The sperm washing procedure involves spinning a semen sample in a centrifuge to separate it into three parts.
Some researchers believe that the virus is carried in seminal fluids outside the sperm cells.
The technique, therefore, might be used to isolate HIV from sperm cells, which can then be used to impregnate a woman via artificial insemination. But, doctors warn, no method is foolproof. S emen is put in a centrifuge tube, along with a more dense solution. The solution helps to separate the semen as it is spun in the centrifuge. A fter being spun in the centrifuge, the specimen divides into three parts O nce they are separated, each of these parts are subjected to testing.
