Predictive value of endometrial sonography in ovulation induction for intrauterine insemination.

This prospective study was undertaken to evaluate the prognostic value of the endometrial sonographic pattern on the day of human chorionic gonadotropin (hCG) administration in patients who underwent intrauterine insemination. The endometrial sonographic patterns were classified as homogenous, hyperechogenic (A), intermediate isoechogenic (B) and multiple-layered "triple-line" (C). Type A had no pregnancies, whereas type B had a 20% fecundity rate and type C had a 21.1% fecundity rate. The continuing pregnancy rate was 10% in type B, as compared to 19.3% in type C. The data suggest that the endometrial sonographic pattern on the day of hCG administration may be of predictive value regarding fecundity and continuing pregnancy in the intrauterine insemination cycle.
