To compare the efficacy of Crinone 8% intravaginal progesterone gel vs. IM progesterone for luteal phase and early pregnancy support after IVF-ET.
Randomized, open-label study.
Academic medical center.
PATIENT(S): Two hundred and one women undergoing IVF-ET.
INTERVENTION(S): Women were randomized to supplementation with Crinone 8% (90 mg once daily) or IM progesterone (50 mg once daily) beginning the day after oocyte retrieval.
MAIN OUTCOME MEASURE(S): Pregnancy, embryo implantation, and live birth rates.
RESULT(S): The women randomized to luteal phase supplementation with IM progesterone had significantly higher clinical pregnancy (48.5% vs. 30.4%; odds ratio [OR], 2.16; 95% confidence interval [CI], 1.21, 3.87), embryo implantation (24.1% vs. 17.5%; OR, 1.89; 95% CI, 1.08, 3.30), and live birth rates (39.4% vs. 24.5%; OR, 2.00; 95% CI, 1.10, 3.70) than women randomized to Crinone 8%.
CONCLUSION(S): In women undergoing IVF-ET, once-a-day progesterone supplementation with Crinone 8%, beginning the day after oocyte retrieval, resulted in significantly lower embryo implantation, clinical pregnancy, and live birth rates compared with women supplemented with IM progesterone.
