Shown are immature ovaries of a female (A), and immature testes (B) and sexually maturing testes of males (C) with higher magnification insets in each. Cortical alveoli (CA); early lipid droplets (LD); type-A spermatogonia (SG-A); type-B spermatogonia (SG-B); spermatocytes (SC); spermatids (ST); spermatozoa (SZ). Scale bars are 100 μm in main images; higher magnification inset widths are 150 μm for panel A and 50 μm for panels B & C.
