The biological basis of the moon and the water

Scientific studies of sexual desire and neurological chemicals associated with this state have shown that the motivation for people to go to sexual activity is mainly due to the chemical reactions taking place in the set. Brain.

Real life also proves that sexual acts sometimes do not come from love or desire to establish a long-term relationship, but merely because of the need for complete physical.

The biological origin of sexual behavior

The biological origin of sexual behavior is the hypothalamus - an area of ​​only a few centimeters in the brain but plays a very important and complex role in regulating and controlling instinctive behaviors such as eating. drink or sex.The hypothalamus is already present in many low-level organisms and develops earlier than many other brain structures that control complex human thinking processes such as memory and language.The hypothalamus, along with other organs, regulates testosterone levels - hormones that produce stimulation and sexual activity.Sexual behavior of many animals and of all humans is related to the concentration of testosterone.For both men and women, testosterone levels affect sexual desire and action.However, unlike animals, there is no absolute correlation between hormone levels and sexual behavior, and there is also an intervention role of consciousness.
Another chemical that has also been discovered is related to sexual behavior, which are neurotransmitters that ensure communication between brain cells.Psychiatrist Michael Liebowitz is one of the first people to study neurophysiology in love and sex.He found that there were people who were easy to get into love affairs even though they were not suitable, but they were easy to get bored, rather than their partners like changing clothes.He thinks these people may be deficient in phenylethylamine (PEA) - a chemical of the brain that has an amphetamine-like structure that governs feelings of pleasure and excitement.Because of the prolonged shortage of this chemical, the litigants went to seek "fun" in romantic or sexual encounters.Michael Liebowitz gave these people a monoamine oxidase inhibitor (IMAO) - an antidepressant that affects phenylethylamine levels as well as other levels of neurotransmitters such as dopamine, serotonin and norepinephrine.After being treated, many patients have gone out of their "moonlight" routine, looking for "love at all costs", maybe because they do not feel lonely is heavy or have become confident, more cautious in choosing a partner.They do not need the same excitement as when it comes to love affairs - a state like the use of amphetamine.

In addition to phenylethylamin, new discoveries also found two other hormones, ocytocine and vasopressine, that also play an important role in sex and love.The concentration of these two hormones in the blood increases in both men and women when they are sexually excited and when ejaculating.Excretion of ocytocine also seems to play an important role in the development of emotional relationships, encouraging the pairing of partners.Larry Young and his colleagues in the Department of Behavioral and Psychiatry Sciences, Emory University discovered that ocytocine is one of many other neurological chemicals that regulate many social behaviors The calculation of the monogamy regime, in which male and female couples are paired up and the father teaches the children.

Helen Fischer, a female researcher and collaborator of Rutgers University anthropology, affirmed that the system of neurological chemicals in the human brain has evolved towards encouraging male and female attractiveness and delivery. coordinated, to make the partner couple maintain the time needed to breed and raise children.

Differences in human sexual behavior compared with animals

As mentioned, there is no absolute correlation between hormone levels and sexual behavior in humans because there is also an intervention role of consciousness.The development of consciousness (the biological basis is the cortex) has made human sexual behavior develop in three positive directions, different from the animal world:

Knowing the exclusion and critique : Limiting the metaphysical inferiority complex, criticizing the denial of the role of women in sex life, knowing their partners according to good standards (In addition to appearance also to consider intellectual capacity, moral qualities, souls), not seeking sexual satisfaction at all costs.This feature is the basis for the faithful relationship between husband and wife as well as the avoidance of AIDS and many other depraved traps.

Know how to develop and nurture sexual function : Enrich your imagination with cultural products, create conditions for sexual reactions, make sex escape the influence of consciousness (no birth activity Which is more sensitive to cortical activity like sexual physiology .).

Refining and improving : Considering inferior sexual behaviors, promoting the sex life of each individual (making sexual activities more meaningful and reassuring by inventing the methods Contraceptives, help people master the harsh physiological laws of reproduction), pay attention to enrichment factors, add more life .
