How effective and safe is semen washing for HIV-serodiscordant couples?It's possible for couples to have a safe and successful pregnancy, and prevent HIV transmission to the uninfected partner and the baby. Jeniffer F. Kawwass, of the CDC's Division of Reproductive Health, National Center for Chronic Disease Prevention and Health Promotion, and her colleagues, explain sperm washing is a risk-reduction strategy that involves separating sperm from infected cells in the seminal fluid, and using the sperm for intrauterine insemination IUI , or in vitro fertilization IVF treatment. This method is seen as an "extra step" that will ensure the virus isn't transmitted.
Jump to navigation. Sperm washing is a technique that concentrates and separates the seminal fluid from the sperm in HIV-positive males. When a woman wants to get pregnant, she is artificially inseminated with the sperm after it is washed and becomes virus-free. Sperm washing is done with the help of a centrifuge. The centrifuge is a device that spins at a high speed to separate the sperm from the seminal fluid in a given sample of semen. The sperm is then purified in a solution twice, in order to clean other unwanted substances in it, including the HIV. This technique was first introduced in in Milan, Italy by Augusto Enrico Semprini and colleagues, with the aim of helping HIV positive couples to conceive a healthy baby and to ensure that females do not acquire the disease from an HIV-positive male. Nowadays, many couples opt for sperm washing because it prevents the female partner from getting infected with HIV and enables the HIV positive male to propagate a healthy family.
The CDC endorsed the use of a processing technique for the semen of HIV-positive men for the purpose of artificial insemination, according to the agency's most recent Morbidity and Mortality Weekly Report. The new report marks the first time the agency has backed sperm washing as a viable and safe conception technique for these HIV-discordant couples. The approval represents a reversal on a recommendation that has stood for more than two decades. Previously, the agency had endorsed conception among couples with HIV-positive men and HIV-negative women when both parties used antiretroviral drugs to prevent viral transmission.
The prevalence of the human immunodeficiency virus HIV in people of reproductive age, together with improvements in life expectancy and quality of life in HIV-positive people receiving highly active antiretroviral treatment HAART , have meant that more serodiscordant couples are considering having children. Adoption and donor insemination are alternative, safe options, but due to legal restrictions they are only offered in a few centres and countries. For couples who choose to have biological children, the present options are conception via unprotected sexual intercourse and conception via semen washing. The rate of HIV transmission for unprotected heterosexual intercourse seropositive male to seronegative female is estimated to be around one HIV transmission for every thousand contacts. The transmission rate may be higher in people with a high viral load or in the presence of other sexually transmittable infections. Usually, when attempting to have biological children, couples are advised against unprotected intercourse, as the priority is to prevent infection in the uninfected woman and her fetus. The application of semen washing to reproduction assumes that spermatozoa are not a major reservoir for HIV. The method involves three-steps:.
