Resumen

Semen transmission of human immunodeficiency virus (HIV) drives the global pandemic. HIV loads are generally lower in semen than in blood, but semen loads may be disproportionately high in a subgroup of men. HIV loads in semen exceeded those in blood in 9 (35%) of 26 of antiretroviral therapy-naive men, and disproportionately high shedding was strongly associated with compartmentalized semen cytomegalovirus (CMV) reactivation (odds ratio [OR], 10.5; P < .01). Overall, 17 of 26 participants were shedding CMV in semen. Semen levels of HIV and CMV were closely correlated (r = 0.5; P < .01), independently of blood HIV load and CD4⁺ T cell count. Prevention of CMV reactivation warrants further study as a possible strategy to reduce semen shedding of HIV.
