Assessment of ovarian response with color Doppler ultrasonography in vitro fertilization-embryo transfer / 中华超声影像学杂志

ABSTRACT

8 oocytes) according to the number of oocytes collected in one ovary. On day of human chorionic gonadotrophin injection, PSV, EDV, PI, RI, S/D of ovarian stromal artery in the ovarian were detected and perifollicular vascularity were graded with color Doppler ultrasonography. Results Not only PSV and EDV of stromal artery but also perifollicular vascularity in low-response group was significantly lower than that of normal-response and high-response groups. PSV and EDV of ovarian stromal artery and perifollicular vascularity were highly interrelated with ovarian response. Conclusions The increase of PSV and EDV of ovarian stromal artery and perifollicular vascilarity indicate the improvement of perfusion in ovary and ovarian response.
