Abstract

OBJECTIVES:

To analyze our natural cycle IVF-ET experience in order to identify parameters predictive for success.

DESIGN:

Retrospective study.

SETTING:

Private-based reproductive center.

PATIENTS:

All patients who presented for IVF-ET interested in unmedicated cycles.

MAIN OUTCOME MEASURES:

Routine monitoring for IVF-ET was performed. In addition, serum values for FSH, PRL, E2, and P were analyzed.

RESULTS:

Day 3 FSH values were not useful, whereas elevated day 3 LH values adversely correlated with outcome. Age was the single most important predictor of success. With two cycles, 87.5% of pregnancies occurred.

CONCLUSION:

With proper patient selection, natural cycle IVF-ET results can be substantially improved.
