Premature Ejaculation

There you go guys. You no longer have to blame a lack of self-control. It seems as though scientists may have linked premature ejaculation to a gene. The only problem is that I am starting to get slightly cynical about the mountain of articles like this one that have come out over the last few years. What purpose does it serve to "know" the gene? Besides, we don't even know how genes are turned off and on.
