To determine if the lateral ventricular atrial diameter differs between male and female fetuses at 20-24 weeks' gestation.
Prospective study.
The transverse diameter of the ventricular atrium was measured from inner wall to inner wall for a total of 202 pregnant women with 105 male fetuses and 97 female fetuses.
The mean diameter of the ventricular atrium for the 202 fetuses was 4.96 +/- 0.96 mm (range, 2.1-8.4 mm). The 105 males had a mean diameter of 4.95 +/- 0.98 mm and the 97 females a mean diameter of 4.97 +/- 0.94 mm. There was no statistical difference between the sexes.
In our population, there was no difference between ventricular atrial diameter in male and female fetuses at 20-24 weeks' gestation.
确定妊娠20 - 24周时，男性和女性胎儿的侧脑室心房直径是否存在差异。
前瞻性研究。
对总共202名孕妇进行研究，其中有105名男性胎儿和97名女性胎儿，测量心室心房的横径，测量是从内壁到内壁进行的。
202名胎儿的心室心房平均直径为4.96 +/- 0.96毫米（范围为2.1 - 8.4毫米）。105名男性胎儿的平均直径为4.95 +/- 0.98毫米，97名女性胎儿的平均直径为4.97 +/- 0.94毫米。两性之间无统计学差异。
在我们的研究人群中，妊娠20 - 24周时男性和女性胎儿的心室心房直径没有差异。
