title: The risk of fetal anomalies as a result of progesterone therapy during pregnancy.
abstract: The incidence of congenital anomalies in infants born to 382 women treated with P was noted. Only five anomalies occurred in the infants born to women who had taken P. This study supports the data of Rock et al. by demonstrating a similar low incidence of birth defects in a much larger series of patients who also took a much higher dosage of P. Similarly, because only 1 of 189 patients treated with both P and 17-OHP developed anomalies, the data supports the study by Katz et al., suggesting no increase in anomalies related to 17-OHP therapy.
