Sonographic uterine predictors of pregnancy in women undergoing ovulation induction for assisted reproductive treatments.

OBJECTIVE

To determine preovulatory uterine sonographic predictors of pregnancy in women undergoing ovulation induction for assisted reproductive treatments.

DESIGN

Prospective evaluation of uterine sonographic and vascular flow profiles in women stimulated with leuprolide acetate and hMG.

SETTING

Private fertility center and tertiary-care academic center.

PATIENTS: Ninety-six women underwent 102 cycles of ovulation induction for IVF (46), GIFT (20), and zygote intrafallopian transfer (36).

MAIN OUTCOME MEASURES: Endometrial texture, thickness, resistance index at the first branch of uterine artery, diastolic blood flow, and pregnancy outcome (no conception, spontaneous abortion, and delivery).

RESULTS

Triple-lined pattern was predominant in women who delivered liveborn infants (P < 0.005). Endometrial pattern and diastolic blood flow were the only predictive markers of term pregnancy (P < 0.001 and P < 0.05, respectively).

CONCLUSION

Preovulatory triple-lined sonographic endometrial texture and the presence of end diastole blood velocities at the first branch of uterine artery are the most important uterine predictors of conception.
