Objective To investigate the effect of castration on heart function in male rabbits postinfarction congestive heart failure model. Methods 32 male 4-5 months old New Zealand rabbits were randomly assigned to ligation of first branch of left coronary artery or sham operation (sham group, n=8). 3 weeks later 20 survived MI model rabbits were randomly subjected to castration (castration group, n=10) or sham operation (MI group, n=10). Serum FT, DHEAS levels and LVEF were checked at week 0, 3 and 15. Heart diameter and left ventricular wall thickness were measured at week 15. Results The serum FT and DHEAS levels decreased significantly at week 3. In MI group and castration group serum androgen level was lower and heart weight, ventricular diameters, ventricular wall thickness corrected by body weight were higher than that in sham group at week 15. The androgen level and body weight of castration group were lower than that in MI group. But LVEF in castration group was not higher than MI group. Conclusion There was no benefit effect of castration on heart function in male rabbits postinfarction congestive heart failure model.
