As estrogen begins to stimulate uterine contractions, the uterus also produces hormones called prostaglandins. These also contribute to a decrease in progesterone levels. The release of prostaglandins helps initiate labor and, along with another hormone called relaxin, relaxes the muscles of the cervix.ut once labor is complete and the baby is no longer in the birth canal, the cervix is not being stretched anymore. This lack of the physical signal of stretching is what stops the positive feedback loop, and labor comes to an end.
When the body is functioning normally, baseline levels of prostaglandins are produced by the action of cyclooxygenase-1. When the body is injured (or inflammation occurs in any area of the body), cyclooxygenase-2 is activated and produces extra prostaglandins which help the body to respond to the injury.hey control processes such as inflammation, blood flow, the formation of blood clots and the induction of labour. Alternative names for prostaglandins Prostaglandin D2; prostaglandin E2; prostaglandin F2; prostaglandin I2 (which is also known as prostacyclin); a closely related lipid called thromboxane.
