Oxytocin is continually released throughout childbirth through a positive feedback mechanism. As noted earlier, oxytocin prompts uterine contractions that push the fetal head toward the cervix. …

In this review, we discuss the HPA axis as the central regulator of various physiological responses to stressors. We also examine the activational and organizational effects of hormones during …
