Yolk testosterone concentrations in the middle layer were also lower in the corticosterone implanted females, but this difference did not reach statistical significance (3.1±0.1 ng/g and 3.6±0.1 ng/g in yolks of corticosterone- and placebo pellet-implanted females respectively; treatment: χ 2 = 2.7; df = 1; p = 0.099; treatment*time: p≥0.08 for all layers in the respective models).
