Comparison of the Efficacy of Two Vaginal Progesterone Formulations, Crinone 8% Gel and Utrogestan Capsules, Used for Luteal Support in Blastocyst Stage Embryo Transfers

Accepted 20 June 2009.

Summary

Objective

To compare the efficacy of two vaginal progesterone formulations, Crinone gel and Utrogestan capsules, for luteal phase support in blastocyst stage embryo transfers.

Materials and Methods

We analyzed 460 consecutive cycles in patients undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI)–blastocyst transfer (BT) treatment at our institution between January 2004 and December 2007. Patients applied either Crinone 8% vaginal gel (90 mg, once daily) or Utrogestan vaginal capsules (200 mg, four times daily) for luteal supplementation. Progesterone was administered from the day of oocyte retrieval to pregnancy confirmation. Clinical pregnancy and implantation rates were the main outcome measures.

Results

The clinical pregnancy rate (58.7% vs. 44.3%) and implantation rate (32.04% vs. 23.89%) were significantly higher in the Crinone group compared with the Utrogestan group after IVF/ICSI–BT treatment.

Conclusion

Luteal phase support with Crinone 8% vaginal gel (90 mg daily) resulted in better clinical pregnancy and implantation rates than Utrogestan vaginal capsules (200 mg, 4 times daily) in IVF/ICSI–BT cycles.
