"The scientists, at the Hebrew University of Jerusalem, examined the DNA of 148 healthy male and female university students and compared the results with questionnaires asking for the students' self-descriptions of their sexual desire, arousal and sexual function. They found a correlation between variants in a gene called the D4 receptor and the students' self-reports on sexuality.
The results suggest that low sexual desire might be a normal biological condition rather than a psychological problem, the researchers say. Further, it might be possible to develop drugs to alter sexual desire based on the new findings."
