Testis size and gene expression in D3 and TRα1 double deficiency. A, Relative testis weight in adult mice of the 4 genotypes. B, Testicular gene expression of Inha, Inhba, Inhbb, and Fst, of adult mice of the 4 genotypes. Data represent the mean ± SEM of determinations in 4 animals per group. Statistical significance was determined by the ANOVA and Tukey's post hoc test. *, P < .05 and ***, P < .001, when compared with the WT group; #, P < .05, when compared with the D3KO group.
