Question

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

• A. Synthesis of prostaglandins
• B. Release of oxytocin
• C. Release of prolactin
• D. Increase in estrogen and progesterone ratio

Answer 1

The correct option is C Release of prolactin

• Parturition is a phenomenon of giving birth. It is a process of delivering a child from the womb to the outside. It is usually initiated by the release of oxytocin hormone.
• This hormone increases the contraction of uterine muscles. Prostaglandins are synthesized and released in response to the oxytocin hormone. Also, an increase in estrogen and progesterone ratio indicates the initiation of the parturition process.
• Prolactin hormones are released after the parturition in order to secrete the milk from the mammary gland.

Thus, the correct answer is 'Release of prolactin.'
