Twelve XXY boys identified at birth in a population screening study were followed up at a mean age of 16.7 yr and compared with a control group of chromosomally normal boys matched for age and social class. Assessment of personality and psycho-sexual development showed the XXY boys to be more timid and less self-confident and to have problems in relating to their peer group than the controls. They also showed some evidence of delayed or impaired development of sexual interest. In general, the differences were not marked. Possible causes for these differences and potential methods of preventing them are discussed.
在一项群体筛查研究中出生时被鉴定为XXY的12名男孩，在平均年龄16.7岁时接受了随访，并与一组年龄和社会阶层相匹配的染色体正常男孩组成的对照组进行了比较。对个性和心理性发育的评估显示，与对照组相比，XXY男孩更胆小、自信心更弱，在与同龄群体交往方面存在问题。他们还表现出一些性兴趣发育延迟或受损的迹象。总体而言，差异并不显著。讨论了这些差异的可能原因以及预防这些差异的潜在方法。
