The PROLONG trial: Does 17-OH really prevent preterm birth?

Recently, the PROLONG Trial, investigating 17-OHP’s role in preventing recurrent preterm birth, called into question the effectiveness of this treatment regimen.

In this session, we will review both of these studies and put the results into proper perspective.
