Monosomy X: a chromosomal anomaly associated with young maternal age.
In spontaneous abortions, monosomy X is associated with young maternal age. The finding is not explained by low paternal age or by gravidity. The association may be intrinsic to pregnancies of young women or it may be due to experiences which are commoner in young women.
