Which of these is not an important component of initiation of parturition in humans?
Increase in estrogen and progesterone ratio
Synthesis of prostaglandins
Release of Oxytocin
Release of Prolactin
Solution
During parturition, secretion of progesterone decreases, thus estrogen and progesterone ratio increases. Prostaglandins facilitate dilation of the cervix, and oxytocin causes contraction of the myometrium. Prolactin helps in the process of lactation.
