Stages of love/Neurochemistry of Love

  1. 1. Neurochemistry of Love “The stages of love”
  2. 2. Stage 1:Lust/Romantic Feelings Lust is driven by SEX hormones; Testosterone and Estrogen. During this stage of love, your partner seems “perfect” or ideal for you, because of endorphins soak your brain.
  3. 3. Testosterone: Testosterone is a steroid hormone that starts the development of male and some female sexual characteristics/drive. Testosterone is produced in the testes, ovaries, and adrenal cortex.
  4. 4. Estrogen: Estrogen is a steroid hormone that promotes the development and maintenance of female physical and sexual characteristics. Estrogen is an important factor for menstrual and estrous reproductive cycles. Estrogen is produced in the ovaries, adrenal cortex, placenta, and testes.
  5. 5. Stage 2: Physical Attraction: Physical attraction is also known as the “love-sick” phase, and is controlled by three neurotransmitters; adrenaline, dopamine, and serotonin. During this stage you daydream about your partner all day, and they are the center of your attention, causing you to lose appetite, and need less sleep.
  6. 6. Adrenaline/Epinephrine: Adrenaline activates stress responses, also increases blood and cortisol levels. Adrenaline creates a charming effect when you meet your partner, you start to sweat, your heart races, and your mouth goes dry. Once adrenaline is secreted by adrenal glands it prepares muscles for exertion, and your blood pressure sky rockets; creating a strong physical attraction to one another.
  7. 7. Dopamine: Dopamine stimulates “desire and reward” by triggering intense rushes of pleasure; the same effect as snorting cocaine. Dopamine plays a huge role in cognition, mood, sleep and attention. Dopamine or the pleasure chemical is why you think about your partner all day, and lose sleep. Studies show that dopamine is a main cause of schizophrenia and Parkinson’s disease.
  8. 8. Serotonin: Serotonin’s effects of being infatuated with your partner have a similar chemical appearance to OCD, which explains people experiencing infatuation cannot think of anyone else. Serotonin also regulates appetite, sleep, memory, and mood/behavior; and is a vital role in physical attraction.
  9. 9. Stage 3: Emotional Attachment/ Unconditional Acceptance: Emotional attachment includes commitment, partnership, children, and can recognize both positive and negative traits towards their partner. In this stage is when you and your partner will either work towards a healthy/loving relationship or decide to quit all together.
  10. 10. Oxytocin: Oxytocin, also known as the cuddle hormone is a powerful hormone released by men and women during orgasm. Although both genders produce oxytocin during sex it is enhanced by estrogen. Oxytocin strengthens the bond between partners. The theory is the more sex and hugs a couple has, the stronger and deeper the connection between them becomes.
  11. 11. Vasopressin: Vasopressin is an important chemical that is released after sex. Testosterone enhances the effects of the vasopressin and heightens a man’s responsibility, monogamy, also giving them protective, jealous, and loyal feelings towards their partner.
