Brain research is making it more and more evident that, while our environment and nurturing can make a crucial difference in what kinds of adults we mature into, nature deals us each a very definitive hand, and much of it is in the form of chemicals that our brains produce. If we don’t have enough seratonin, we feel depressed. If we are females and our estrogen and progesterone are out of whack, we get major PMS. (These are just two of hundreds of examples.)
Many of us women have come to recognize that we can control PMS – with everything from herbal supplements to wild yam cream, from progesterone suppositories to Prozac capsules. Because humans have evolved the way we have, it might be “natural” to be at the mercy of our erratic human brain and glandular chemistries, but that doesn’t mean we can’t take our fate into our own hands and alter those defective ebbs and flows. Doing so doesn’t make us less ourselves; indeed, it often frees us from the tyranny of our chemistries and allows us to be so much more our loving, caring, creative, and nurturing selves – in other words, better human beings.
Research has also made the connection between high levels of testosterone and violence/aggression/competitiveness. It has also made the connection between high levels of testosterone and sex drive.
