Changes in preantral and antral follicle population during ageing in the rat. The figure represents follicular quantification. Panel A corresponds to the total number of healthy and atretic preantral follicles and panel B corresponds to healthy and atretic antral follicles according to age. Results are mean value ± SEM of n = 4 experiments. a = p < 0.05 vs 6 months old; b = p < 0.05 vs 6, 8, 10 months old; c = p < 0.05 vs. 6, 10 months old.
