Objective: To estimate whether the use of 17 alpha-hydroxyprogesterone caproate (17P) in women with an ultrasound-indicated cerclage (UIC) reduces the rate of preterm birth (PTB).
Conclusions: Among women with a prior spontaneous PTB and current UIC for CL<25mm, 17P did not reduce the rate of PTB <35 weeks.
