Figure 4. Correlation between serum testosterone levels and AR CAG repeat length.

Figure 4

A total of 251 male asymptomatic HBV carriers (AsCs) with normal liver enzyme levels were detected for serum testosterone levels. AR gene alleles were categorized by exon 1 CAG repeat numbers: S-CAG (CAG repeat number <19), M-CAG (CAG repeat number 19–20) and L-CAG (CAG repeat number >20). P value based on one-way ANOVA was given.
