A meta-analysis of sexual-arousal research found that physiological genital arousal and self-reported subjective arousal are not always closely matched, and the degree of concordance differs between individuals and groups.
In a controlled human experiment involving 22 women, researchers measured oxytocin before and after two kinds of social conversation. Oxytocin increased significantly after the women engaged in gossip—a socially bonding form of conversation
Female genital arousal involves parasympathetic nervous-system activity, smooth-muscle relaxation, nitric-oxide signaling, and increased blood flow to pelvic tissues. Stress-related sympathetic activation can interfere with those vascular p
Perimenopause is not only a reproductive transition. Neuroendocrine research describes it as a neurological transition. Symptoms that can accompany changing estrogen signaling include disturbed sleep, changes in circadian regulation, sensor
Human hairy skin contains specialized low-threshold C-tactile nerve fibers that respond strongly to slow, gentle, skin-temperature touch. These pathways are associated with affective, socially meaningful touch rather than precise location s
1. Your body has its own cannabinoid system. It’s called the endocannabinoid system (ECS): a signaling network that runs through the whole body. The two main receptors are CB1, found mostly in the brain and nerves, and CB2, found mostly in
Research involving women with complete spinal-cord injury has demonstrated brain activation during vaginal or cervical stimulation and orgasm, supporting the existence of sensory signaling through the vagus nerve that can bypass the spinal
