Condoms in general. For example:

HIV sexual transmission risk among serodiscordant couples: assessing the effects of combining prevention strategies [AIDS. 2014 Jun 19; 28(10): 1521–1529]

Pay attention to the author list, because there is probably going to be quiz later on at some point.

EDIT: Condom and Nonoxynol-9 use and the incidence of HIV infection in serodiscordant couples in Zambia [25+ years ago now]
