Group A selective cesarean section without any birth pain ( n =18),Group B cesarean section in latent phase( n =10),Group C cesarean section in active phase( n =12),Group D spontaneous vaginal deliver( n =60). Results The concentrations of fetal umbilical cord cortisol in spontaneous vaginal deliver group was gradually increased with gestational week. The peak level was in the 39th gestation week,by the 42th gestation week,the concentration of cortisol declined to the 37th gestation week. DHEA S changed paralleled with cortisol ( r =0.46, P
