However, little is known about changes in testosterone following successful HCV treatment.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>We evaluated testosterone levels and the prevalence of low testosterone in a cohort of 327 men with chronic HCV infection (human immunodeficiency virus [HIV] coinfection = 150) and in a subset of 85 men with testosterone levels obtained pre-HCV treatment and after sustained virologic response (SVR).

Low TT (&lt;10.4 nmol\/L) was more prevalent in participants with SVR compared with active HCV (P = .002); however, low FT (&lt;0.1735 nmol\/L) was common (50% active HCV, 43% SVR) and did not different between groups. For participants with longitudinal determinations, TT and SHBG decreased significantly (P &lt; .0001) while FT remained unchanged post-SVR. Low FT persisted after SVR (pre-treatment 58%, post-SVR 54%, P = .72). HIV status and change in aspartate aminotrasferase-to-platelet ratio were significant independent predictors of change in FT following SVR.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>During active HCV infection, testosterone deficiency may be masked due to elevated SHBG.
