Recently, the use of progesterone to prevent preterm labor, deemed decades ago to be ineffective, has been reexamined. Progesterone formulations and dosage regimens varied greatly between studies. In patients with prior preterm birth or shortened cervix shown on transvaginal ultrasound, progesterone appears efficacious in reducing the rate of preterm birth. However, this benefit was not demonstrated in multiple-gestation pregnancies. Overall, progesterone was well tolerated and appeared safe for mother and fetus. More studies are needed to confirm the dosage regimen and population that will benefit most from progesterone.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Progesterone appears to be safe and efficacious in reducing the risk of preterm birth in a select group of high-risk women with prior spontaneous preterm births and those with an ultrasound-confirmed short cervix.
