Reproductive assistance to HIV-discordant couples--the German approach.

An estimated 35 000 Germans are infected with HIV, and 75% of these are of childbearing age. Couples with one infected partner are faced with the risk of infection of the healthy partner. By using assisted reproduction techniques (ART) and virus-free sperm it is possible to fulfil the desire for children while minimising the risk of acquisition of infection. Therefore since 1991 in Germany ART is offered to couples of HIV-positive males and seronegative females. However, established programmes in different centres were temporarily suspended due to serious doubts about the reliability and safety of the sperm preparation technique (density gradient centrifugation and swim-up). -. Since 1997 processed sperm samples are routinely tested for HIV by highly sensitive detection methods and cryopreserved. Only if the test is negative are the processed spermatozoa used for homologous insemination, in-vitro fertilization or intracytoplasmatic sperm injection. This procedure removes most medical as well as legal considerations. At present 3 reproductive units in Germany offer reproductive assistance to HIV-discordant couples, and a further 9 institutions plan to establish that procedure. From 1991 to 1999, 54 women were treated by ART. 30 pregnancies occurred and 24 children were born. So far no maternal or infant infection was observed after treatment.
