摘　　要：对广西百色地区456例壮族正常胎儿的乳晕外形进行现察和测量,结果表明:胎儿的乳晕随着胎龄的增长而增大.从13周开始,乳晕出现率为100％,21～24周,有0.95％的胎儿乳晕稍隆。37周后乳晕稍隆率为100％.乳晕的直径随着胎龄的增大而增大,但其生长速度有一定的波动性.经回归分析,乳晕直径与胎龄有明显的线性关系(P<0.01).根据乳晕的直径,可以对胎龄进行预测.The areolar contours in normal fetuses were observed and measured. The results showed that areolae grew as gestational age increased; the occurrence rate of areola was 100% from the 13th week; 0.95% of the areolae was a little prominent from 21th to 24th week and the prominence rate was 100% after the 37th week; the diameter of the areola increased as gestational age increased but the growth velocity had a certain fluctuation. There were obvious linear relationship between areolar diameter and gestational age (p < 0.01). It is suggested that gestational age might be predicted with areolar diameter.
