Mean percentage change in circulating total testosterone and androstenedione concentrations following ovariectomy in monkeys with low (Low, n = 9), intermediate (Int, n = 9) and high (High, n = 8) primordial follicle counts and the entire cohort. Error bars represent standard error of the mean. Ovariectomy significantly decreased circulating testosterone and androstenedione serum levels (p < 0.01), but the percentage change was not significantly different (p > 0.05) among the tertiles
