“Dr. Helen Fisher divides love into three categories that correspond to different hormones and brain systems. Her analysis of the data suggests that high androgen and estrogen levels generate lust, romantic love correlates with high dopamine and norepinephrine and low serotonin, and attachment is driven by oxytocin and vasopressin. To make matters more complicated, these three systems interact. For example, testosterone can “kickstart the two love neurotransmitters while an orgasm can elevate the attachment hormone,” according to Fisher. “Don’t copulate with people you don’t want to fall in love with,” she warns.4”
