Have you heard the expression "love is chemistry?" It did not appear in vain: of course, one cannot reduce a complex and multifaceted feeling solely to chemical processes, but when we fall in love, our body begins to change. This applies not only to women who are considered to be sensitive individuals. It is known that the hormonal background of men also becomes completely different because of love. Moreover, depending on the stage of the relationship, the ratio of hormones in the male body also changes.
According to the theory of Helen Fisher, a researcher at Rutgers University, there are three main stages for each couple: attraction, attraction and attachment. The attraction stage usually lasts several months. At this stage, testosterone levels rise sharply in men. This is an absolutely natural process: it is the main male sex hormone, which is responsible, in particular, for the reproduction of sperm. According to the medical portal Healthline, testosterone levels directly affect a man's mood. For example, the production of an increased amount of testosterone during falling in love leads to an increase in sex drive, energy, and a feeling of elation.
What then happens in the second phase of a romantic relationship? The couple enters a phase of passionate love that lasts for several years. At this stage, the man's body begins to actively produce two main hormones: serotonin and dopamine, hormones of joy and pleasure. This is described in detail in the study "Depicting the Passionate Stage of Romantic Love with the Use of Domofina Dynamics" by Japanese researchers Kayo Takashi, Kei Mizuno, Akiro Sazaki and Masaki Tanaka. For a long time, they observed 13 volunteers at different stages of romantic relationships, and recorded changes in their hormonal levels.
Finally, in the last stage of romantic love, a strong attachment and a kind of friendship-love develops in a couple. The number of sexual contacts decreases, common interests and interesting pastime come to the fore. At this stage, the partners produce the hormones oxytocin and vasopressin. Interestingly, these hormones affect the male and female body differently. In 2004, in the United States, researchers Lim and Young conducted a famous experiment on meadow voles: they injected males and females with different amounts of oxytocin and vasopressin. As a result, it turned out that females felt strong attachment to partners with an increased level of oxytocin. On the other hand, males fell deeply in love when their vasopressin levels were high.
Of course, the question of the "science of love" has not been fully studied. In addition, love is such a complex and mysterious feeling that you shouldn't blame everything solely on hormones. But the connection of hormones with the degree of attachment of a man and a woman to each other and even with the ability to love is obvious.
