Answer

An apparent effect of hormonal contraception on HIV transmission to and from women has been reported, with a slight but statistically significant increase in transmission involving women on hormonal contraception. In a study of 3790 serodiscordant couples from Africa, the hazard ratios for transmission were 1.98 to, and 1.97 from women on hormonal contraception. Although barrier contraception should be employed in instances of serodiscordance anyway, this finding further strengthens that recommendation in those couples where the female partner is using hormonal contraception.
