Oxytocin Receptors and Cell Signaling in Uterine Muscle

Oxytocin receptor expression in the human uterus peaks at labor onset and declines sharply during advanced labor and postpartum.

• Oxytocin is commonly used in obstetrics to induce labor and prevent postpartum hemorrhage.
• The sensitivity of the uterus to oxytocin may differ among pregnant women due to variations in oxytocin receptor expression.
• Oxytocin receptor expression is regulated by factors such as steroid hormones, physical stretching of the uterus, and inflammation.
• Understanding the regulation of oxytocin receptor expression could provide insights into labor mechanisms.
