The effect of stress on the level of estradiol. (a) Schematic representation of estradiol dynamics during the estrous cycle of mice. Symbols indicate estradiol levels in the groups of experimental animals. Triangles: no-treatment control group (NC), circles: HD group, and squares: MS group. (b) The impact of early-life stress on the concentration of 17β-estradiol in the serum of female mice. Data are with in the NC group, in the HD group, and in the MS group.
