Serum testosterone (T) levels, systolic blood pressure and relative kidney weight at 15 weeks of age for SHR/y and WKY gonadally intact control (control), castrate (cast) and castrate with T implant (cast+Ti) males, expressed as means +/- SEM. The two-way ANOVA for serum T was significant for T treatment) F = 226.0, p < 0.001). Both T implant groups had elevated T compared to controls (+++ = p < .001). The two-way ANOVA for SBP was significant for T treatment (F = 8.1, p = 0.005), strain (F = 6.2, p = 0.001), and T treatment x strain (F = 4.9, p = 0.003). The two-way ANOVA for T treatment on relative combined kidney weight was significant (F = 99.1, p < 0.001). The SHR/y control group SBP was greater than the SHR/y cast+Ti (+++ = p < 0.01) and SHR/y cast group SBP (&&&= p < 0.001). The WKY cast group SBP was less than the WKY cast+Ti and control groups (% = p < 0.05). Relative combined kidney weight for SHR/y cast was significantly less than SHR/y control and SHR/y cast +Ti groups (### = p < 0.001). relative combined kidney weight for the SHR/y cast +Ti group was significantly greater than the SHR/y cast and control groups ($$ = p < 0.01).
