Abstract
A European survey was carried out in order to evaluate the incidence of chromosome anomalies in spontaneous abortions after IVF. Of the 34 abortuses analysed, 21 had a chromosome anomaly (62%), namely three with monosomy X,14 autosomal trisomies, one double trisomy, one triploidy, one tetraploidy and one translocation. These data show that IVF does not increase the incidence of chromosomal abortuses when compared with natural conceptions (60%).
摘要
为了评估体外受精（IVF）后自然流产中染色体异常的发生率，开展了一项欧洲调查。在分析的34例流产病例中，21例存在染色体异常（62%），即3例X单体型、14例常染色体三体、1例双三体、1例三倍体、1例四倍体和1例易位。这些数据表明，与自然受孕（60%）相比，IVF不会增加染色体异常流产的发生率。
