Use of versant TMA and bDNA 3.0 assays to detect and quantify hepatitis C virus in semen.

Previous findings of hepatitis C virus (HCV) in human semen have been inconsistent. This study attempted to elucidate the presence of HCV in semen from 80 HCV RNA blood plasma positive homeless men using two novel non-PCR based techniques. Semen was frozen immediately upon ejaculation in order to preserve virus quantity.

Presence and predictors of hepatitis C virus RNA in the semen of homeless men.

Although the possibility of sexual transmission of the hepatitis C virus (HCV) remains controversial, little is known of the associations ofpositive semen specimens with potential demographic and behavioral risk factors. Knowledge of these predictors may suggest factors that increase risk of HCV RNA in the semen. Semen and bloodfrom 80 HCV-infected homeless men were evaluatedfor the presence of HCVRNA by means of branch DNA and transcription-mediated amplification analyses.
