Injections of a progesterone-type hormone may be able to prevent more than a third of pre-term births in women with a history of giving birth early, reported Paul J. Meis, M.D., of Wake Forest University Baptist Medical Center, today (Feb. 6) at the Annual Meeting of the Society for Maternal-Fetal Medicine in San Francisco. “The evidence of this treatment’s effectiveness was so dramatic, the research was stopped early,” said Meis, the national principal investigator and a professor of obstetrics and gynecology at Wake Forest. “This drug is readily available and can be used by doctors to improve outcomes for mothers and babies.”
