A new study reveals mechanics play a key role in pregnancy

The New York Times reports the success of a cervical pessary study in The Lancet today. The study claims the pessary device was successful at preventing preterm labor in a cohort of women at high-risk for preterm birth, identified by a ‘short’ cervical length in an ultrasound screening. It is still unclear how the pessary is able to maintain the cervix from dialating prematurely, but the results of this clinical trial are promising and provide evidence that the biomechanical properties of the pelvic region play a role in the progression of labor and cervical dilation.
