Figure 5. (A) Western blot analysis of endothelial NOS (eNOS) in monkey testicular lysates after testosterone (T), heat (H), or T+H treatment. Data are representative of 3 to 4 animals at each time point from 1 of 3 separate experiments. Actin in the immunoblot is shown as a loading control. (B) Densitometric analysis shows no significant (P < .05) changes in eNOS levels after these interventions. Values are means ± SD. D and d indicate number of days after treatment.
