The Science of Orgasm: Body & Brain in Action
How men and women experience climax — a visual summary of the body, brain, hormones, and key differences.
What Happens in the Body
Blood flow, muscle contractions, and physiological arousal.
The Brain During Orgasm
Key regions that light up during climax.
Hypothalamus — hormone release
Amygdala — emotional intensity
Nucleus accumbens — reward center
Prefrontal cortex — quiets down (less self-conscious thought)
Functional imaging shows reward, motor, and emotional areas activate during climax.
The Chemistry of Pleasure
Hormones released around orgasm and their common effects.
Oxytocin
Supports bonding and feelings of closeness after orgasm.
Prolactin
Increases after climax; tied to sexual satisfaction and refractory period.
Endorphins
Natural painkillers that boost mood and relaxation.
Questions Science Is Still Exploring
Areas under active research.
- Why some men and women struggle to reach orgasm while others do not.
- The roles of genetics, anatomy, and mental state.
- Potential long-term health or evolutionary benefits.
