以色列科学家发现,人体内的多巴胺第四型受体(DRD4)基因表现会影响大脑对化学物质多巴鞍的反应。这种化学物质可以影响性欲。以色列耶路撒冷大学的Richard Ebstein与其同事对148位男女学生的DNA进行了检测,研究DRD4基因在不同人身上的变化。同时学生们还要完成一份性欲评估的问卷调查。研究发现,大约30％的人身上存在一种DRD4基因的变量,有这种基因的人性欲要比别人强。因此,性欲的差别与基因有很大关系。不过也有专家认为,这个结论应该以更大的受试者来做研究才可以确定DRD4基因的影响力,或许其它一些基因和社会因素也会影响人的性欲。
Israeli scientists have discovered that the expression of the dopamine type 4 receptor (DRD4) gene in the human body affects the brain’s response to chemical substance dopa saddles. This chemical can affect sexual desire. Richard Ebstein of the University of Jerusalem, Israel, and colleagues tested the DNA of 148 male and female students and studied changes in the DRD4 gene in different individuals. At the same time, the students also completed a questionnaire on sexual desire assessment. The study found that about 30% of people have a variant of the DRD4 gene, which has a stronger human sexual desire than others. Therefore, the difference in sexual desire has a lot to do with genes. However, some experts believe that this conclusion should be studied with larger subjects to determine the influence of the DRD4 gene. Perhaps other genetic and social factors also affect people’s sexual desire.
