NIH Progsterone Study

A National Institutes of Health study recently found that the hormone progesterone reduced the rate of preterm birth before week 33 of pregnancy by 45 percent among one category of at-risk women.

The results were recently published online in “Ultrasound in Obstetrics and Gynecology.” Joseph Hwang, M.D., led the study for the Perinatal Center of Iowa–the only study location in Iowa.
