By understanding how that happens, scientists should in principle be able to help people like Washington for whom sex just isn't working. And indeed, over the past decade or two, scientists have identified many of the pieces of this complex puzzle. It clearly involves testosterone, along with other hormones, including estrogen and oxytocin, and brain chemicals such as dopamine, serotonin and norepinephrine. And there...
