The importance of progesterone in the maintenance of mammalian pregnancy is well established1–18. Similarly, a decline in progesterone action is believed to be central to the initiation of parturition in most mammalian species, including primates5,7,8,12–14,19,20, although the precise mechanism for this in humans has not been elucidated5,7,9,13,14,21–25. Progestogen (a term that, like progestin, includes both ‘natural’ progesterone and synthetic compounds with progesterone action)26…

Progesterone is a key hormone for pregnancy maintenance, and a decline in progesterone action is considered to be central to the initiation of parturition in most mammalian species, including primates, so it is not surprising that many investigators have explored the use of progestersone for the prevention of preterm birth.

Understanding that high-risk populations are not homogeneous and no single-approach modality is likely to be generally applicable, this work has combined the available evidence on both progesterone and cerclage to provide guidance on how to identify subgroups of women at significantly increased risk for PTB and how to preferentially consider progester one versus cerClage.

The administration of vaginal progesterone after tocolysis in threatened preterm labor is associated with prolongation of pregnancy, and the reduction of deliveries before 34 weeks was observed in patients presenting with contractions after 27 weeks gestation.
