关于反复流产夫妇的细胞遗传学问题曾有过不少研究。1972年作者复习了17篇此类文章,发现在1973名男女染色体组型中有25个人的染色体结构异常,其发生率(1.3％)较普通成人(0.3％)高四倍。最近对自然流产胚胎的细胞遗传学研究指出,所有染色体异常的流产胚胎中,由于不平衡易位者占2～4％。 给783名自然流产者(女483,男370)做了短期 There have been many studies on the cytogenetics of recurrent abortion couples. In 1972, the authors reviewed 17 such articles and found that there were 25 chromosomal abnormalities in 1973 genotypes for men and women, with a rate (1.3%) four times higher than in normal adults (0.3%). A recent cytogenetic study of spontaneous abortions of embryos has shown that 2 to 4% of unbalanced translocators are present in all aborted embryos with chromosomal abnormalities. A total of 783 spontaneous abortions (female 483, male 370) were short-lived
