Summary: In a new study,
scientists have found that continued semen exposure in sex sustains changes in the cervical and vaginal microenvironment in a way that may actually increase HIV-1 resistance.
"a small number of female continue to test negative for the infection despite repeated sexual activity and low rates of condom use. However, the reason as to why these women are protected from HIV infection has eluded scientists, since they seem to have none of the known immune responses against HIV itself"
"Making the link between chronic semen exposure and its effects on to the female reproductive tract"
"It also clearly indicates that women are equipped to activate mechanisms of resistance due to sex itself, which we did not expect to find at the start of this research."
"Prior studies have shown that long-term sex does not always result in infection. frequency of intercourse may change the immune and female reproductive areas exposed to virus."
"It is important to note that the study does not make a case for sexual intercourse without a condom, as doing so will increase the overall risk of HIV infection and other sexually transmitted diseases," Montaner said. "Instead, this study identifies unexpected effects that long-term semen exposure may have on the cervix and vagina that may lower but not remove the likelihood of infection."
