In the event that partner that is HIV-positive using antiretroviral therapy and contains a completely suppressed viral load (вЂundetectableвЂ™), the possibility of HIV transmission through rectal intercourse is zero. The PARTNER-2 research accompanied 783 male partners where the HIV-positive partner had an invisible viral load with no condoms were utilized in anal sex. No HIV transmission from HIV-positive partners took place and the researchers concluded that the risk of HIV transmission in these circumstances was effectively zero (Rodger) after 1596 couple-years of follow-up and 77,000 acts of unprotected anal intercourse. If viral load is detectable, condomless anal sex is an extremely efficient means of transmitting HIV, which is considered a high-risk task for both lovers, even though precise level of risk can rely on numerous facets.
For every condomless act by having an untreated HIV-positive partner, the possibility of disease is approximated at 1.38per cent (one in 72 chance) and 0.11per cent (one out of 909 possibility) for the receptive and insertive lovers correspondingly. But, it might be 10 to 25 times greater in the event that good partner is recently contaminated. Research reports have identified various other factors that further raise the threat of transmission.
Dangers to insertive and receptive lovers
There is certainly a belief that is widespread homosexual guys that the insertive partner (вЂtopвЂ™) are at really low threat of HIV disease. It really is true that HIV infection happens less frequently in guys whom entirely simply take the insertive part than in males whom take part in both functions, or males whom practise receptive rectal intercourse only (Jin).
