Abstract
Three quarters of individuals infected with HIV are in their reproductive years and can expect an almost normal life expectancy under antiretroviral treatment. Many of them want to have a child and reproductive counselling and care can offer a sharp reduction in both sexual and vertical transmission rates. Most couples with HIV are formed by an infected man and an uninfected woman; in this setting, semen washing coupled with reproductive technology can be applied to eliminate the risk of sexual transmission of the virus. Semen washing is a processing method which reduces both HIV RNA and DNA to undetectable amounts. In couples in which only the woman is infected, self-insemination might be indicated. When both partners are carrying HIV, semen washing can be used in couples with different viral strains. HIV can be vertically transmitted and the risk of infection for the infant can be decreased to approximately 1% by reducing maternal viral load, elective caesarean section and avoidance of breastfeeding. In pregnancy the efficacy of antiretroviral treatment should be balanced against the possibility of embryonic or fetal toxicity. Caesarean section, performed electively, has proven its protective efficacy, without significant maternal morbidity. Its role should now be reassessed in mothers with undetectable viral load. Breastfeeding, discouraged to avoid postnatal transmission, might be possible in the future, with antiretroviral therapy capable of suppressing viral excretion in maternal milk. Semen washing, reproductive technology, antiretroviral therapy and obstetrical care can work in sequence to allow safe reproduction in couples infected with HIV.
