Semen is a major transmission vector for HIV. Virus-specific CD8 T cells are critical in HIV control, but their relationship with semen viral load is unknown. We therefore examined the association between systemic HIV-specific IFN-gamma CD8 responses and viral load in the semen and blood of HIV-infected men. No correlation was observed between viral load in either semen or blood and systemic CD8 T-cell responses. Further studies of immune correlates of semen HIV shedding are needed.
