Outcome of Vaginal Progesterone as a Tocolytic Agent: Randomized Clinical Trial
Vaginal progesterone has a potential beneficial effect in postponing of preterm labor by suppression of prostaglandins cascades. Although different studies evaluated the use of progesterone for preterm birth, the exact effect of which on prolongation of pregnancy remains unclear. Seventy two women who underwent preterm labor were managed by magnesium sulfate. Then they were randomly assigned to continue pregnancy either by applying vaginal progesterone (400 mg) until delivery or without using any drug. Gestational age mean at the time of delivery (P = 0.039) and postponing delivery mean time (P = 0.048)
were significantly higher in progesterone group. Comparison of neonatal outcomes between two groups of patients showed meaningful benefits of progesterone in increasing of neonatal weight, reduction of low birth weight babies, and lowing neonate admitted in NICU
In vitro fertilization outcome in frozen versus fresh embryo transfer in women with elevated progesterone level on the day of HCG injection: An RCT
Background: The effect of elevated progesterone level on human chorionic gonadotropin (HCG) day in in vitro fertilization cycles is controversial. Some suppose that rise in progesterone level seems to have a negative impact on implantation and pregnancy by desynchronizing the endometrium, while others disagree. Objective: To evaluate the superiority of the frozen cycle over fresh cycle on live birth in patients with elevated progesterone level on HCG day. Materials and Methods: In this double-blind, randomized clinical trial, 72 women undergoing assisted reproductive technology with elevated progesterone level (≥1.8 ng/dl) on HCG day were included. The participants were grouped by fresh versus frozen embryo transfer, randomly. Finally, the clinical pregnancy and live birth rate were compared. Results: The implantation rate was 21.51%. The clinical pregnancy rate was 47.22% in fresh embryo transfer group (17/36) and 41.66% in frozen group (15/36) (p=0. 40). The live birth rate was not significantly difference between two groups (p=0.56). Conclusion: None of the fresh and frozen cycles are superior to the other and we recommend individualizing the decision for each patient. The frozen cycle may impose more emotional stress on patient
