High levels of testosterone may suppress oxytocin and vasopressin (chemicals associated with attachment love), which may explain why men with higher testosterone levels tend to marry less often, be more abusive in their marriage, and divorce more. When a man holds a baby, his testosterone goes down, perhaps as a result of increased oxytocin and vasopressin.
Love and Lust in Brain
Brains in love and brains in lust are not identical. Erotic photos activate the hypothalamus (which controls hunger and thirst) and the amygada (arousal) areas of the brain. Love activates areas of the brain with a high concentration of receptors for dopamine (associated with euphoria, craving, and addiction) and its relative, norepinephrine.
