Discordance in HIV‐1 viral loads and antiretroviral drug concentrations comparing semen and blood plasma

Abstract

Because, at least in part, of poor drug penetration into the genital tract, an undetectable HIV viral load in the BP does not guarantee an undetectable viral load in semen. In view of this, caution should be taken in concluding that patients on HAART with suppressed viraemia are sexually non-infectious.
