Universal cervical length screening in singleton gestations without a previous preterm birth: ten reasons why it should be implemented

A short cervix is associated strongly with preterm birth. Pharmacologic intervention with vaginal progesterone in women with a singleton pregnancy and a short cervix in the second trimester decreases the incidence of preterm birth. We explore the evidence that universal cervical length screening in women with a singleton pregnancy meets the criteria for an effective screening test for preterm birth prevention, driving it towards becoming routinely offered in prenatal care.

Key words: prematurity, progesterone.
