Association of endogenous progesterone levels in young women using hormonal contraception with recent HIV-1 infection.

Among women using hormonal contraception, DMPA or NET-EN we did not observe a significant difference in progesterone levels between women with recently acquired HIV infection and women who remained HIV negative. Our findings suggest that endogenous progesterone levels remain suppressed in the presence of hormonal contraception and are not likely to be associated with HIV acquisition.
