Condom use is much more effective at preventing male to female transmission than vice-versa – HERPES

Condom use is much more effective at preventing male to female transmission than vice-versa.[27] The effects of combining antiviral and condom use is roughly additive, thus resulting in approximately a 75% combined reduction in annual transmission risk.[citation needed] These figures reflect experiences with subjects having frequently-recurring genital herpes (>6 recurrences per year). Subjects with low recurrence rates and those with no clinical manifestations were excluded from these studies
