The values are expressed as mean ± SEM (). Number of pigmented cells: , early pregnancy versus nonpregnant; , mid pregnancy versus nonpregnant and early pregnancy; , late pregnancy versus nonpregnant and early pregnancy. Estradiol: , mid pregnancy versus early pregnancy, late pregnancy, and nonpregnant. Progesterone: , early pregnancy versus nonpregnant, , mid pregnancy versus early pregnancy, late pregnancy, and nonpregnant; , late pregnancy versus early pregnancy and nonpregnant. The significant differences were determined by Kruskal-Wallis test. |
