The effects of angiotensin-coverting enzyme (ACE) inhibitors on the number of germ cell types in the seminiferous epithelium cycle. The germ cells present at stages (a) I, (b) V, (c) VII/VIII, and (d) XII of the seminiferous epithelium cycle were counted in all conditional treatments. The data are presented as the mean ± SEM; various superscripts designate significant differences between the analyzed groups as assessed using one-way ANOVA followed by the Tukey test as a post hoc test (a, p < 0.01; b, p < 0.001; c, p < 0.0001). SC, Sertoli cell; SPG(A), type A spermatogonium; SPG(B), type B spermatogonium; SP(Pl), preleptotene spermatocyte; SP(Z), zygotene spermatocyte; SP(P), pachytene spermatocyte; MF, meiotic figures; SS, secondary spermatocyte; RP, round spermatid; C, control; CAP, captopril; (inv)10c, containing the inverted BPP-10c sequence; 10c, BPP-10c; 11e, BPP-11e; AP, BPP-AP
