Granulosa cell proliferation on experimental day 1. (a) Low-power magnification of an ovarian cross section; (b) intermediate-power magnification of class 5b or early class 6 follicles from each experimental group. C, control group follicle; S, PMSG-stimulated follicle; T, treatment group follicle. Proliferation is seen as black dots. Counterstaining is with methyl-green.
