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.
Prostaglandins play a very significant role as a local messenger in many normal functions, especially when cells are stimulated. This is important because anti-inflammatory drugs alter prostaglandin function whether they be from normal activities or inflammatory in nature.hey rapidly diffuse to other sites or are rapidly metabolized. Most prostaglandins are so rapidly metabolized, they do not reach the systemic circulation for redistribution. Migrating cells, especially phagocytes (cells which ingest; engulf), are directly involved with pain response.
