The Chemistry of Love

Literature often describes love as an uplifting feeling. Numerous people, from poets to artists, from writers to philosophers, have been attempting to discover the causes and origins of this feeling. Today, in the 21st century, people have become more pragmatic. They are seeking for biological origins of love to explain it. Many scientists explore the evidence of the chemical foundation of love using technological achievements.

Dr. Fisher, an anthropologist at Rutgers University, says that love is a holistic system that may be subdivided into three subsystems that include sex drive, romantic love, and attachment. They all differ in their nature. Sex drive makes a person search for a partner. Romantic love makes an individual concentrate on a single partner. Attachment makes one want a long-term relationship with the chosen partner.

Nevertheless, neither of these subsystems of love could take place without a driving force that influences the behavior of a human. Even though love is traditionally referred to in psychological terms, it also entails the influx of certain hormones. The involvement of hormones is what substantiates the term “chemistry of love.” For instance:

  • Estrogen and testosterone invoke sex drive.
  • Serotonin and dopamine cause romantic love, inducing the stage of attraction.
  • Vasopressin and Oxytocin evoke attachment.

The production of estrogen (female hormone) and testosterone (male hormone) cause the desire of looking for a partner in individuals, being responsible for lust and sex drive. In the case of an influx of serotonin and dopamine into the brain, romantic feelings are induced. These hormones are also responsible for the improvement of one’s mood and the emergence of romantic feelings. Interestingly, the same hormones that cause sex drive and romantic love are produced after taking drugs. Under the effect of these hormones, an individual may act impulsively. Oxytocin, in its turn, is the hormone that is responsible for the most lasting stage of love, such as the love of a mother and a child. It is produced when two partners get intimate. This is the exact reason why the lasting relationships are characterized by tenderness, not with turbulent feelings.

Today, love has acquired not only psychological but also physiological explanation. Namely, being a psychological process, it is also deeply connected with the secretion of hormones in different stages of relationships. Each of the three stages is characterized by the influx of a certain hormone into the brain. This is the way the term “chemistry of love” can be explained from the scientific point of view.
