HIV tests in men should be accompanied also by examination of sperm in the semen. Because apparently the existing population of HIV in semen is different from the ones in the blood, so that it is not represented only by blood tests alone.
This difference was revealed when researchers compared the genetic code on the surface of HIV protein that exist in both types of these body fluids. Presumably, the differences arise from changes that occur in the genital tract where semen is produced.
Inside these channels, researchers have revealed two virus growth mechanisms that causes AIDS. Although both originated from blood, HIV will experience a change in accordance with the mechanism of growth experienced. (more…)
