Semen parameters of a semen donor before and after infection with human immunodeficiency virus type 1: case report

Semen samples from a donor who seroconverted for human immunodeficiency virus type 1 (HIV-1) during the period that he was donating at our clinic were stored before and after infection. Semen analysis was done on all of these samples before cryopreservation. Retrospectively, both qualitative and quantitative HIV-1 testing was performed on the cryopreserved semen samples to determine the time of primary HIV-1 infection. After HIV-1 infection, semen volume, sperm motility and the percentage of spermatozoa with normal morphology were reduced compared with the same parameters before HIV-1 infection. HIV-1 RNA was intermittently detectable in semen. HIV-1 infection led to a reduction in semen volume, sperm motility and normal sperm morphology in this donor. However, the clinical significance of these findings is unclear. A longitudinal cohort study on the effects of HIV-1 infection on semen quality is necessary to confirm these findings.
