What is the primary function of PGF2α?

The primary function of PGF2α, or prostaglandin F2 alpha, is to induce uterine contractions. This role is especially crucial during labor, where PGF2α contributes to the rhythmic contractions of the uterus, ultimately facilitating childbirth. It acts on specific receptors in the uterus to enhance contractility, and its levels increase significantly during late pregnancy and labor, highlighting its importance in the parturition process.

While it may have other physiological roles, such as influencing blood pressure through vasoconstriction in certain contexts, its most notable and critical function in the realm of maternal-fetal medicine is associated with the induction of labor and uterine dynamics. This makes it a vital component in managing labor and delivery scenarios.
