Abstract
To assess intraovarian blood flow Doppler parameter during the natural and controlled ovarian hyperstimulation cycles in early follicular, periovulatory and midluteal phase each other.
Serial measurement throught the menstrual phase in natural 9 cases and controlled ovarian hyperstimulation cycles 14 cases. We measure the doppler parameter which were PI, RI, and A/B ratio by transvaginal ultrasound-color flow doppler.
No differences were observed between the two groups. During the natural cycle, ovarian blood flow velocity has a pulsatility index(PI) was 0.68, 0.68 and A/B ratio was 3.37, 3.38 respectively, which were not statistically significant. And so, during the controlled ovarian hyperstimulation cycle blood velocity was a PI of 1.43, 1.38, 0.87 in early follicular, periovulatory and midluteal phase, RI was 0.67, 0.66, 0.77 and A/B ratio was 3.29, 2.42, 2.35 respectively, which were not statistically significan, too.
Transvaginal ultrasound-color Doppler velocimetry is easy application and comfortable to physician and patient. And the image of pelvic organ and pathophysiologic condition are concerned by sonogram tools especially doppler measurement. We think that the sonographic information are very available to evaluated clinical result and outcome, of ART future.
