Hormones of Love


Introduction

           Whenever someone makes a girlfriend or a boyfriend, it makes you wonder. Is it possible to fall in love with just one glance? What circumstances make a highly emotional feeling called “love”? Isn’t emotion also occupied by hormones made in body? Can it be pheromone that makes people to fall in love? Which chemicals work in process of love?


           With many questions bear in mind, love indeed is something that seems mysterious. Love is one of the most important emotions for a human to have. And love is also one of the most enjoyed emotions of a human. Love is something so complicated. At the same time, love is something so natural to take place in one’s daily life. I came up with scientific knowledges to know better about love and its process.



Definition

           To start with, it is necessary to define the word “love”. The word “love” has several meanings. However, the word “love” we are going to talk about is interpersonal love between a male and a female. The word “love” we’ll be dealing with is defined as “a very strong feeling of affection towards someone who you are romantically or sexually attracted to”.


Furthermore, I’ll define the word “hormone” since hormone is the main concept to explain the process of love. A hormone is a chemical, usually occurring naturally in your body, that makes an organ of your body do something. And indeed, hormone is capable of creating emotions we feel.

Stages of Love


           Helen Fisher, a leading expert in the topic of love, divides the experience of love into three partly overlapping stages: lust, attraction, and attachment. Lust is the feeling of sexual desire. Attraction determines which partner to find attractive and pursue. And attachment involves sharing home, parental duties, and mutual defense. Three distinct hormones, and also three behavioral patterns, are associated with these three romantic styles.


ⅰ. Lust

           At the first stage of love, hormones called testosterone and estrogen participate. Those two hormones are the most influential after all. Testosterone and estrogen make us to have good feeling toward the other sex. Testosterone makes a man manly, and estrogen enables a woman to have beautiful body. Also testosterone takes part in concentration, memorization, and space perception. Estrogen takes part in numerous physiological functions such as boosting metabolism, decreasing muscle tissues, adjusting menstruation rhythm. Moreover it is quite surprising how similar testosterone and estrogen looks.


ⅱ. Attraction

           The second stage of love is when you become attracted to the partner. At this stage, we often say “You are fallen love.” You become impossible to concentrate on other things beside your mate. Moreover, you may suffer insomnia. In worst case, you may even lose your appetite. At this stage, you start to stutter and your heart starts beating faster in front of your lover.


These symptoms are caused since several chemical compounds are actively made. Those chemical compounds made are called monoamine. Norepinephrine, serotonin, dopamine belongs to category of monoamine. Norepinephrine and serotonin make you excited. And dopamine makes you feel happiness. Thus norepinephrine, serotonin, dopamine are called compounds of love.


           An anthropologist from Rutgers University, Helen Fisher warns that there are some antidepressant drugs that facilitate production of serotonin too much, patients can rather find trouble having a romantic love. Helen Fisher says you are able to fall in love when amount of serotonin in your body is relatively low.


ⅲ. Attachment

The third stage of love is the stage of attachment. In this stage, beyond feeling the attraction, you feel satisfaction of being together with your mate. In this stage of love two hormones take an important role. Oxytocin and vasopressin are those two hormones. Oxytocin and vasopressin are nanopeptide. Nanopeptide is a compound of nine amino acids connected to each other.


Oxytocin increases attachment between lovers. Because of its ability, oxytocin has nickname called “compound of hug”. Also for female, oxytocin helps uterus shrinks while delivery, and ables breast feeding. Moreover oxytocin manifestoes maternal affection. Oxytocin in the blood increases regardless of sex, when they feel orgasm. Oxytocin is made in neurons of hypothalamus then moves to axon of pituitary gland and finally released to blood.


           Another attachment inducing hormone is vasopressin. Vasopressin also has a nickname called “compound of monogamy”. Only three percent of mammals are capable of instinct monogamy. Unfortunately human aren’t included in three percent, sometimes making marriage complicated. Rats are kind of animal that keeps monogamy, most of the results of the research on vasopressin are based on experiments on rats. After a male rat has copulation, in order to protect its mate, the male rat becomes really aggressive and they keep their attachment toward its mate. Since amount of vasopressin in their brains are relatively high while those actions of male are taken place, vasopressin is believed to take a vital role in maintaining the attachment of a mate.


           Since vasopressin is made in the same place as oxytocin is made, two hormones must be closely related. Even if we look at its chemical structure, only two of nine amino acids differs each other. Furthermore endorphin (an anodyne that our body makes) also is believed to be related in keeping the attachment. 




ⅳ. Conclusion

           It’s really impressive that totally different hormones work in the three stages of love. This means that our mental state can be read by compounds of chemical made in our body. Although, current technologies are still far away from reading our mental state accurately with compounds of chemical, there are numerous possibilities of improvements.


           By understanding which compounds of chemical have effects on our emotions, we can cure lots of mental diseases. Status quo, mental diseases aren’t easy ones to deal with. Surgery is too dangerous, and drugs have many side effects. Not only that, by understanding hormones we may be able to understand more about each other. We can know how they feel, how they think, and about their ideas. By stepping into one’s shoes (understanding each other) is the way that we can truly solve problems. We can truly change the world.
