Ovary morphological analysis. a-c: Morphological findings for the ovaries. Ovarian mass index = ovary weight (g) / body weight (g); d: The primordial follicle to antral follicle ratio determined by in vivo ovarian analysis (n = 10). e: The antral follicle to total follicle ratio (n = 10). f: H&E staining of follicles in different stages in WT and Fndc5 mutant mice. Black arrowheads, primordial follicle; yellow arrowheads, primary follicle; red arrowheads, antral follicle. *P < 0.05 compared to WT mice
