HIV and germinal cells: how close an association?
Whether semen from someone who is HIV-positive can be prepared so that it is safe for insemination is a critical question particularly to couples in which the male is seropositive and the female is seronegative. It is reassuring that some investigators have reported great success in using sperm washing to dramatically reduce HIV levels in the ejaculate. Such reports suggest that if free virus and leukocytes in the seminal plasma are removed, the specimen may be safe for insemination. Whether the virus ever is associated with spermatozoa themselves is not fully understood. In situ hybridization as well as electron microscopic studies have suggested the presence of viral particles but whether these are preparation artifacts or evidence of viable viral DNA is not known. Studies of whether the virus is incorporated into developing spermatozoa or is shed in the reproductive tract will aid in the elucidation of sexual transmission of HIV.
