The Dabbs couple explore the profound and vast effects of testosterone on men and women from the youngest of ages (in utero) through mid-life. After childhood, they explore the three basic effects that are outlined in the title: creating heroes, rebel rousing and making lovers. While the presented research focuses on men, the Dabbs are frequently cite studies of women to establish a baseline of the norm before showing how testosterone changed the default behavior. This book has greatly expanded my understanding of, and provided fascinating insight to, why both men and women behave the way they do.
Interesting tidbit: Alfalfa and clover are estrogen rich and thus birth controlling plants. It is thought that the plants maintained this chemical feature to limit offspring of hungry animals and thus prevent overgrazing. Today, some million sheep go sterile each year in Australia alone from eating too much wild clover and alfalfa.
