【摘要】 目的　探讨正常生理周期卵巢的动脉血流变化及其与卵巢功能、形态和激素变化之间的关系。方法　选择正常已婚妇女 70人 ,其中 5 0名中国人 ,2 0名英国人 ,经腹部超声均未发现子宫及卵巢疾病 ,在月经周期的卵泡前期、排卵期、黄体期和月经前期行经阴道彩色多普勒超声检查。结果　①正常人卵巢动脉血流与排卵周期有同步、相应的变化 ,阻力指数 (RI)在排卵时达最低点 (0 .44± 0 .0 4) ,在卵泡前期为最高点 (0 .5 4± 0 .0 4) ;②黄体期血流丰富且出现动静脉分流 ;③优势卵泡达 10mm时周边出现血流。结论　正常月经周期中卵巢动脉血流呈现相应的、有规律的周期性变化更多还原
