(a) Combined weights and volumes of both ovaries from African elephant fetuses from mid-gestation onwards and calves up to 9 years of age (volumes were calculated using Cavalieri’s principle). (b). Relative contributions of cortex, interstistial cells and follicular antra to the volumes of the ovaries from African elephant fetuses (from mid-gestation onwards) and calves up to 4.5 years of age (volumes were calculated using Cavalieri’s principle. (c). The number of small follicles in the elephant fetus and prepubertal calf in relation to age. (d). Cortical volume of both ovaries combined of fetal and prepubertal ovaries of African elephants (volumes were calculated using Cavalieri’s principle.
