About video

Sperm washing consists of processing the sperm sample to eliminate the viral particles of the seminal plasma and the cells that may be hiv carriers, separating the mobile spermatozoa to be used in an assisted reproduction technique. Sperm washing can be used to decrease the risk of hiv transmission in hiv-positive males, because the infection is carried by the seminal fluid rather than the sperm. One italian study from 2005 of 567 serodiscordant couples treated with washed sperm resulted in no horizontal (to the woman) or vertical (to the child) hiv seroconversion. However, there is no 100 guarantee that washed sperm is free from the virus. Even after sperm washing, theres no 100 guarantee that hiv will not be transmitted. Ironically, sperm doesnt seem to be infected by hiv however, hiv may be present in the seminal fluid.   then the concentrated sperm is forced to swim through a gel, effectively washing them and leaving all hiv-contaminated material behind. Percoll gradient washing of 12 semen samples yielded six samples containing adequate sperm concentration for analysis. This washing procedure reduced prewash extracellular rna to below detectable limits in all cases proviral dna present in two of the six prewash samples was also reduced to below detectable limits after washing. How effective and safe is semen washing for hiv-serodiscordant couples? The issue 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.   sperm washing can be considered as a reproductive option for an hiv-discordant couple in which the man has hiv. Because the seminal fluid contains the highest concentration of hiv, the washed sperm contains little, if any, hiv. The sperm from all the hiv positive men was treated with sperm washing. The study shows there was no horizontal (in woman) or vertical (in child) hiv seroconversion. The study shows there was no horizontal (in woman) or vertical (in child) hiv seroconversion. Sperm washing is a technique that concentrates and separates the seminal fluid from the sperm in hivpositive males. When a woman wants to get pregnant, she is artificially inseminated with the sperm after it is washed and becomes virusfree.
