Lundgren cautioned that the outcomes for heterosexual are extra sure than these for homosexual males, and the continuing examine will proceed to supply higher numbers about their danger.
“The message to heterosexual is that the danger of HIV transmission by way of condomless vaginal intercourse is extraordinarily low and sure negligible,” Lundgren mentioned, so long as the HIV-positive individual has been on full antiretroviral remedy for a number of months and makes use of the treatment constantly.
For homosexual male , the danger is “very low,” he mentioned, however the analysis does not but affirm it is “extraordinarily low.”
Why do some desire intercourse with out condoms?
Rowena Johnston, vp and director of analysis at amfAR, the Basis for AIDS Analysis, mentioned, “If we’re sincere and speak about what occurs in the actual world, just about everybody thinks condomless intercourse feels higher. That is what they need to transfer to if they will.”
For like these within the examine, the analysis “suggests that may not be a really dangerous proposition, however any researcher would discover it exhausting to advocate that you simply needn’t use condoms in any respect,” Johnston mentioned.
