Abstract
The study was performed in a prospective randomized fashion in order to
compare the value of tansvaginal ultrasound, and the value of combined colour
Doppler imaging of uterine, ovarian blood flow and transvaginal folliculometry in
assessment of ovulation induction of infertile women.
Ovulation rate was taken as the gold standard for assessment of ovulation induction
result.
Analysis of the results provided the following information: A) Better
sensitivity & specificity of colour Doppler indices in detection of ovulation. B) Better
timing of human chorionic gonadotrophin administration & better ovulation rate when
colour Doppler was used in cycle monitoring.
It can be concluded from the results of this study that combined use of
transvaginal sonography & colour Doppler imaging is more reliable in assessment of
ovulation & is more useful in monitoring of follicular growth and vascularity in
clomiphene citrate induced cycles than the use of transvaginal ultrasound alone.
The study opens a new field of ongoing research on the valuable application of
colour Doppler studies in the management of gynecologic infertility due to ovarian
cause.
KEY WORDS: Transvaginal ultrasound, colour Doppler, ovulation induction
