Which of these is not an important component of initiation of parturition in humans

Options

A. Synthesis of prostaglandins
B. Release of Oxytocin
C. Release of Prolactin
D. Increase in estrogen and progesterone ratio

Answer

C

Explanation

• At the end of gestation, the completely developed foetus is expelled out. This process is called parturition. Prolactin is a lactation hormone that has no role in initiation of parturition in humans.
• Prostaglandins, which stimulate uterine contractions are also produced that act on myometrium.
• Oxytocin, the main hormone, also called as birth hormone is released by maternal pituitary, which brings about strong uterine contractions.
• Estrogen and progesterone ratio increases as estrogen levels rise significantly.
