Instead of fueling aggression, it promotes attachment, reduces fear, and leads to feelings of pleasure and well-being. Testosterone appears in males at far higher levels than in females; oxytocin, on the other hand, is more prevalent in females. Women have many more oxytocin receptors in their brains than men do, and those receptors rev up during orgasm, childbirth, and breast-feeding …
