Abstract

Background: The aim of this study was to evaluate the effect of dydrogesterone in the outcome of idiopathic intrauterine growth restriction (IUGR). Materials and Methods: It is a double-blind randomized control clinical trial study that was done in Shahid Beheshti hospital of Isfahan during 2015–2016. In this study, 89 pregnant women with idiopathic IUGR fetus were selected and randomly divided into two intervention and control groups. Intervention group was treated with dydrogesterone 10 mg every 12 h for 2 weeks, while the control group received conventional management and treatment of IUGR, which also has been performed in the intervention group. Results: After 2 weeks of intervention, fetal weight was significantly increased in dydrogesterone group as compared to control group (2053.15 vs. 1736.36 g, P = 0.001); furthermore, we observed significant differences in the term of fetal abdominal circumference between the groups (27.25 vs. 25.92 cm, P = 0.006). Middle cerebral artery resistance index (0.67 vs. 0.83, P < 0.001) and uterine artery (UA) resistance index (0.68 vs. 0.81, P < 0.001) were significantly decreased in dydrogesterone group as compared to control group. Conclusions: Our results showed that dydrogesterone reduces resistance index of uterine artery and middle cerebral and increased fetal weight, while no sign of toxicity was observed. Dydrogesterone supplementation would have the potentiality to become a simple and economic means to prevent IUGR.
