The Science Behind Attraction, Desire, and Oxytocin
By Dr. Debra Durst, MD – Founder, RevitalyzeMD
TL;DR
Attraction isn’t just emotional—it’s chemical. The science behind attraction, desire, and oxytocin reveals how brain chemistry and hormones like dopamine, testosterone, and oxytocin fuel connection, pleasure, and long-term bonding. From pheromones that spark initial interest to oxytocin that deepens love and trust, it’s proof that passion truly begins in the brain—not the heart.
Attraction Starts in the Brain, Not the Heart
When you feel that spark, it’s not your heart—it’s your brain. Attraction activates the brain’s reward system, releasing dopamine, the neurotransmitter behind excitement, motivation, and euphoria.
Dopamine explains why infatuation feels addictive—it’s your brain craving another “hit” of pleasure. For women especially, attraction and desire are largely mental, reinforcing the saying that 99% of sex happens in the brain.
Pheromones: The Invisible Signals of Attraction
The hormones testosterone and estrogen drive desire in both men and women. The brain’s hypothalamus acts as command central, triggering sexual motivation and response. When these hormones are balanced, they heighten arousal, confidence, and sensitivity—key ingredients for a thriving intimate connection.
Hormones like testosterone and estrogen don’t just affect libido—they influence mood, confidence, and overall vitality. At RevitalyzeMD, we specialize in personalized Hormone Optimization and TRT (Testosterone Replacement Therapy) to help men and women rebalance their hormones, restore energy, and reignite desire.

Evolutionary Roots of Attraction
Our biological wiring hasn’t changed much since early humans. Traits like clear skin, confidence, and symmetry are evolutionary markers of vitality and fertility. These ancient cues still influence modern attraction, shaping who we’re drawn to and why certain qualities feel irresistible.
Oxytocin: The Love & Bonding Hormone
Known as the “cuddle chemical” or “love hormone,” oxytocin is released during closeness, touch, and orgasm—strengthening trust, empathy, and connection. Levels of oxytocin can spike up to five times higher during orgasm, helping to “lock in” intimacy and emotional attachment.
Today, oxytocin is available in dissolvable tablets or nasal sprays, designed to mimic the body’s natural release and enhance connection. While it’s not a magic love potion, it does help the brain associate intimacy with safety, calm, and pleasure—deepening emotional bonds. Learn more about our Sexual Wellness treatments.
