status and semen exposure gives us an important piece of information that will hopefully help to establish whether exposure semen chronic and its effects on the female reproductive tract can contribute to the resistance of HIV in sex workers do not become infected despite the low condom use, "said study lead author Luis Montaner, professor at the Wistar Institute in Philadelphia, U.S.
eralier studies have shown that long-term sex work does not always result in an infection. Thus, in this study, researchers analyzed long term San Juan in Puerto Rico who tested negative for HIV-1 virus and compared them with a group of women with self-reported exposure a cohort of female sex workers low semen recruited in the same area.
The groups were also compared based on rates of unprotected sex, what types of contraceptives sex workers who had some sexual activity infections were used (if any) and excluded transmission such as chlamydia or syphilis.
researchers identified three different mechanisms that may contribute to decreased infection rates among sex workers.
"It is important to note that the study ignores sex without a condom, since this increases the overall risk of HIV infection and other sexually transmitted diseases "Montaner said.
"instead, this study identifies unexpected exposure semen long term can have on the cervix and vagina which can reduce but not eliminate the risk of effects infection, "Montaner said.
study results were published in Journal mucous Immunology.
