What is Parturition?

Parturition means childbirth. It is a process of bringing forth a child from the uterus, ending pregnancy. It is usually initiated by the release of oxytocin hormone. 

Release of Oxytocin

The release of oxytocin hormone increases the contraction of uterine muscles. Prostaglandins are synthesized and released in response to the oxytocin hormone. 

Increase in Estrogen and Progesterone Ratio

An increase in estrogen and progesterone ratio is the indication of the initiation of the parturition process.

Prolactin Hormones

Prolactin hormones are released after the parturition in order to secrete the milk from the mammary gland.
