Interestingly, follicle diameters are significantly different
between the four species at the primordial stage, when
compared using ANOVA (p < 0.005). Thereafter, follicle
sizes converge at the primary and preantral stages only to
then see a dramatic disparity with a smaller follicular
diameter of the mouse as compared to hamster and pig
follicle size at the incipient antrum stage onward (p <
0.001). The pig and hamster diverge from similarity at the
early antral stage (p < 0.001).
